Metallics TP505SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP505SFC?
It's a #8 x 3/4 inch sheet metal screw with a flat head, driven by a hex pin tamper-resistant bit, in 18-8 stainless steel. Sold 100 pieces to the box under part number TP505SFC.
2) What driver do I need for a hex pin tamper-resistant screw like the TP505SFC?
A standard hex (Allen) bit won't work. The hex socket has a pin in the center, so you need a matching pin-in-hex tamper-resistant bit sized to the screw. Plan on buying the bit with the screws if you don't already carry security bits in your kit.
3) Can the TP505SFC stainless screw be used outdoors or in damp locations?
18-8 stainless is an austenitic chromium-nickel grade with good general corrosion resistance, so these #8 x 3/4 screws hold up in damp interior and typical exterior service far better than plated carbon steel. For salt spray or pool chemical exposure, specify a 316 stainless fastener instead.
4) Will a flat head tamper-resistant screw sit flush on a cover plate?
Only if the hole is countersunk. A flat head seats into a tapered (82 degree) countersink and finishes flush with the surface. On a plate with a flat, non-countersunk hole the head will stand proud, so pick a pan or truss head instead for those.
5) Are sheet metal screws like the TP505SFC self-drilling, or do I need to pilot the hole?
These are sheet metal screws, not self-drillers, so there is no drill point on the tip. Pilot the material first, then drive. The 3/4 inch length suits sheet steel, enclosure covers, device plates, and similar thin-gauge work where the threads bite the full thickness.
6) Why would an electrical contractor spec tamper-resistant screws instead of standard ones?
They keep covers on. In schools, transit, correctional, healthcare, and any public-access area, a pin-in-hex head stops a cover, plate, or enclosure from being opened with a screwdriver or hex key out of someone's pocket. These #8 x 3/4 stainless screws come 100 to a box, which is enough to standardize a floor or a building's device plates on one security head.
