Metallics JTEKD8V – Frequently Asked Questions

1) What thread size are these #12 self-drilling screws, and will they match my existing fasteners?
They are a #12 diameter, 14 threads per inch, UNC thread, 1 inch long, built to SAE J78-2013 for the thread form and ASME B18.6.3-2010 for dimensions. If what is already in the job is a 12-14 self-drill, these interchange.
2) Do I need to pre-drill a pilot hole before running these into sheet metal?
No. This is a Type BSD self-drilling and tapping screw, so the drill point cuts the hole and the threads tap it in one pass. Metallics cites a drill time of 2.5 seconds through a 1 mm plate. Use a steady low-to-medium speed driver and let the point do the cutting before the threads catch.
3) Is the washer on the JTEKD8V a separate loose washer or part of the head?
It is an integral washer face formed with the head, not a loose piece. Outside diameter is 0.398 to 0.432 inch with a thickness of 0.022 to 0.039 inch, which spreads bearing load over sheet metal and strut without adding a second part to handle overhead.
4) Are Metallics JTEKD8V screws suitable for outdoor or damp locations?
These are carbon steel with a zinc plating, silver in appearance. Zinc plate handles indoor and protected work fine, but it is a plated finish rather than stainless or hot-dip, so sustained exterior exposure or wet corrosive environments will eventually show rust. For those conditions specify a stainless self-drill instead.
5) How tough are these screws? Will they snap driving into heavier gauge steel?
Case hardness is Rockwell C32-40 with a minimum torsional strength of 92 lb-in, made from AISI 1016-1024 steel. That is enough to drill and tap through the rated 0.110 to 0.210 inch panel range without shearing, provided you stay within it and keep the driver square. Over-driving past seat is the usual cause of snapped heads.
6) Do these screws meet Buy American requirements for a federally funded job?
Metallics lists the JTEKD8V as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, so if your specification requires a single documented origin, request origin paperwork for the specific lot.
7) How are these packaged and what is the minimum order?
The JTEKD8V ships in a jar of 500 pieces, and 500 count is the order minimum. Figure about 5 lbs for the jar.
