Metallics TP140SFC – Frequently Asked Questions
1) What size and thread are the Metallics TP140SFC screws, and how many come in a box?
The TP140SFC is a 3/8-16 x 3/4 inch machine screw, sold 100 pieces to the box. The 3/8-16 callout is a coarse (UNC) thread, so it threads into a 3/8-16 tapped hole or nut, and the 3/4 inch is the length under the head.
2) Do I need a special bit to install the Metallics TP140SFC tamper-resistant screw?
Yes. It uses a pin-hex (hex socket with a center pin) tamper-resistant drive, so a standard hex key will not seat. You need a pin-in-hex driver or bit sized to the recess. That drive style is the point of the screw: once it is in, nobody opens the enclosure or cover with a common tool from a truck box.
3) Is the TP140SFC a flat head screw that sits flush with the surface?
It is a flat head (FH) machine screw, so it is made to sit flush in a countersunk hole. If the plate or cover you are fastening has a straight, uncountersunk hole, the head will stand proud and you want a pan or button head instead.
4) Can I use a 3/8-16 machine screw in a self-tapping application like sheet metal?
No. The TP140SFC is a machine screw, which means it needs a mating 3/8-16 tapped hole or nut; it will not cut its own thread in sheet metal or form a thread in an untapped hole. For that you want a self-drilling or self-tapping tamper-resistant screw, not this one.
5) How do I order more of the Metallics TP140SFC tamper-resistant screw to match what is already installed?
Order by manufacturer part number TP140SFC. That number pins the whole spec, 3/8-16 thread, 3/4 inch length, flat head, pin-hex tamper-resistant drive, in a 100 piece box, so the replacements match the heads and the driver already on the cart.
