Metallics TP231SBC – Frequently Asked Questions
1) What thread size and length is the Metallics TP231SBC tamper resistant screw?
The TP231SBC is a 10-32 x 1 inch machine screw. That is a 10-32 UNF machine screw thread, so it needs a tapped 10-32 hole or a 10-32 nut, not a self-drilling pilot hole like a sheet metal screw. Supplied 100 pieces to the box.
2) What driver do I need for a button head star pin tamper resistant screw?
A pin-in-star (pin-in-Torx) bit, not a standard Torx. The TP231SBC head has a post in the centre of the six-lobe recess, so a plain Torx driver will not seat on it. You need the pin-in-Torx bit in the matching size, and that is the whole point of the fastener: it keeps a standard T-handle or multibit screwdriver off the hardware.
3) Are these Metallics screws stainless, and will they hold up outdoors?
They are 18-8 stainless steel, the common 300 series austenitic grade used for general corrosion resistance. That makes them suitable for damp and outdoor exposure such as exterior fixtures, enclosures and signage. For constant salt spray or coastal marine exposure, 316 stainless is the step up from 18-8.
4) Why use a button head instead of a flat head on tamper resistant screws?
A button head sits proud on the surface and does not need a countersunk hole, so it works on sheet metal, strut, enclosure covers and panels that are only drilled or tapped. If your part is already countersunk and the fastener must finish flush, a button head is the wrong choice and you want a flat head tamper resistant screw instead. The TP231SBC is the button head version.
5) Where are 10-32 tamper resistant stainless screws typically used in electrical work?
10-32 is the standard thread for electrical enclosure and panel hardware, including grounding lugs and tapped cover holes, which is why this Metallics screw is carried as an electrical fastener. The pin-in-star head adds security where the public can reach the cover, such as exterior junction boxes, transit and parking equipment, restroom and institutional fixtures, and anything a property manager does not want opened with a pocket screwdriver.
6) Can I order a smaller quantity than 100 of the TP231SBC?
The TP231SBC is packaged as a 100 piece box, so that box is the unit. For a single cover or two you will still be buying the hundred, which is usually welcome on a fleet of enclosures where you want every cover on the same security head.
