Metallics TP116SFC – Frequently Asked Questions
1) What driver do I need for the Metallics TP116SFC hex pin screw?
It takes a pin-in-hex (hex pin) security bit, not a standard hex key. The recess has a post in the center, so a plain Allen wrench will not seat. That is the point of the drive: it is a tamper-resistant fastener meant to stay put unless someone has the matching security bit on hand.
2) Will a flat head 1/4-20 screw sit flush in my panel?
Yes, provided the hole is countersunk. The TP116SFC has a flat head, which is designed to seat into an 82 degree countersink and finish flush with the surface. On a plain drilled hole with no countersink the head will stand proud, so prep the hole or choose a different head style.
3) Is the TP116SFC a machine screw or a self-tapping screw?
It is a machine screw. The threads are straight and uniform, so it needs a pre-threaded hole or a nut; it will not cut its own thread into sheet metal or plastic. If you are fastening into unthreaded material, you need a tapped hole, a nut, or a thread-cutting type screw instead.
4) How many screws come in a box of Metallics TP116SFC?
Each box holds 100 pieces. For jobs where a few fasteners secure each enclosure or cover plate, that quantity covers a run of openings without reordering, which is typically how security screws are bought for MRO and electrical work.
5) Where are tamper-resistant hex pin screws like the Metallics TP116SFC used in electrical work?
They go where a cover needs to stay closed against casual access: junction box and pull box covers, device and receptacle plates in public corridors, lighting trims, panel escutcheons, and enclosures in schools, transit areas, and multi-family common spaces. The hex pin recess blocks standard hex and screwdriver bits, so maintenance staff with the security bit can open it and nobody else can.
6) What is the Metallics part number for a 1/4-20 x 1/2 inch flat head pin-in-hex security screw?
Metallics catalogs it as TP116SFC. Order by that number to get the 1/4-20 by 1/2 inch flat head hex pin tamper-resistant machine screw in the 100 piece box.
