Metallics TP508SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP508SFC?
It's a #10 x 1/2 inch sheet metal screw with a flat head, driven by a tamper-resistant hex pin drive, in 18-8 stainless steel. Sold 100 pieces to the box.
2) Do I need a special driver for the hex pin tamper-resistant screws on the TP508SFC?
Yes. The hex pin drive has a post in the center of the hex recess, so a standard hex/Allen key will not seat. You need a pin-in-hex security bit sized to the recess. Plan on having those bits on the truck before the install, since a standard hex set won't drive or remove them.
3) Will the TP508SFC stainless screws hold up outdoors or in a damp location?
18-8 stainless (the common 300-series austenitic grade) gives good general corrosion resistance for exterior covers, damp interiors, and coastal-adjacent work. It is not the choice for direct, continuous salt-spray immersion, where a 316 fastener is the better call.
4) Are these sheet metal screws self-drilling?
No. The TP508SFC is a plain sheet metal screw (type AB/A style point, not a self-drilling tapper), so you drill or punch a pilot hole in the sheet first and let the screw thread cut. If you need to go through gauge steel without pre-drilling, you want a self-drilling point instead.
5) What are these #10 tamper-resistant screws typically used for on electrical work?
Flat head #10 security sheet metal screws at 1/2 inch length are the standard way to lock down cover plates, enclosure and box covers, device plates, and panel trims in public or high-traffic areas where you don't want the cover coming off with a common driver. The flat head countersinks flush so nothing snags.
6) How many Metallics TP508SFC screws come in a box?
100 pieces per box, all one size (#10 x 1/2 inch). For a building standardizing on security cover plates, that is enough for roughly 25 four-screw covers per box.
