Metallics TP516SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP516SFC?
It's a #14 x 1 inch flat head sheet metal screw with a hex head drive that has a center pin, making it tamper resistant. They come 100 pieces to the pack, so one pack covers a fair amount of cover plate or enclosure work without reordering.
2) Do I need a special bit to drive the TP516SFC tamper resistant screws?
Yes. The head is a hex socket with a pin in the center, so a standard hex key or hex bit will not seat. You need a pin-in-hex (hex pin) driver sized to the screw. Order the bit along with the screws if you don't already keep them on the truck, otherwise you can install but not remove.
3) Are the Metallics TP516SFC screws stainless steel and can they go outdoors?
They're 18-8 stainless, which is the common 300 series austenitic grade used for general corrosion resistance. That makes them suitable for damp and exterior locations where a plain steel or zinc plated screw would rust and seize, which matters if the point of the screw is that it can still be removed years later.
4) Will a flat head tamper resistant screw sit flush in a cover plate?
Flat head means a countersunk 82 degree head, so it seats flush in a countersunk or chamfered hole. On a flat, non-countersunk plate the head will stand proud. For flush mounting in sheet steel, the hole needs to be countersunk or dimpled first.
5) Is the TP516SFC a sheet metal screw or a machine screw?
Sheet metal screw. It has a thread that forms its own mating thread in sheet steel or a pilot hole and is not meant to run into a tapped machine thread. If what you're fastening into is already tapped, a machine screw is the right part instead.
6) What are these security screws typically used for on electrical work?
A #14 x 1 inch tamper resistant stainless sheet metal screw is the fastener used where a cover needs to stay put in a public or shared space: enclosure and panel covers, device and cover plates, junction box lids, and fixture housings in schools, transit areas, multi-family common areas, and correctional or healthcare settings. The pin-in-hex head keeps anyone without the matching bit from opening it.
7) What is the manufacturer part number to order these Metallics security screws?
Order Metallics part number TP516SFC. That number covers the full 100 piece pack of #14 x 1 inch flat head hex pin stainless sheet metal screws, not a single screw.
