Metallics TP330SFC – Frequently Asked Questions
1) Does the Metallics TP330SFC take a standard screwdriver?
No. The TP330SFC is a spanner tamper-resistant head, so it needs a spanner (snake-eye) bit with two pins that engage the two holes in the head. A Phillips, slotted, or Torx driver will not turn it. Order the matching spanner bit with the screws if your crew does not already carry one.
2) Why would I use a tamper-resistant screw like the TP330SFC on an electrical job?
Spanner-head screws are used where a cover, plate, or enclosure in a public or shared space should not come off with a pocket screwdriver: device plates in schools, transit areas, correctional and healthcare facilities, multi-family common areas. The TP330SFC is a 10-24 x 3/8 machine screw version, so it goes into tapped holes in a box, plate, or enclosure flange rather than into drywall or wood.
3) Will a flat head 10-24 x 3/8 screw sit flush on my cover plate?
It sits flush only if the hole is countersunk. The TP330SFC has a flat head, which is designed to seat into a chamfered or countersunk hole and finish level with the surface. On a plate with flat, non-countersunk holes the head will stand slightly proud, so for those you want a pan or truss head instead.
4) Is the Metallics TP330SFC a sheet metal screw or a machine screw?
Machine screw. The MS in the TP330SFC description means machine screw, so the 10-24 thread runs the full length for a tapped hole or a nut. If you are fastening into unthreaded sheet metal, a machine screw is the wrong choice unless you tap the hole first or back it with a 10-24 nut.
5) How many screws come in a pack of Metallics TP330SFC?
Each pack of TP330SFC is 100 pieces, which is sized for a plate or cover changeout across a floor or a building rather than a single device. The screws are made in the USA.
