Metallics TEKD125M – Frequently Asked Questions

1) Can I buy the Metallics TEKD125M screws in a small quantity, or is it a bulk box only?
These ship as a bulk box with a 5,000 piece order minimum. The box runs 29.65 lbs. If you need a count for a single panel or a service truck, this is a stocking quantity, not a handful.
2) Do I need to pre-drill before running these screws into steel?
No pilot hole. The TEKD125M is a Type BSD self-drilling and tapping screw, so the point drills the hole and the thread taps it in one pass, as long as the steel falls in the 0.110 to 0.175 inch range the #3 point is rated for. Use a clutch or depth-sensitive gun so the washer seats without stripping the tapped thread.
3) Does the TEKD125M screw come with a washer, or do I buy those separately?
The washer is integral to the head, so nothing extra to order. The bonded washer runs 0.384 to 0.414 inches outside diameter and 0.019 to 0.031 inches thick, which spreads bearing on sheet metal, strut, and bracket flanges so the head does not pull through thin stock.
4) Are these Metallics TEK screws acceptable on a federally funded or Buy American job?
The TEKD125M is flagged both ARRA compliant and Buy American compliant in the manufacturer record, which is what a government, school, or transit spec typically asks for on fasteners. Country of origin is listed as multiple.
5) What standards do these #10 self-drilling tapping screws meet?
Threads are to SAE J78-2013 and head dimensions to ASME B18.6.3-2010, with steel per AISI 1016-1024 case hardened to Rockwell C32-40. Minimum torsional strength is 61 lb-in. That combination is what lets the point drill hardened sheet without the shank twisting off.
6) Will zinc plated TEK screws hold up outdoors or in a damp mechanical room?
Finish is zinc plated steel, which suits dry interior work, panel boards, strut, duct, and enclosed mechanical spaces. For exterior exposure, roof work, or washdown areas, specify a stainless or coated self-drilling screw instead; plain zinc will rust in standing moisture.
7) What thread count and length are the Metallics TEKD125M screws?
A #10 diameter screw, 3/4 inch long, 16 threads per inch, with a drill point rather than a gimlet point. The 3/4 inch length gives enough thread past a 0.110 to 0.175 inch panel to engage fully without a long tail behind the work.
