Metallics TP322SPC – Frequently Asked Questions
1) What driver do I need for a spanner tamper-resistant screw like the Metallics TP322SPC?
Spanner (also called snake eye) heads take a two-pin spanner bit, not a Phillips or a hex key. The TP322SPC head has two round recesses set apart on the face, and the bit's two pins have to match that spacing to turn it. Standard drivers will not engage it, which is the point of the security head, so order the matching spanner bit if you do not already have one in the kit.
2) Will a 1/4-20 x 1-1/2 machine screw work in a sheet metal enclosure without a tapped hole?
No. The TP322SPC is a machine screw, so it needs a 1/4-20 tapped hole, a nut, or a 1/4-20 threaded insert on the back side. For an untapped sheet metal hole you want a self-tapping or thread-forming screw instead. At 1-1/2 inches of length it suits stacking through a cover plus a spacer or standoff into threaded material.
3) What is the exact part number for the Metallics 1/4-20 x 1-1/2 spanner-head screw?
Order it as Metallics TP322SPC. That part number covers the 1/4-20 x 1-1/2 pan head spanner tamper-resistant machine screw in the 100 piece pack.
4) Why use a tamper-resistant screw on electrical covers instead of a standard Phillips?
A spanner head stops casual removal with the drivers anyone carries, which is why these get specified on panel covers, device plates and fixture housings in schools, transit areas, lobbies and other public spaces. The TP322SPC gives you that security head in a common 1/4-20 machine screw size, so the hole prep is the same as the standard screw you are replacing.
5) How many screws come in a box of Metallics TP322SPC?
They ship 100 pieces to the pack, so one box covers a run of panel, cover plate or fixture fastenings without reordering mid-job.
