Product scope

Custom Fastener Categories

Classify the requirement before discussing process or price. A bill of materials containing several families can stay within one coordinated RFQ, but each part should retain its own drawing, revision and acceptance criteria.

Custom Bolts Made to Drawing

Choose the custom bolt category when the part is externally threaded and the head, shank, shoulder, grip length, thread runout, bearing face or load path drives the design. The drawing should identify critical diameters, under-head length, thread system and class, material and mechanical requirements, heat treatment, finish and any safety-critical function. Order-specific review confirms whether a modified standard blank, forming, forging, machining or a combined process is feasible.

Custom Screws Made to Drawing

Choose the custom screw route when head profile, drive or recess, point, thread-forming behavior, shoulder, captive feature or substrate interaction controls the assembly. Custom screw manufacturers need the mating component, installation method and functional acceptance criteria as well as the nominal dimensions. Standard self-tapping and self-drilling applications should remain in their dedicated product families rather than being treated as made-to-print work automatically.

Custom nuts made to drawing for industrial RFQ review through verified Turkish manufacturers

Custom Nuts and Internally Threaded Parts

Choose the custom nut route when the internal thread, body geometry, prevailing-torque feature, bearing face, proof requirement, mating part or press-fit relationship controls the program. Include the mating bolt or stud designation, engagement, coating allowance and thread-gauge requirement. Nut class or grade must be compatible with the joint specification; it should never be inferred from a drawing title alone.

How to specify

Review the custom fastener requirement by input area

Classify the requirement, then confirm the workflow, the quotable specification fields and the evidence and export package that let the RFQ be quoted on one basis.

Custom bolt, screw and nut categories

Classify the requirement before discussing process or price. A custom bolt is governed by external-thread geometry and load transfer; a custom screw adds drive, point and assembly details; a custom nut is controlled by its internal thread, mating fastener and proof or functional requirement.

Custom fastener workflow from drawing and process review through tooling, sample approval and serial packing

From drawing review to serial production

Made-to-print custom fasteners move through a controlled sequence: drawing intake, blocking-question review, order-specific process feasibility and tooling review, quotation, sample or first-article approval when required, and serial-order release.

Review the drawing-to-production sequence

Inspection, documentation and traceability

Replace generic quality claims with an order-specific evidence plan. The RFQ should name the required document, issuer, scope, language and submission stage so material, dimensional, coating and approval records are quoted as defined deliverables.

Define the inspection and document package

Custom fastener export flow from protective packaging to pallet, container and destination-port review

MOQ, tooling, lead time and export terms

Custom-fastener quotations are project-specific. First-order quantity and annual volume influence whether dedicated tooling, a modified standard part, machining or another route is economical, and packaging, destination and Incoterm affect both price and schedule.

How we work

How We Supply Custom Fasteners from Turkey

FastenersFromTurkey receives the RFQ and checks whether the information is sufficient for an order-specific feasibility and supply-scope review. Product family, geometry, material, production process, tooling, annual volume, quality plan, required documents, packaging and destination are assessed before a quotation is issued. Actual manufacturing capability is confirmed for the controlled requirement.

One accountable commercial relationship

FastenersFromTurkey coordinates the technical question list, quotation, approval sequence, documentation scope and export communication. The commercial relationship remains direct and accountable while production responsibility stays with the manufacturer selected for that RFQ.

How we review a custom fastener RFQ

Each RFQ is reviewed against evidence rather than a generic catalogue match. A cold-heading program, a machined prototype, a forged safety-critical part and an internally threaded special component require different process, tooling and inspection profiles. Material formability, deformation limits, secondary operations, local tolerances, heat treatment, coating, tests and forecast volume are assessed together. Open items are returned as blocking questions instead of being converted into silent assumptions.

Manufacturer evidence and commercial confidentiality

Manufacturer identity, machine lists, customer drawings, quotations and non-public certificates remain confidential. Capability or approval claims are published only when their holder, scope and validity are verified and disclosure is approved. Buyer files should carry the correct drawing number, revision and distribution restriction so feasibility, samples, inspection records and serial orders all refer to the same controlled requirement.

