Metallics TP143SFC – Frequently Asked Questions
1) What thread size and length are the Metallics TP143SFC tamper-resistant screws?
The TP143SFC is a 3/8-16 x 1-1/2 inch machine screw. That is a 3/8 inch diameter with 16 threads per inch, so it mates with a 3/8-16 tapped hole or nut, and the 1-1/2 inch length is measured on a flat head screw from the top of the head down, since the head sits flush in a countersunk hole.
2) What driver do I need for the TP143SFC hex pin screw?
A hex pin (pin-in-hex) bit, not a standard hex key. The drive recess has a pin in the center, so an ordinary Allen wrench will not seat. That is the whole point of the TP143SFC: it is a tamper-resistant fastener, and crews need the matching pin-in-hex driver on hand before they start the install.
3) Is the Metallics TP143SFC sold individually or by the box?
It ships 100 pieces to the pack, so it is ordered as a box rather than a single screw. For MRO stock on fixtures, panels, or enclosures where you want a security drive standard across a site, one pack covers a lot of openings.
4) Will a flat head tamper-resistant screw sit flush, or does it stand proud of the surface?
Flush, provided the hole is countersunk. The TP143SFC is a flat head screw, which is the conical head style made to drop into an 82 degree countersink and finish level with the material face. If your part has a straight-drilled hole with no countersink, the head will stand above the surface and you want a pan or button head instead.
5) Can I run the TP143SFC into wood or drywall?
No. It is a machine screw with a 3/8-16 thread, which is a straight machine thread meant for a tapped hole, a nut, or a threaded insert. It has no sharp point and no spaced thread to cut into wood, so for framing or board you need a wood or self-drilling screw instead.
6) What is the Metallics part number to order for the 3/8-16 x 1-1/2 pin hex tamper-resistant flat head screw?
Order Metallics TP143SFC. That one part number covers the 3/8-16 x 1-1/2 inch flat head, pin-in-hex tamper-resistant machine screw in a 100 piece pack, so there are no size or finish suffixes to add behind it.
