Metallics JTEKD94 – Frequently Asked Questions

1) Do I need to pre-drill a pilot hole before driving these into steel?
No pilot hole. These are Type BSD self-drilling and tapping screws, meaning the point drills the hole and the threads cut their own mating thread in one operation. The manufacturer cites a drill time of about 2.5 seconds through 1 mm plate. Steady pressure and no pre-drilling is the correct technique.
2) What size driver do I need for these 5/16 indented hex head screws?
A 5/16 hex driver or nut setter. Head width measures 0.305 to 0.312 in. across the flats and 0.34 across the corners, with a head height of 0.139 to 0.155 in. It is a hex drive only, no slot or Phillips combo in the driving recess.
3) Is the washer bonded to the screw or is it a separate loose washer?
The JTEKD94 is supplied as a hex washer head screw, so the washer face is part of the assembly rather than a loose part you thread on. Washer OD runs 0.398 to 0.432 in. with a thickness of 0.022 to 0.039 in. That bearing surface is what spreads load on thin panel and keeps the head from pulling through.
4) Can I use these zinc plated self-drilling screws outdoors or in a damp location?
Material is zinc plated steel. Zinc plating handles indoor and protected applications, dry electrical rooms, strut and panel work, interior framing. It is not a stainless screw, so for exterior exposure, coastal air, or wet process areas you want a stainless self-drilling fastener instead.
5) How strong are these screws and will they snap when driven with an impact driver?
Minimum torsional strength on the JTEKD94 is 92 lb-in, with case hardness of Rockwell C32-40 on AISI 1016-1024 steel. That is enough to drill and tap steel in the stated 0.110 to 0.210 in. range, but an impact driver will overrun it easily. Drive it with a clutched screwgun or a drill set to a controlled speed and back off once the washer seats.
6) What thread pitch is a #12 self-drilling screw, and how much thread engagement do I get?
The JTEKD94 is a #12 diameter with 14 threads per inch, conforming to SAE J78-2013 for thread form and ASME B18.6.3-2010 for head dimensions. At 1-1/2 in. overall length you have plenty of shank for stacked material, but the drill point still has to clear the base metal before the threads engage, so total material stack matters as much as the base panel thickness.
7) How many Metallics JTEKD94 screws come in a jar, and is there an order minimum?
These ship in a jar with an order minimum of 100 count. Jar weight is listed at 1.32 lbs. If you are fastening a run of strut, box supports, or panel brackets, figure your screw count and order in multiples of 100.
8) Do these screws meet Buy American requirements for a federally funded job?
The JTEKD94 is flagged compliant for both ARRA and Buy American, with country of origin listed as China. On a federally funded project, pass both of those data points to your specifier, because the compliance route and the origin need to line up with the specific funding program on your job.