Workflow

From Drawing Review to Serial Production

Made-to-print custom fasteners move through a controlled sequence: drawing intake, blocking-question review, order-specific process feasibility and tooling review, quotation, sample or first-article approval when required, and serial-order release. Every stage should preserve revision control and clearly identify any approved deviation.

Drawing, revision and critical-characteristic review

Submit the drawing number, revision, units, datums, critical dimensions, tolerances, thread designation, material, mechanical requirements, finish and referenced specifications. Identify features that affect fit, clamp load, sealing, locking, rotation, electrical contact or another function. If the part mates with another component, include the interface, installation method and acceptance criteria. The approved drawing and purchase specification govern custom geometry; a convenient catalogue standard must not be substituted without approval.

Manufacturing route and feasibility review

The route may involve modifying a standard part, cold heading or forging, hot forging, machining, thread rolling, heat treatment, coating or a combination of operations. Geometry, material flow, local tolerances, surface requirements, volume and tooling economics determine the practical route. Process names on a website do not establish feasibility for a specific drawing; confirmation belongs in the manufacturer's documented review and quotation.

Tooling, prototype, first article and PPAP

Dedicated forming, trimming, rolling or checking tools may be required. Tooling ownership, maintenance, life, change control and non-recurring engineering should be separated from unit pricing. Prototype or machined samples can support early geometry and fit checks, while first-article or PPAP submissions may be required for customer approval. State the sample quantity, PPAP level, inspection records and approval sequence in the RFQ so they can be quoted as defined deliverables.

Specification matrix

Specification Matrix for a Quotable Custom Fastener

The matrix below closes the fields most likely to delay feasibility or pricing. Use an exact designation where the drawing already controls the requirement; otherwise identify the field as open for customer engineering review.

RFQ field	Required input
Product family	Bolt, screw, nut, internally threaded part or other drawing-led fastener
Drawing control	Drawing number, revision, units, datums and governing purchase specification
Geometry	Critical dimensions, tolerances, surface finish and functional characteristics
Thread	Metric, UNC or UNF; nominal size; pitch or TPI; class; length; handedness and runout
Material	Exact material designation and any approved alternative route
Mechanical requirement	Property class or grade, hardness, heat treatment and required test method
Finish	Coating or finish, thickness limits, friction needs, color and corrosion endpoint
Functional feature	Locking, sealing, prevailing torque, captive component or bearing interface
Risk	Safety-critical status, fatigue duty, service environment and substitution approval
Quality evidence	Inspection plan, material records, dimensional/thread results and applicable tests
Approval	Prototype, first article, PPAP level, samples and approval sequence
Commercial	First-order quantity, annual volume, tooling status and target date
Export	Packaging, labels, destination, preferred Incoterm and named place or port

Dimensions and threads

Dimensions, Thread Systems and Tolerances

Define the thread system, not only the nominal size

Nominal size is only one input. Define external or internal thread, metric or Unified inch system, coarse or fine pitch, fit class, thread length, start, runout and coating allowance. Metric and UNC/UNF threads are separate systems and are not interchangeable. Control critical head, shank, shoulder, body, bearing, concentricity or press-fit dimensions individually rather than relying on a broad title-block tolerance for every function.

Material and mechanical

Materials, Mechanical Requirements and Heat Treatment

Specify material, class and heat-treatment condition separately

Material identity, property class or grade and heat-treatment condition are separate requirements. Specify each one when applicable and identify the governing test or customer specification. Carbon, alloy, stainless or non-ferrous options can be assessed only against a defined part and order-specific production capability. Requests for custom titanium fasteners require the exact alloy, geometry, process, mechanical properties, tests, quantity and documents before availability or feasibility can be confirmed.

Coating and corrosion

Coatings, Corrosion Targets and Locking Features

State the finish, corrosion endpoint and locking requirement

State the coating or finish, local thickness limits, corrosion-test method and endpoint, friction or lubricant requirement, and any locking or sealing feature. White- and red-corrosion criteria are different; test exposure is not a field-service-life guarantee. High-hardness or safety-critical parts require a process-specific hydrogen-embrittlement review where cleaning and coating routes create exposure. Any material, class, coating or locking substitution requires customer engineering approval when function or safety can change.

