Metallics JTEKD9V – Frequently Asked Questions
1) What size driver or socket do I need for the Metallics JTEKD9V hex head screw?
A 3/8 inch hex driver. The indented hex washer head measures 0.367 to 0.375 inches across the flats and 0.409 across the corners, which is the standard 3/8 drive, and the drive type is hex only (no slot to cam out of). Head height runs 0.172 to 0.190 inches.
2) Does the washer head on this screw need a separate sealing washer?
No separate washer is required. The washer is integral to the head on the JTEKD9V, with an outside diameter of 0.480 to 0.520 inches and a thickness of 0.030 to 0.050 inches. That bearing surface spreads the clamp load and helps bridge slots or oversized holes in strut, hangers and panel flanges. It is a bare steel washer face, not a bonded rubber or EPDM seal, so for exterior weather sealing you would add a separate bonded washer.
3) Is a zinc plated self-drilling screw OK for outdoor or damp electrical work?
The JTEKD9V is carbon steel with a zinc finish, which is a dry-location and indoor-grade coating. It holds up in conditioned mechanical rooms, interior strut runs and panel work. For roof-mounted conduit, wet locations, coastal exposure or anywhere in contact with treated lumber, specify a 410 stainless or stainless-capped self-driller instead, since zinc plating will red-rust in those conditions.
4) Will a 3/4 inch long #14 screw be long enough for my connection?
At 3/4 inch overall length, the JTEKD9V gives you roughly a half inch of usable thread once the #3 drill point and the washer head are accounted for. That covers typical stacked-steel work: a bracket or strap into steel stud, channel, or a steel beam flange. If your combined material stack plus required thread engagement exceeds that, step up to a 1 inch or longer screw in the same series rather than relying on the point to reach through.
5) Will #14 self-drilling screws hold thread in the steel I am fastening into?
Yes, within their range. The JTEKD9V is a #14 diameter with 14 threads per inch in a UNC form, case hardened to Rockwell C32-40 from AISI 1016 - 1024 carbon steel, so the point is hard enough to cut its own thread in structural steel and keep it. Metallics notes that minimum torque values are the same for stainless and steel self-drill screws. Dimensionally it is built to ASME B18.6.3-2010.
6) Do these Metallics self-drilling screws qualify for a Buy American or federally funded project?
Metallics lists the JTEKD9V as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your contract requires a specific origin certification per lot, request documentation against the shipment you receive.
7) How are the Metallics JTEKD9V screws packaged, and what is the smallest quantity I can order?
They ship in a jar of 500 pieces, and 500 count is the order minimum. Shipping weight of the jar is 6.15 lbs.
