Metallics TP227SFC – Frequently Asked Questions
1) What driver do I need for a star pin tamper-resistant screw like the TP227SFC?
A pin-in-star (pin-in-Torx) bit. The screw has a six-lobe star recess with a solid pin in the center, so a standard Torx bit will not seat, it bottoms out on the pin. You need a tamper-resistant star bit of the matching size with a hole bored down the middle. Keep a set on the truck if you're installing these on panels or covers you'll need to service later.
2) Are these 18-8 stainless screws OK for outdoor or damp locations?
18-8 stainless (the common 300-series austenitic grade) handles exterior and damp-location use far better than plated steel, which is why it's specified for outdoor enclosures, pool and locker room fixtures, and coastal work. It is not the best choice in direct salt spray, where 316 stainless is the usual step up. The TP227SFC is 18-8 stainless throughout, so there's no plating to chip and start rusting.
3) Why use a flat head screw instead of a pan or truss head on a cover plate?
Flat head means the screw seats flush in a countersunk or chamfered hole, leaving nothing standing above the surface to catch a hand, a cart, or a pry tool. That matters on wall plates, trim covers, and tamper-resistant panels in public areas. The trade-off: the hole has to be countersunk to accept the 82-degree head. If your existing holes are flat-drilled with no chamfer, a pan or truss head sits better.
4) What is the Metallics part number for the 10-24 x 1/2 pin-in-star stainless flat head screw?
Order it as Metallics TP227SFC. One part number covers the 100-piece box of 10-24 x 1/2 inch flat head pin-in-star tamper-resistant machine screws in 18-8 stainless, so if you're standardizing fasteners across a facility that's the single number to put on the requisition.
5) Do these screws come with nuts or anchors?
No. The TP227SFC box is 100 screws only, with no nuts, washers, or anchors. Because it's a machine screw thread (10-24), the mating hole has to already be tapped, or you need to add a 10-24 nut or threaded insert separately.
6) Will a tamper-resistant star pin screw stop someone from opening a panel?
It stops casual tampering, not a determined attempt. Pin-in-star screws defeat ordinary screwdrivers and standard Torx bits, which is enough for public restrooms, transit shelters, school corridors, and electrical covers where you want to deter opportunistic access. Anyone with the right tamper bit can remove them, so treat the TP227SFC as deterrence rather than security hardware.
