Metallics JTEKD2 – Frequently Asked Questions

1) How much torque can I put on a #8 self-drilling screw before it snaps?
Torsional strength on the JTEKD2 is 42 lb-in minimum, and hardness is Rockwell C32-40. That hardness is what lets the point drill without the threads giving out, but it also means the screw will shear rather than strip if you overdrive it. On an impact driver, back off the setting and stop as soon as the washer seats.
2) Can I use these on a federally funded Buy American project?
No. The Metallics JTEKD2 self-drilling screw is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. If your spec carries a domestic sourcing requirement, this fastener will not satisfy it.
3) What size driver do I need for the Metallics JTEKD2 indented hex head screw?
It takes a 1/4 inch hex driver. The head is an indented hex type measuring 0.244 to 0.25 inches across the flats, 0.272 across the corners, and 0.096 to 0.11 inches high, with a hex drive. A standard 1/4 inch magnetic nut setter in a drill or impact driver is all you need.
4) Do I need to add separate washers to these hex head self-drilling screws?
No. The washer is built into the head. It runs 0.322 to 0.348 inches outside diameter and 0.019 to 0.031 inches thick, which spreads the clamp load over thin sheet metal so the head does not pull through. Nothing else to stock or drop on the deck.
5) Will these Metallics screws hold up in a damp mechanical room or unconditioned space?
The JTEKD2 screw is steel with a zinc finish, built to the AISI 1016 to 1024 material standard. Zinc plating handles indoor and protected conditions, including mechanical rooms, plenums and equipment closets. For direct exterior exposure, salt air or constant wetting, step up to a stainless or coated exterior-rated fastener instead.
6) What thread pitch do these Metallics #8 self-drilling screws have, and will they match my existing fasteners?
18 threads per inch, cut to the SAE J78-2013 self-drilling screw standard with head dimensions to ASME B18.6.3-2010. That is the standard #8 self-drill pitch, so they thread into holes already tapped by other #8 Type BSD screws and interchange with them on repair and panel replacement work.
7) How many screws come in a jar of Metallics JTEKD2?
They ship 100 to a jar, and the jar is the order minimum. Packed weight is 0.46 lbs. The jar format keeps them together in a van bin rather than loose in a pouch, which matters when you are pulling a handful at a time across a duct run or panel install.
8) What trades actually use the Metallics JTEKD Type BSD screw?
It is aimed at electrical, plumbing, and heating and air conditioning work. Typical uses are hanging junction boxes and conduit straps to metal studs or strut, fastening duct sections and equipment housings, and mounting pipe brackets to metal surfaces. It is a metal-to-metal fastener, not a wood or masonry screw.
