Metallics TXW121 – Frequently Asked Questions

1) Does this screw seal against water, or do I need a separate washer?
The sealing washer is already bonded to the head, so nothing extra is needed. Washer outside diameter is 0.398 to 0.432 inch with a thickness of 0.022 to 0.039 inch, and it compresses under the hex head to close the hole. That is what makes it suitable for exterior metal panel, roofing, and outdoor enclosure work.
2) Do these screws meet Buy American and ARRA requirements for a government job?
Yes. The TXW121 is flagged both Buy American compliant and ARRA compliant, with country of origin listed as United States. That covers the documentation most federally funded and public agency jobs ask for on fasteners.
3) Will the TXW121 hold up outdoors without rusting out?
It carries a zinc plus All-Weather coating rather than plain zinc, which is the finish Metallics specifies for exposed, weather-sealed applications. Paired with the bonded sealing washer, it is built for exterior panel and enclosure fastening rather than dry interior use.
4) Is the TXW121 strong enough to drive into steel without snapping the head off?
Minimum torsional strength is 92 lb-in, with a case hardness of Rockwell C32-40 and steel to AISI 1016-1024. That is the standard self-drilling screw spec range for driving into structural-gauge steel with an impact or screw gun. Keep the gun at moderate RPM and let the point cut rather than leaning on it.
5) What standards does the Metallics TXW121 screw conform to for submittal?
Dimensions are to ASME B18.6.3-2010 and threads to SAE J78-2013, with material to AISI 1016-1024. Those three are what a spec reviewer typically wants on a Type BSD self-drilling screw submittal.
6) What is the thread pitch and length on the 12-14 x 1 inch self-drilling screw?
It is a #12 diameter screw at 14 threads per inch, 1 inch long overall. With the drill point consuming part of that length, plan on roughly 1 inch of total grip through panel and substructure, which matches the 0.110 to 0.210 inch panel range it is rated for.
7) Can I use these screws to fasten electrical enclosures and strut on an exterior wall?
That is the intended use. The TXW121 is an electrical-department self-drilling screw with a bonded sealing washer, so it is commonly used to mount boxes, enclosures, straps, and panel work to metal substrates where the hole has to stay weather tight. Confirm the steel you are drilling falls in the 0.110 to 0.210 inch range.
8) How many Metallics TXW121 screws come in a pack and how are they packaged?
They ship 100 to a jar, and 100 count is the order minimum. The packed jar weighs 1.32 lbs.
