Metallics TP144SFC – Frequently Asked Questions
1) What thread size and length is the Metallics TP144SFC tamper-resistant screw?
The TP144SFC is a 3/8-16 x 2 inch machine screw. The 3/8-16 thread is the standard UNC coarse pitch for 3/8 inch diameter, so it mates with 3/8-16 tapped holes and standard 3/8-16 nuts. Length is 2 inches, and it ships 100 pieces to the pack.
2) What kind of driver do I need for the Metallics TP144SFC hex pin screw?
It takes a pin-in-hex (hex pin) security bit, not a standard hex key. The recess has a center pin that blocks an ordinary Allen wrench, so a matching pin-in-hex driver sized for a 3/8-16 screw head is required. Order the bit with the screws if your crew does not already carry security bits.
3) Is the TP144SFC screw a flat head that will sit flush?
Yes, it is a flat head (FH) screw, so it seats flush in a countersunk hole. The hole has to be chamfered for a flat head; in a flat untapered hole the head will stand proud and the tamper-resistant head will be easier to attack with pliers.
4) Why use a tamper-resistant machine screw instead of a standard hex or Phillips screw?
Tamper-resistant heads like the pin-in-hex on the Metallics TP144SFC are used where the public can reach the fastener: electrical cover plates, enclosures, grilles, fixtures in schools, transit, and multi-family common areas. The pin in the recess means nothing in a normal tool pouch will back it out. If the fastener is behind a locked door or inside a panel, a plain 3/8-16 machine screw does the same clamping job at less hassle for your techs.
5) How do I order the Metallics TP144SFC and what is the part number?
Order by Metallics part number TP144SFC. It is sold as a 100 piece pack of 3/8-16 x 2 inch flat head hex pin tamper-resistant machine screws, so one pack covers 100 fastening points.
