Metallics TP504SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP504SFC?
The TP504SFC is a #8 x 1/2 inch sheet metal screw with a flat head and a hex pin tamper-resistant drive, made from 18-8 stainless steel. It ships 100 pieces to a pack.
2) Do I need a special bit to install the TP504SFC tamper-resistant screws?
Yes. The hex pin (pin-in-hex) drive on the TP504SFC has a post in the center of the recess, so a standard hex key or Allen bit will not seat. You need a pin-in-hex driver bit sized for a #8 screw. Plan on having that bit on the truck before the job, since nothing in a standard bit set will turn it.
3) Are these stainless screws OK for outdoor or damp locations?
18-8 stainless, the grade used on the TP504SFC, is the common austenitic stainless (roughly 18% chromium, 8% nickel) and holds up in wet and outdoor service far better than plated carbon steel. It is not the choice for constant salt spray, where 316 stainless is the usual step up.
4) Will a flat head screw sit flush, or do I need a countersunk hole?
Flat head means a conical underside that seats flush only in a countersunk or dimpled hole. On sheet metal or a flat plate without a countersink, the head will stand proud. If you want a screw that sits on the surface, you need a pan or hex washer head instead of the TP504SFC.
5) What is the TP504SFC tamper-resistant screw typically used for in electrical work?
It is an electrical-department fastener, used where a cover, plate, enclosure or device needs to be closed up so the public cannot open it with common tools. The 1/2 inch length suits thin sheet metal and cover plates rather than thick assemblies, and the sheet metal thread cuts its own hold in unthreaded metal.
6) How many screws come in a pack of Metallics TP504SFC?
One hundred pieces per pack. For a security-screw item that is typically more than a single job needs, so it covers a run of cover plates or a fleet of enclosures standardized on the same pin-in-hex drive and one bit.
