Metallics TP308SFC – Frequently Asked Questions
1) Will an 8-32 screw fit the mounting holes on a standard wiring device or outlet box?
No. Standard wiring devices, cover plates and box mounting ears in the US are tapped 6-32, so an 8-32 screw will not thread into them. The TP308SFC is an 8-32, 1 inch flat head machine screw for 8-32 tapped holes. If you need device or plaster-ring screws, order 6-32.
2) What driver do I need for the spanner head on the Metallics TP308SFC?
A spanner bit, also called a snake-eye or two-hole bit, sized for a #8 head. The TP308SFC uses a tamper resistant spanner drive, so no Phillips, slotted, or Torx bit will turn it. Buy the bit with the screws if your techs do not already carry one, otherwise the fasteners cannot be installed or removed in the field.
3) Why would I specify a tamper resistant screw instead of a standard Phillips machine screw?
Tamper resistant spanner heads are used where the public can reach the hardware, think school and transit station cover plates, detention and healthcare rooms, parking structures, and exterior enclosures. A standard Phillips comes off with a tool anyone owns; the spanner drive on the TP308SFC needs a two-hole bit most people do not carry. Functionally it is still an ordinary 8-32 x 1 flat head machine screw, so it threads into the same 8-32 tapped holes.
4) Does the flat head on this 8-32 tamper resistant screw sit flush?
Yes, the TP308SFC is a flat head, which seats flush in a countersunk hole. The mating part needs a countersink or a chamfered clearance hole; drop it into a plain drilled hole and the head will stand proud. If you need the head to sit on top of the surface, a flat head is the wrong style.
5) How many screws come in a pack of Metallics TP308SFC?
100 pieces per pack. That is a bulk count aimed at crews doing repeat work, so for a single device or enclosure you will have plenty left over, and for a full floor of tamper resistant plates you may want multiple packs.
6) What is the exact part number to order the Metallics 8-32 x 1 spanner flat head screw?
Metallics part number TP308SFC. Spelled out, that is an 8-32 x 1 inch flat head spanner tamper resistant machine screw, sold 100 to a pack.
