Metallics TEKD25M – Frequently Asked Questions

1) How thick a steel panel can the Metallics TEKD25M #8 self-drilling screw drill through?
The #2 drill point on the TEKD25M handles panel thickness from 0.035 to 0.100 inch. That covers typical light-gauge steel studs, strut channel covers, and sheet metal enclosures. Go thicker than 0.100 inch and the point burns before it penetrates; you need a higher drill point number for that.
2) Is this screw suitable for a Buy American or ARRA-funded electrical job?
Metallics lists the TEKD25M as both Buy American compliant and ARRA compliant, which is what a government, school, or healthcare procurement file usually needs on fastener line items. Country of origin is recorded as multiple.
3) What size driver or nut setter do I need for the TEKD25M hex head screw?
It takes a 1/4 inch hex nut setter. The indented hex head measures 0.244 to 0.25 inch across the flats and 0.272 across the corners, with a head height of 0.096 to 0.11 inch, so a standard 1/4 inch magnetic driver seats fully.
4) Does the TEKD25M screw come with a washer built in, or do I order washers separately?
The washer is integral to the head, so nothing extra to order. Washer OD runs 0.322 to 0.348 inch with a thickness of 0.019 to 0.031 inch, which spreads bearing load on thin sheet and helps hold straps, clips, and box flanges without pulling through.
5) What standards does the Metallics TEKD25M self-drilling screw meet?
Dimensions follow ASME B18.6.3-2010 and the thread conforms to SAE J78-2013. Material is AISI 1016-1024 steel, case hardened to Rockwell C32-40, with 42 lb-in minimum torsional strength. Note that SAE J78 does not cover #7 diameter drill screws, so a submittal calling out that diameter will not reference it.
6) Can I use these zinc-plated TEK screws outdoors or in a damp location?
Finish is zinc plating over carbon steel, which is a mild indoor corrosion coating. It holds up in dry interior electrical work, conditioned mechanical rooms, and ceiling plenums. For exterior exposure, washdown areas, or coastal sites, specify a stainless self-drilling screw instead.
7) What thread count is the #8 x 3/4 TEKD25M, and will it hold in light-gauge steel stud?
18 threads per inch on a #8 diameter, 3/4 inch long shank. That pitch is the standard self-tapping thread for sheet steel in the 0.035 to 0.100 inch range, and the point drills its own pilot, so no pre-drilling on a steel stud or strut.
8) How are the TEKD25M screws packaged and what is the minimum order?
They ship boxed with a 5,000 piece order minimum, a bulk quantity sized for ongoing MRO stock or a full build-out rather than a single service call. Box weight is listed at 20.35 lbs.
9) How long does a #2 point TEK screw take to drill through sheet steel?
Metallics cites roughly 2.5 seconds of drill time through a 1 mm thick plate. Let the point cut at steady pressure before the threads engage; rushing it work-hardens the hole and can shear the screw, which is rated to 42 lb-in minimum torsional strength.
