Self-drilling metal screws are specified as a system. Point, thread, diameter, length, head, drive, washer, material and finish must work together in the intended joint. A familiar head shape does not establish drill capacity or mechanical performance.
The point number identifies a drill-point geometry, not a universal steel-thickness guarantee. Point length, flute length, diameter, steel grade, total stack-up and supplier test data determine whether the screw completes the hole before the threads engage.

Hex, pan, wafer and countersunk heads with bonded sealing washers are matched to tool engagement, bearing area, flush seating and weather sealing. Washer selection must reflect the panel surface, service temperature and exposure.
Request Quote
The correct point is selected from the joint, not the screw name. Start with steel grade and hardness, then calculate the complete thickness the drill point must cross. Point and flutes must clear this stack before full threads engage.

Specification review, dimensional inspection, material or mechanical records, coating-thickness or corrosion-test reports, lot traceability and agreed third-party inspection are established before quotation when they are part of the buyer requirement.
Request QuoteStandards can define dimensions, head style, thread form or mechanical and functional properties, but no single reference covers every self-drilling screw configuration. State the governing standard edition and exact product form, and provide the joint drawing rather than relying on a generic online chart.
| RFQ field | What to specify | Why it matters |
|---|---|---|
| Drill point and thread | Point type or required drilling capacity; thread designation | A TEK or drill-point number is not a universal performance rating |
| Size and length | Diameter, length and measurement basis | Sets flute clearance and engagement in the receiving layer |
| Head, drive and washer | Hex, pan, wafer or countersunk head; drive; bonded washer form | Aligns seating, tooling, bearing area and weather sealing |
| Substrate and stack-up | Steel grade, hardness and total joint thickness | Confirms the point clears the stack before full threads engage |
| Material and coating | Carbon or stainless; zinc, zinc-flake or corrosion-test target | Links coating thickness and hydrogen-embrittlement controls |
| Standard reference | ISO 15480/15481/15482/15483, ISO 10666 or SAE J78 | Confirm the exact head, recess and current reference before substitution |
| Documents and delivery | MTC type, inspection, quantity, packaging, destination and Incoterm | Sets the eligible route and commercial quotation basis |
As a Turkey-based fastener supplier and exporter, we review the joint, drilling requirement, screw configuration, documentation, quantity and destination before confirming a commercially workable option.
Steel grade, hardness, total stack-up, edge distance, installation speed and tool setting are reviewed before a drill-point configuration is proposed.
ISO 15480/15481/15482/15483, ISO 10666 and SAE J78 scope is checked against the exact head, recess and drawing; legacy DIN 7504 equivalence is verified before substitution.
Point type, dimensions, material, coating, head and washer, quantity, packaging, documentation, destination and Incoterm are consolidated into the RFQ.
Documentation scope is confirmed for the reviewed order specification and supply scope. These documents are not interchangeable and must be requested before quotation.
Type 3.1 or 3.2 material documentation can be reviewed when it applies to the chosen manufacturer, product and customer program. State the required type, witness point and report format in the RFQ.
Dimensional inspection, material or mechanical records, coating-thickness or corrosion-test reports, lot traceability and agreed third-party inspection can be coordinated as applicable.
Certificate of origin, packing list, commercial invoice and PPAP/APQP support can be reviewed when they apply to the manufacturer, product and customer program.
Self-drilling screws may be reviewed for metal studs, light-gauge framing, sheet-metal assembly, metal roofing and cladding, and wood-to-metal or other mixed-material joints.
Confirm the number of layers, receiving-member thickness, edge distance, access and installation method. A fastener that works in one thin sheet may not have enough flute clearance for a multi-layer joint.
Head bearing area, bonded washer geometry, panel coating, support thickness, weather exposure and installation compression influence sealing. Specify the washer material and corrosion or weathering target.
Provide the layer order and thicknesses, required pull-out resistance and head-seating condition so there is enough clearance through the upper material before the screw drills and taps the steel support.
Provide the standard or controlled drawing, drill-point type or drilling capacity, screw dimensions, substrate grade and total thickness, head, drive, washer, material, coating, quantity and destination.
We identify drilling-capacity, sealing, document, packaging or commercial points that need confirmation for the actual joint and approved product data.
Order-specific feasibility and the agreed inspection/document package are confirmed for the RFQ.
The quotation defines scope, packing, Incoterm and delivery assumptions for buyer review.
A correctly selected self-drilling screw is designed to create its own pilot hole and mating thread in one operation. Pre-drilling may still be required when the substrate, hardness, total thickness or application is outside the verified drilling capacity of the selected screw.
A self-drilling screw has a drill-point tip that creates the hole before the threads engage. A self-tapping screw creates or forms a thread in a prepared or suitable hole but does not necessarily include the drill-point geometry required to drill through the substrate.
The point number identifies a drill-point geometry used for a defined drilling-capacity range. The permitted steel thickness must be confirmed from the exact product and supplier test data rather than from a universal generic chart.
Yes, when the screw point, diameter, material and installation conditions are matched to the steel grade and total thickness. Send the substrate and stack-up details so the drilling capacity can be verified before quotation.
Provide the standard or drawing, diameter, length, thread, drill point or required drilling capacity, substrate and thickness, head, drive, washer, material, coating, quantity, documentation, packaging, destination and preferred Incoterm.
Share the governing standard or controlled drawing together with the drill-point type, joint stack-up, material, coating, quantity, documentation and destination. We will review open technical and commercial points before quotation.

A TEK or drill-point number is not a universal performance rating. Send the substrate grade, total thickness and stack-up so drilling and fastening capacity can be validated for the actual joint.

For a prepared or punched hole without an integrated drill point, send the material grade, thickness and pilot-hole condition for a self-tapping review.

Request QuoteDrill-point capacity depends on substrate grade and thickness, point geometry, installation speed and axial load. A TEK or drill-point number is not a universal performance rating; drilling and fastening capacity must be validated for the actual joint and approved product data.
