Metallics TP337SFC – Frequently Asked Questions
1) Do the TP337SFC screws need a special driver bit?
Yes. These are spanner tamper-resistant screws, which use a two-hole (snake eye) drive rather than a slot, Phillips, or Torx. You need a spanner bit sized for a #10 head to install or remove them, so budget for the bit if your crew does not already carry one.
2) Will these Metallics screws sit flush in a countersunk hole?
They will. The TP337SFC is a flat head screw, so the conical head seats down into a countersunk or dimpled hole and finishes flush with the surface. If your plate or cover has a straight-walled clearance hole with no countersink, the head will stand proud and you want a pan or round head instead.
3) Why would I use tamper-resistant screws on an electrical cover or device plate?
Spanner-drive fasteners like the Metallics TP337SFC are specified where you do not want the public opening the enclosure: wall plates and device covers in schools, transit areas, correctional facilities, lobbies, and other high-traffic or vandal-prone spaces. A common driver will not engage the head, so access is limited to whoever carries the spanner bit. Property managers and MRO buyers typically standardize on one drive style across a building so one bit covers every opening.
4) How many Metallics TP337SFC screws come in a pack?
One hundred pieces per pack, ordered under part number TP337SFC. That quantity suits a plate-by-plate retrofit across a floor or a stocked MRO bin rather than a one-off repair.
5) Are the TP337SFC machine screws made of steel?
Yes, they are machine screws in steel, US made. Steel gives you the strength for a threaded cover or plate fastening, but it is not a stainless or coated marine fastener, so for wet, washdown, or exterior coastal locations choose a stainless tamper-resistant screw instead.
