Metallics TP121SFC – Frequently Asked Questions
1) What tool do I need to drive the TP121SFC hex pin screw?
A hex pin drive (pin-in-hex) bit. The recess has a post in the center, so a standard hex key or Allen wrench will not seat. You need the matching tamper-resistant pin-in-hex driver for the 1/4-20 size, which is why these are used where you do not want the fastener backed out with common tools.
2) How many screws come in a pack of Metallics TP121SFC?
100 pieces per pack. For panel, enclosure, or fixture work where every cover screw needs to be tamper resistant, that is enough to do a batch of openings off one box rather than ordering per unit.
3) Will a flat head tamper screw like the TP121SFC sit flush on my cover plate?
Only if the hole is countersunk. The TP121SFC is a flat head, meaning a conical seat that sits flush in a chamfered or countersunk hole. On a flat drilled hole with no countersink the head will stand proud, and on thin sheet you would want a pan or truss head instead.
4) Is the TP121SFC a machine screw or a self-tapping screw?
A machine screw. It has uniform 1/4-20 machine threads and no drill point, so it needs a pre-tapped 1/4-20 hole or a nut behind the work. If you are fastening into unthreaded sheet metal, use a self-drilling or sheet metal screw instead of this one.
5) What part number do I order for the Metallics 1/4-20 x 2 inch tamper-resistant flat head screw?
Metallics part number TP121SFC covers the 1/4-20 x 2 inch flat head hex pin tamper-resistant machine screw, supplied 100 to a pack.
