Metallics JTEKD63 – Frequently Asked Questions

1) What size driver or socket do I need for these 1/4 inch indented hex head screws?
A 1/4 inch hex driver. The indented hex head measures 0.244 to 0.25 inch across the flats, with 0.272 inch across the corners, so a standard 1/4 inch magnetic nut setter in an impact or screwgun seats it correctly. There is no cross or square recess, so drive is hex only.
2) Does the JTEKD63 come with a washer built into the head, and how wide does it seat?
The washer is integral to the head, with an outside diameter of 0.302 to 0.328 inch and a thickness of 0.015 to 0.025 inch. That bearing surface spreads load over slightly oversized or slotted holes in strap, clip and bracket work, so you do not need to add a separate flat washer.
3) Will a #6 x 3/4 inch self-drilling screw hold through two layers of sheet metal?
At 3/4 inch overall length with 20 threads per inch, the JTEKD63 has enough shank to drill and tap through stacked light-gauge sheet so long as the combined thickness stays inside the 0.035 to 0.090 inch panel range. Past that, step up to a longer screw with a heavier drill point.
4) How much torque can these screws take before they snap in an impact driver?
Minimum torsional strength is 24 lb-in, with case hardness at Rockwell C32-40. That is enough for driving into light-gauge steel, but an impact driver set to full power will twist the head off a #6 shank. Drive it and stop at seat; do not over-run it.
5) Are zinc plated steel self-drilling screws OK for outdoor or damp locations?
The JTEKD63 is zinc plated carbon steel, which is a dry indoor interior finish. For exterior, wet or corrosive locations you want a stainless or coated exterior-rated drill screw instead, since zinc plating on carbon steel will rust out.
6) What standards do these Metallics drill screws conform to?
Threads follow SAE J78 - 2013 and head dimensions follow ASME B18.6.3-2010, with the steel to AISI 1016 - 1024. Those are the usual references a spec or submittal asks for on Type BSD self-drilling and tapping screws.
7) Do these screws meet Buy American or ARRA requirements for a government job?
The JTEKD63 is flagged compliant for both ARRA and Buy American, with country of origin listed as China. On federally funded work, confirm which clause your contract invokes, because the two have different domestic content tests.
8) How are these sold, loose or in a jar, and is there a minimum order?
They ship in a jar, with a minimum order of 100 count. The packed jar weighs 0.38 lbs.
9) Will the hex head sit low enough to run strap or a device over it?
Head height on the JTEKD63 runs 0.08 to 0.093 inch above the washer face, so it is a low profile seat for mounting straps, clips and brackets where a tall hex head would interfere. It is still a raised head, not a flush or pan head, so anything that must sit perfectly flat needs a countersunk screw.