Evidence plan

Inspection, Documentation and Traceability

Replace generic quality claims with an order-specific evidence plan. Depending on the drawing and purchase specification, the package may include material records, dimensional reports, thread-gauge results, mechanical test records, coating-thickness or corrosion-test evidence, first-article or PPAP documents, lot traceability and third-party inspection.

Name the document, issuer, scope, language and submission stage

The RFQ should name the required document, issuer, scope, language and submission stage. Evidence is checked against the applicable order and manufacturer; it is not represented as FastenersFromTurkey-owned certification.

Keep identity, lot and shipment records connected

Heat or material identity, manufacturing lot, inspection status, packing label and shipment documents should remain connected through the agreed traceability method.

Review fastener quality and documentation support

Commercial and export

MOQ, Tooling, Lead Time and Export Terms

Custom-fastener quotations are project-specific. First-order quantity and annual volume influence whether dedicated tooling, a modified standard part, machining or another route is economical. Material availability, heat treatment, coating, sample approval, tests, documents, packaging and destination also affect price and schedule. Provide these inputs together so tooling/NRE, samples and serial parts can be shown as separate commercial lines where appropriate.

What determines a project-specific quotation

MOQ and lead time are confirmed after order-specific review of geometry, process, tooling, material, finish, quantity and approval requirements. A prototype quantity may differ from the serial MOQ. Changes to the drawing, sample plan, PPAP scope or test plan can change both cost and timing, so the quotation should identify its revision basis, validity and open assumptions.

Packaging, destination and Incoterms

State pieces per pack, inner and outer protection, pallet constraints, corrosion protection, lot separation, barcode or label format and required shipping documents. Preferred terms may include EXW, FOB Turkish port (Istanbul, Izmir/Aliaga, Mersin, Gemlik, Iskenderun or Derince), CFR or CIF destination port. The final Incoterm, named place or port, freight responsibility, cost and delivery schedule are confirmed in the quotation.

RFQ FAQ

Frequently Asked Questions

What information is required for a custom fastener quotation?

Send the drawing and revision, product family, dimensions, thread, tolerances, material, mechanical requirements, coating, corrosion or locking requirements, inspection documents, prototype or PPAP needs, order quantity, annual volume, packaging, destination and preferred Incoterm.

Can custom fasteners be produced from a drawing?

Yes, drawing-led requirements can be reviewed for quotation. The approved drawing and purchase specification govern the part. Geometry, tolerance, material, process, tooling, validation and commercial feasibility must be confirmed by the selected Turkish manufacturer before an offer is issued.

How is a custom fastener RFQ reviewed?

FastenersFromTurkey reviews the product family, geometry, material, production process, tooling, annual volume, quality plan, documentation and destination. Order-specific manufacturing capability and supply scope are then confirmed before quotation.

Which production method is suitable for a custom fastener?

The suitable route may be modification of a standard part, cold heading or forging, hot forging, machining, or a combined route. The decision depends on geometry, tolerance, material, mechanical requirements, quantity, annual volume and tooling economics, so it is confirmed during feasibility review.

Are tooling, prototypes or PPAP required?

Tooling, prototype, first-article and PPAP requirements depend on the selected process, drawing, customer approval plan and annual volume. State the required sample quantity, PPAP level, inspection records and approval sequence in the RFQ so these items can be quoted separately.

Can titanium custom fasteners be supplied?

Titanium requirements can be assessed only after the exact alloy, geometry, process, mechanical properties, testing, quantity and documentation are known. Availability and feasibility must be verified with a suitable Turkish manufacturer; titanium is not assumed as a standard capability.

Which export terms should be included in the RFQ?

State the delivery destination, packaging and labelling requirements, preferred Incoterm and named place or port. Requests may specify options such as FOB Turkish port, CFR or CIF destination port, but the final term, costs and delivery schedule are confirmed in the quotation.

Thread designation alone does not define a functional custom fastener. The controlled requirement should also identify fit class, mating component, coating allowance, gauge or inspection method and the characteristic that performs the work. These inputs prevent a dimensionally plausible part from failing during assembly or service.
