Metallics TP319SPC – Frequently Asked Questions
1) What driver do I need for a spanner head screw like the Metallics TP319SPC?
Spanner (also called snake eye) heads take a two-pin spanner bit, not a Phillips or a hex key. The TP319SPC is a spanner tamper resistant screw, so plan on having the matching two-pin driver on the truck before you head out. A standard screwdriver will not engage the two holes in the head.
2) Can I use a 1/4-20 x 3/4 machine screw in sheet metal with no tapped hole?
Not on its own. The TP319SPC is a machine screw, so it needs a 1/4-20 tapped hole, a nut, or a threaded insert behind the material. For bare sheet metal with only a pilot hole you want a self-tapping or sheet metal screw instead, or tap the hole to 1/4-20 first.
3) Will these tamper resistant screws keep tenants out of an electrical enclosure or fixture cover?
That is what they are for. The spanner head on the TP319SPC cannot be turned with any common screwdriver or bit, so covers, panels, and fixture trims secured with them take a special two-pin driver to open. Property managers and MRO crews use them on public-area and tenant-accessible devices where a standard Phillips cover invites tampering.
4) Are the Metallics TP319SPC screws made in the USA?
Yes, the TP319SPC is a USA-made spanner tamper resistant machine screw. That matters on government, institutional, and some utility jobs where domestic-sourcing language sits in the spec.
5) How many screws come in a pack of Metallics TP319SPC?
They come 100 pieces to a pack, which is sized for standardizing a run of enclosures or fixture covers across a building rather than a single repair. If you are keying one facility to tamper resistant hardware, one pack covers a lot of openings.
6) What is the Metallics part number for the 1/4-20 x 3/4 spanner tamper resistant pan head screw?
TP319SPC is the Metallics part number, covering the 1/4-20 x 3/4 pan head spanner tamper resistant machine screw in a 100-piece pack. Order by that number to get the spanner drive rather than a standard Phillips pan head of the same thread and length.
