Metallics TEK11M – Frequently Asked Questions

1) What size driver or socket do I need for the Metallics TEK11M hex head self-drilling screw?
A 3/8 inch hex driver. The TEK11M has an indented hex washer head with a hex drive, and the head width measures 0.367 to 0.375 inch across the flats, with 0.409 inch across the corners. A standard 3/8 inch magnetic nut setter in a screw gun seats it fine.
2) Do I need to pre-drill a pilot hole for these screws?
No. The TEK11M is a Type BSD self-drilling and tapping screw, so the drill point cuts its own hole and the thread taps it in one pass. Clamp the parts tight together first, since any gap lets the top layer spin up on the thread.
3) Will these screws meet a Buy American or ARRA requirement on a federal job?
Metallics lists the TEK11M as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, so if your specifier requires a single documented origin per lot, confirm the origin on the lot you receive.
4) Is a #14 x 1-1/2 inch TEK screw long enough to fasten through two layers of steel plus a bracket?
At 1-1/2 inches of overall length with 14 threads per inch in a UNC coarse thread, the TEK11M carries plenty of grip for stacked steel, provided the point can clear the back face of the last layer. Self-drill screws need the drill point to fully exit before the threads begin tapping, so subtract roughly the point length from your 1-1/2 inches when figuring usable grip against your total stack thickness.
5) Is the washer built into the head or a separate loose washer I have to add?
It is part of the head. The TEK11M uses an indented hex washer head, so the bearing surface is formed into the screw, 0.480 to 0.520 inch outside diameter and 0.030 to 0.050 inch thick. Nothing loose to handle, and no separate washer to order. Note it is a plain steel washer face, not a bonded rubber or EPDM seal, so this is not a roofing or weather-seal screw.
6) Are these zinc screws OK for outdoor or damp use?
The TEK11M is carbon steel with a zinc finish, which is a mild indoor corrosion coating. It holds up in dry interior work (strut, metal stud, panel and enclosure mounting) but it is not a marine or sustained-exposure finish. For wet or exterior conditions, specify a stainless self-drill screw instead.
7) What standards are these self-drilling screws manufactured to?
Three apply to the TEK11M: dimensions to ASME B18.6.3-2010, threads to SAE J78-2013, and steel to AISI 1016-1024. Case hardness is Rockwell C32-40. That package is what a submittal reviewer usually wants to see on a self-drill screw. Worth knowing for anyone speccing small diameters: SAE J78 does not cover #7 diameter drill screws.
8) Are the Metallics TEK11M screws sold individually or only by the box?
They ship as a box with a 1000 piece minimum. So this is a bulk-quantity item for a crew or a stockroom, not a handful for one device. Box weight is listed at 17.5 lbs.
9) How much clearance do I need under the head of this screw for the hex washer to seat flat?
Allow for a head height of 0.172 to 0.190 inch plus a washer face up to 0.520 inch in diameter on the TEK11M. If you are driving into a recess, a channel leg, or next to a raised flange, that 0.520 inch footprint is the number to check. Tight spots next to a return usually call for a pan or truss head instead of a hex washer.
