Metallics TP321SFC – Frequently Asked Questions
1) What driver do I need for the Metallics TP321SFC tamper-resistant screw?
It takes a spanner bit, the two-hole (snake eye) tamper-resistant drive. A Phillips, slotted, or Torx bit will not engage it, so order the matching spanner bit or driver separately if your crew does not already carry one. That drive is the point of the screw: it keeps the public out of panel covers, restroom partitions, fixture housings, and enclosure plates.
2) Does this screw sit flush with the surface or stand proud of it?
Flat head, so it sits flush when driven into a countersunk hole. If your cover plate or panel has a flat (non-countersunk) hole, the head will stand above the surface and you would want a pan or truss head instead.
3) Can I use a 1/4-20 spanner machine screw on electrical enclosures and panel covers?
That is the usual application. The TP321SFC is catalogued for electrical work, and a 1/4-20 flat head spanner machine screw is what gets specified where a cover has to be secured against casual removal but still be serviceable with the right bit. It relies on a tapped hole in the enclosure or a nut behind the panel.
4) How many Metallics TP321SFC screws come in a box?
100 pieces per box. For an MRO or facilities crew standardizing fastener hardware on tamper-resistant panel and plate covers, that is a single part number, model TP321SFC, to stock rather than loose counts.
