Metallics TP218SBC – Frequently Asked Questions
1) What driver do I need for the Metallics TP218SBC tamper resistant screw?
The TP218SBC is a button head star drive screw with a center pin, so a standard Torx bit will not seat. You need a pin-in-star (Torx-Pin / tamper resistant star) bit with a hole drilled in the center to clear the pin. A plain star bit will bottom out on the pin and spin.
2) Are these Metallics tamper resistant screws stainless, and can they be used outdoors?
They are 18-8 stainless steel, the common austenitic grade used for general corrosion resistance. 18-8 holds up in ordinary outdoor and damp indoor service, which is why it gets specified for exterior enclosures, panel covers and public-area fixtures. For salt spray or coastal exposure, buyers typically step up to 316 instead.
3) Why use a pin-in-star button head screw instead of a regular Phillips machine screw on electrical enclosures?
Security. The pin in the center of the star recess means a common bit from a tool pouch will not back the screw out, so it is used where the public can reach the fastener: panel covers, junction box lids, fixture housings, transit and institutional installs. The low button head also leaves a rounded, low-profile crown that is harder to grip with pliers than a raised pan head. The tradeoff is you must have the matching pin-star bit on site to service it.
4) How many screws come in a pack of Metallics TP218SBC?
Each pack of the TP218SBC is 100 pieces, all the same 1/4-20 x 1 inch button head pin-star configuration. That quantity suits securing a run of covers, plates or enclosure lids on one job rather than a single repair.
