Metallics JTEKD25 – Frequently Asked Questions

1) How thick a metal panel can the Metallics JTEKD25 self-drilling screw go through?
The JTEKD25 is rated for panel thickness of 0.035 to 0.090 inches, which covers typical sheet metal gauges found in duct, enclosures, and strut work. Below 0.035 the screw can strip rather than tap; above 0.090 you need a heavier drill point than the #2 point on this screw.
2) Do I need to pre-drill a pilot hole for these hex head screws?
No pilot hole. The JTEKD25 is a Type BSD self-drilling and tapping screw with a drill point, so it cuts its own hole and forms the thread in one pass within its 0.035 to 0.090 inch panel range.
3) Can I use these screws on a Buy American or ARRA funded project?
No. The JTEKD25 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For federally funded work carrying domestic sourcing requirements you will need a domestically produced self-drilling screw instead.
4) What size driver or socket do these 1/4 indented hex head screws take?
Hex drive with a head width of 0.244 to 0.250 inches, so a 1/4 inch hex driver or magnetic nutsetter in a drill or impact driver is what you want. Width across corners is 0.272 inches, so a 1/4 inch socket seats fully on the flats.
5) Is the washer built into the screw or is it a separate loose washer?
The washer is part of the head. It is an indented hex washer head with a washer outside diameter of 0.302 to 0.328 inches and a washer thickness of 0.015 to 0.025 inches, so it spreads bearing load over the sheet without a separate piece to handle overhead.
6) Is a zinc plated steel self-drilling screw okay outdoors or in a wet location?
Zinc plated carbon steel is a dry, interior-duty finish. The JTEKD25 is steel with a zinc finish, built to AISI 1016-1024 material, which is fine for indoor electrical, plumbing, and HVAC work but will corrode in exterior, coastal, or washdown locations. Use a stainless self-drilling screw where moisture is constant.
7) Will these screws snap if I run them with an impact driver?
The JTEKD25 carries a 24 lb-in minimum torsional strength and the shank is heat treated to Rockwell C32-40. That is enough for driving into 0.035 to 0.090 inch sheet, but an impact driver will overdrive a #6 screw easily. Set a clutch or use a depth-sensitive screwgun and stop once the washer head seats.
8) What thread pitch and standard do the Metallics JTEKD screws follow?
20 threads per inch on a #6 diameter, 1/2 inch long screw, made to SAE J78-2013 for the thread and ASME B18.6.3-2010 for dimensions. If a submittal or spec sheet calls out those two standards for sheet metal self-drillers, this fastener meets the callout.
9) Will a 1/2 inch long screw be long enough to hold two layers of sheet metal together?
Usually yes. At 1/2 inch of length with a #2 drill point, the JTEKD25 has enough thread past the point to engage sheet in the 0.035 to 0.090 inch range, including two thin layers clamped tight. Where total stack-up gets near or past 0.090 inches, step up to a longer screw with a larger drill point.
10) How are the Metallics JTEKD25 screws packaged and what is the minimum order?
They ship in a jar, 100 pieces minimum, at 0.32 lbs. Handy for a van stock or a job box rather than buying a bulk box you will not finish.
11) How low profile is the head on these indented hex washer head screws?
Head height runs 0.08 to 0.093 inches, so the screw sits close to the panel. That matters when a cover, plate, or gasket has to lay over the fastener after it is driven.
