Gypsum TEK Self-Drilling Screws (Heavy Gypsum to Steel)
Gypsum TEK self-drilling screws as printed by the collected special-purpose table: No. 6 at .035"–.090" and No. 12 / No. 14 at .089" min to .210" max, fastening gypsum board to metal studding — the heavier-framing counterpart of the Drywall TEK class.

Specifications
The Gypsum TEK class covers the heavy end of board-to-steel fixing. The collected table splits it over two diameter groups: No. 6 screws with a .035"–.090" window, and No. 12 and No. 14 screws with a .089" min to .210" max window — roughly twice the metal of the Drywall TEK class — with the pairing printed as gypsum to metal studding, 2×4 or firring to steel. The two diameter groups let one line serve both the face-fixing screw and the heavier structural fixing that ties layered board through to heavier studs. As with the other special-purpose classes, the collected table prints no drill-point length; point geometry is confirmed against the framing system at quotation.

Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (Gypsum TEK Self-Drilling Screws (Heavy Gypsum to Steel)) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 10,000 pieces. Stock items run 3–7 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
Drywall TEK or Gypsum TEK for a board-to-steel job?
Measure the metal, not the board. The two classes share the application family, but their windows differ: the Drywall TEK class runs No. 6/No. 8 up to 26 gauge, while the Gypsum TEK class runs No. 6 at .035"–.090" and No. 12/No. 14 up to .210". A single 25-gauge stud with one board layer sits in either band at the light end; heavier studs, double layers or through-fixing to heavier steel behind the board push you into the No. 12/No. 14 windows. Because the printed windows overlap in the light range, the honest check is the measured metal thickness and the screw diameter your fixing pattern needs — bring both to the RFQ and the class is confirmed against the tables.
What is the MOQ and lead time for these self-drilling screws?
Minimum order quantity is 10,000 pieces per item. Stocked sizes ship in 3–7 days; non-stock diameters, lengths or finishes are quoted with a confirmed schedule. Confirm the exact schedule against quantity and size mix at quotation.
What should an RFQ for these special-purpose TEK screws state?
State the point class (Stitch, Plymetal, Plymetal with Wings, Drywall or Gypsum TEK), the screw diameter from the class table, the base material it drills into and the total thickness or gauge of the stack, head form and drive, length, finish (for example zinc plated or 410 stainless), required certificates such as a mill test report per EN 10204 3.1, and quantity per size — plus destination country.
