Metallics TP514SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP514SFC?
TP514SFC is a #14 x 1/2 inch sheet metal screw with a flat head and a hex pin tamper-resistant drive, made from 18-8 stainless steel and packed 100 to a box. The short 1/2 inch length makes it a screw for fastening into sheet metal, strap, or thin substrate rather than deep anchoring.
2) Do I need a special bit to install the TP514SFC tamper-resistant screws?
Yes. The hex pin (pin-in-hex) drive on these #14 screws has a post in the center of the recess, so a standard hex key or ordinary hex bit will not seat. You need a matching pin-in-hex security bit or driver, which is not included with the 100-piece box, so order the bit separately if you don't already carry one.
3) Are 18-8 stainless tamper-resistant screws like the TP514SFC okay for outdoor or damp locations?
18-8 stainless (the 300-series austenitic grade used in these #14 x 1/2 inch screws) holds up far better than plain or zinc-plated steel in wet and outdoor exposure, which is why it gets specified for exterior enclosures, covers, and coastal-adjacent work. It is not the choice for constant salt immersion, where a 316 fastener is the step up.
4) Why use a flat head screw instead of a pan head on an electrical cover plate?
The flat head on the TP514SFC sits flush when driven into a countersunk or chamfered hole, so nothing protrudes above the surface to snag or be gripped with pliers. Combined with the hex pin drive, that is the usual pick for covers, enclosure doors, and public-facing plates where you want the fastener both low-profile and hard to back out. A pan head stands proud of the surface and defeats that.
5) Will a #14 x 1/2 inch sheet metal screw hold in drywall or wood framing?
No, that is the wrong application. A #14 x 1/2 inch SMS has sharp, widely spaced sheet metal threads and only a half inch of usable length, so it is meant to thread into metal or a thin panel. For drywall you need an anchor, and for framing you need a longer wood or construction screw.
6) Does the Metallics TP514SFC come as a single screw or in a box?
These ship as a 100-piece pack under one part number, TP514SFC. That is a bulk count sized for an MRO shelf or a crew doing repeat cover-plate and enclosure work, not a single-fastener purchase.
