Metallics TP531SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP531SFC?
It's a #12 x 1-1/2 inch sheet metal screw with a flat head and a hex pin tamper-resistant drive, in 18-8 stainless, sold 100 to a pack. The flat head means it needs a countersunk or dimpled hole if you want the head sitting flush with the surface.
2) What driver do I need for a hex pin tamper-resistant screw like the TP531SFC?
A pin-in-hex (tamper-resistant hex) bit or key, not a standard Allen wrench. The screw has a post in the center of the hex recess, so a solid hex bit won't seat. Order the matching pin-in-hex bits with the screws if your crew doesn't already carry a security bit set, since no driver is included with the 100-piece pack.
3) Are these screws OK for outdoor or damp-location electrical work?
The TP531SFC is 18-8 stainless, which is the usual choice for exterior and damp-location mounting where a plain or zinc-plated screw would rust out. Standard caution applies on corrosion: stainless resists it well but is not immune in coastal or chemically aggressive settings.
4) Will a #12 x 1-1/2 sheet metal screw work for mounting enclosures and covers to metal studs or strut?
That's the typical use. Sheet metal threads are a coarse, full-length thread meant to cut into sheet steel, and the 1-1/2 inch length covers a cover plus a fair bit of standoff. You need a pre-drilled pilot hole sized for a #12 in your gauge of steel; these are not self-drilling, so there's no point on them to make their own hole.
5) Why use a tamper-resistant screw instead of a standard Phillips on electrical covers?
Security. Pin-in-hex heads keep covers, enclosures and fixture trims in public corridors, school hallways, transit spaces and multi-family common areas from being opened with a screwdriver out of someone's pocket. For back-of-house panels nobody can reach, a standard drive is faster to install and cheaper. Specify tamper-resistant only where the public can touch the hardware.
6) How many screws come in a pack of Metallics TP531SFC?
100 pieces per pack, all one size (#12 x 1-1/2 inch). If you're standardizing a facility on tamper-resistant hardware, buying by the hundred keeps one bit type and one screw length on the truck instead of a mixed bag.
7) What is the exact part number to order these stainless tamper-proof screws?
Metallics part number TP531SFC. That single MPN covers the whole item: #12 x 1-1/2 inch flat head, pin-in-hex tamper-resistant, 18-8 stainless sheet metal screw, 100 per pack. There are no finish or size options to pick underneath it.
