Metallics JTEKD3V – Frequently Asked Questions
1) How thick a metal panel can the Metallics JTEKD3V #10 self-drilling screw go through?
The #2 drill point on the JTEKD3V is rated for panel thickness of 0.035 to 0.110 inch. That covers typical light-gauge steel studs, strut, hat channel and sheet metal. Thicker structural steel needs a heavier drill point, not this one.
2) Do I need to pre-drill a pilot hole for these #10 x 3/4 in. hex head screws?
No. The JTEKD3V is a Type BSD self-drilling and tapping screw, so the drill point cuts its own hole and the 16 threads per inch UNC thread taps it in one pass. No pilot hole, no separate tap.
3) Does the washer on this screw seal, or is it just a bearing surface?
It is an integral steel washer head, not a sealing washer. Washer OD runs 0.384 to 0.414 inch with a thickness of 0.019 to 0.031 inch, which spreads clamp load over sheet metal and keeps the head from pulling through thin panel. For a weathertight roof or siding application you want a bonded EPDM-washer screw instead.
4) Are these zinc-plated screws okay for outdoor or damp electrical work?
The JTEKD3V is zinc-plated carbon steel (AISI 1016-1024), which is a dry-interior finish. Use it indoors on strut, raceway, boxes and light-gauge framing. Outdoors, in corrosive or coastal conditions, or in direct contact with treated lumber, go to a stainless or coated self-drilling screw.
5) Will the Metallics JTEKD3V snap off in an impact driver?
Torsional strength is 61 lb-in minimum, with a case hardness of Rockwell C32-40. Metallics notes that minimum torques are the same for stainless and steel self-drill screws and drill time is 2.5 seconds through a 1 mm plate. Keep the driver speed up and the pressure steady; backing off pressure or stalling the point is what shears a drill screw, not the torque rating.
6) Do these screws meet Buy American requirements for a public job?
Metallics lists the JTEKD3V as both ARRA compliant and Buy American compliant. Country of origin is listed as multiple. Dimensionally it is built to ASME B18.6.3-2010 with threads to SAE J78-2013, which is the spec language most government and institutional submittals ask for on self-drilling screws.
7) Is a 3/4 inch length long enough to fasten strut or a box to a metal stud?
At 3/4 inch overall with a 0.035 to 0.110 inch panel thickness rating, there is plenty of thread left to engage past light-gauge steel. Where it falls short is stacked material: if your combined grip (channel plus flange plus a bracket) pushes the drilled layer beyond 0.110 inch, step up to a longer screw with a heavier drill point.
8) How are these #10 x 3/4 in. drill screws packaged, and is there a minimum order?
They ship in a jar of 500, and 500 count is the order minimum. The packed jar weighs 2.7 lbs. Metallics notes other sizes and quantities are available by request.
