Metallics TP508SBC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP508SBC?
The TP508SBC is a #10 x 1/2 inch sheet metal screw with a button head and a pin-in hex (tamper resistant) drive. It ships 100 pieces to a pack.
2) What driver do I need for the pin-in hex head on these tamper resistant screws?
You need a pin-in hex (tamper proof Allen) bit, not a standard hex key. The head has a center pin that blocks a solid hex driver, so a hollow-center security hex bit in the matching size is required.
3) Why would an electrician use a tamper resistant screw instead of a standard sheet metal screw?
Tamper resistant fasteners like the TP508SBC are used where a cover or plate needs to stay put in public or unsecured areas: panel covers, device plates, enclosure lids, and fixture housings. The pin-in hex head keeps them from being backed out with common tools. If the location is not accessible to the public, a standard slotted or Phillips SMS does the same holding job at less cost.
4) Does the Metallics TP508SBC need a pre-drilled hole?
It is a sheet metal screw, so it cuts its own thread in a pilot hole in sheet metal or a pre-punched hole in an enclosure or plate. It is not a self-drilling screw, so you still need the hole first.
5) How many screws come in a pack of Metallics TP508SBC, and is the 1/2 inch length enough for a cover plate?
Each pack carries 100 screws. At 1/2 inch under the head, the length suits thin stock, cover plates and enclosure flanges, where roughly three full threads of engagement past the material is enough. For thicker assemblies you want a longer #10 SMS.
6) What is the button head profile on the TP508SBC good for?
A button head sits low and rounded above the surface rather than countersinking, so the TP508SBC mounts to flat, unprepped sheet material without needing a chamfered hole. If your plate is countersunk, you want a flat head screw instead.
