Metallics TP501SBC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP501SBC?
The TP501SBC is a #6 x 3/4 inch sheet metal screw with a button head and a hex socket drive that has a center pin, which makes it tamper resistant. It's 18-8 stainless steel and comes 100 pieces to the pack.
2) Do I need a special driver for these tamper resistant pin hex screws?
Yes. The button head on the TP501SBC takes a hex socket with a pin in the center, so a standard hex (Allen) key or bit will not seat. You need a pin-in-hex bit in the matching size, which has a hole bored down the center to clear the pin. Order the bits with the screws if your crew doesn't already carry them.
3) Will 18-8 stainless screws hold up outdoors or in a damp location?
18-8 stainless (the 300 series austenitic grade used on the TP501SBC) is corrosion resistant and is the usual choice for exterior, washdown, and coastal-adjacent work where a plated carbon steel screw would rust. It is not hardened like a carbon steel self-tapper, so don't overtorque it into heavy gauge metal.
4) What are tamper resistant sheet metal screws like the Metallics TP501SBC used for on electrical work?
They're the fastener you use when you don't want the public opening something: cover plates, enclosure and junction box covers, panel trims, fixture housings, and device plates in schools, transit, detention, and public restrooms. A #6 x 3/4 length suits thin sheet metal covers and light enclosure work rather than structural attachment.
5) Is the Metallics TP501SBC a self-tapping screw or does it need a tapped hole?
It's an SMS (sheet metal screw), so the thread is designed to form its own mating thread in a pilot-drilled hole in sheet metal. You still drill a pilot sized to the screw's root diameter; it does not need a pre-tapped hole and it is not a machine screw, so it won't thread into an existing tapped 6-32 hole.
6) Is a button head the right choice, or should I use a flat head screw for the cover plate?
The TP501SBC has a button head, which sits proud of the surface on a low dome and seats on a flat hole, not a countersink. If your cover plate is countersunk and the fastener has to finish flush, a button head is the wrong profile and you want a flat (countersunk) head tamper resistant screw instead.
7) Does the Metallics TP501SBC come in a box of 100 or can I buy a single screw?
The TP501SBC is packaged 100 pieces per unit, so it's bought as a pack rather than loose. For standardizing a building on one tamper resistant fastener that works out well, you get one driver and one box covering a lot of cover plates.
