Metallics TP528SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP528SFC?
It's a #12 x 3/4 inch sheet metal screw with a flat head, made from 18-8 stainless steel, and it ships 100 pieces to the box. The head takes a hex pin tamper-resistant driver, so it needs a hex bit with a center hole rather than a standard Allen key.
2) Will a regular hex key or Allen wrench drive these tamper-resistant screws?
No. The TP528SFC uses a hex pin (pin-in-hex) head, which has a raised post in the center of the recess. A solid Allen key bottoms out on that pin and won't seat. You need a pin-in-hex security bit in the matching size, so order drivers along with the screws if your crew doesn't already carry security bits.
3) Are 18-8 stainless screws like the Metallics TP528SFC okay for outdoor or damp locations?
18-8 stainless (the common 300-series austenitic grade) handles exterior and wet-location duty far better than plated carbon steel, which is why it gets specified for outdoor enclosures, covers and vandal-resistant plates. It is not the right pick for direct saltwater immersion or heavy chloride exposure, where a 316 stainless fastener is the usual call.
4) Do I need to pre-drill for a #12 x 3/4 sheet metal screw, or will it self-tap?
A sheet metal screw forms its own thread but does not drill its own hole, so a pilot is required in anything but thin, soft sheet. The TP528SFC's #12 x 3/4 body means your usable grip is under 3/4 inch once the flat head countersinks flush, so plan the pilot depth accordingly in the material you're fastening to.
5) Why a flat head on a security screw, and does it sit flush?
The flat head is designed to countersink, so the screw finishes level with the surface. On a tamper-resistant application that matters twice over: a flush pin-in-hex head gives pliers and vise grips nothing to bite on, which is the whole point of specifying security hardware on exposed covers and public-area plates. The mating hole has to be countersunk or factory-formed for a flat head to seat properly.
6) How many Metallics TP528SFC screws come in a box?
100 pieces per box, all one configuration: #12 x 3/4, flat head, hex pin, 18-8 stainless, ordered under part number TP528SFC. There are no finish or length options to pick on this item, so quantity is the only decision.
