Metallics TTS21-5M – Frequently Asked Questions

1) What driver do the Metallics TTS21-5M tri-drive screws take?
The pan head on the TTS21-5M accepts three drivers: slotted, Phillips, or square. That's the point of a tri-drive head, you grab whichever bit is already in the gun or whichever screwdriver is on the truck, so panel and box work doesn't stall over a bit change.
2) What size are the Metallics TTS21-5M tapping screws?
Number 8 diameter by 1 inch long. That length suits fastening through sheet metal, device plates, and box hardware where a longer screw would bottom out or project behind the panel.
3) Are these tri-drive screws self-tapping, or do I need to drill first?
They're tapping screws, so they cut their own thread in a pilot or punched hole in sheet metal. You still want a hole sized for a number 8 tapping screw; they are not self-drilling point screws that start their own hole in solid stock.
4) Can the Metallics TTS21-5M screws be used outdoors or in a damp location?
The material is steel with zinc plating, which handles indoor and dry or occasionally damp interior work. Zinc plating is not a marine or sustained wet-location finish, so for exterior exposure or washdown areas pick a stainless or hot-dip galvanized fastener instead.
5) Are Metallics tri-drive tapping screws made in the USA?
Yes. The TTS21-5M number 8 by 1 inch tri-drive tapping screws are made in the USA, which matters on public and institutional jobs carrying domestic sourcing requirements.
6) Why choose a pan head over a flat head for electrical panel and box work?
A pan head sits on top of the surface with a broad flat bearing face, so it clamps thin sheet metal, straps, and plates without needing a countersink. If the part you're fastening is countersunk and the head has to finish flush, a pan head is the wrong choice; use a flat head there. The TTS21-5M is a pan head screw.
7) How do the TTS21-5M screws come packaged for a bulk MRO order?
Part number TTS21-5M is the 5,000-piece bulk quantity of the number 8 by 1 inch pan head tri-drive tapping screw. It's the count you'd standardize on for a shop crib or a large rough-in, rather than a small jar for a single service call.
