Metallics TP605SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP605SFC?
It's a #8 x 3/4 inch sheet metal screw with a flat head and a star (Torx-style) drive with a center pin for tamper resistance, made from 18-8 stainless steel. Sold 100 pieces to a box, part number TP605SFC.
2) Do I need a special bit to install the TP605SFC tamper-resistant screws?
Yes. The star drive on these #8 screws has a pin in the center of the recess, so a standard Torx bit will not seat. You need a pin-in star (tamper-resistant Torx) bit of the matching size, which is a separate purchase, not included with the 100-piece box.
3) Are these stainless screws okay for outdoor or damp locations?
18-8 stainless is an austenitic chromium-nickel grade that resists general atmospheric and moisture corrosion, so these #8 x 3/4 screws hold up in damp and exterior-exposed locations better than plated carbon steel. For coastal salt-spray exposure, 316 stainless is the more corrosion-resistant choice.
4) Can I use these for tamper-resistant cover plates in public or institutional spaces?
That's the point of the pin-in star drive. For schools, transit facilities, correctional and other high-traffic public areas, these 18-8 stainless #8 x 3/4 screws let maintenance staff with the right bit open a cover while deterring casual removal with a common screwdriver or standard Torx driver. The 100-piece box is enough to standardize across a run of devices or enclosures.
5) Does the flat head on these screws sit flush, or does it stand proud?
Flat head means a countersunk 82-degree head profile, so it seats flush with the surface when the hole is countersunk or the material is a punched/dimpled sheet. If the mounting hole is a plain drilled hole in flat stock, the head will stand proud; use a pan or truss head screw instead where you can't countersink.
6) Do these sheet metal screws cut their own threads, or do I need to tap the hole?
Sheet metal screws form their own thread as they drive, so no tapping is needed, but they are not self-drilling. Drill a correctly sized pilot hole for the #8 diameter in sheet steel or aluminum first, then drive the screw.
