Metallics TP529SBC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP529SBC?
A #12 x 1 inch sheet metal screw with a button head and a hex drive with a center pin, made from 18-8 stainless steel. It is sold 100 pieces to a pack under part number TP529SBC.
2) What driver do I need for the pin-in-hex button head on these Metallics screws?
A pin-in-hex (hex-pin) security bit, not a standard hex key. The center pin in the recess blocks a plain Allen wrench, which is the point of the design, so the TP529SBC needs the matching tamper-resistant hex-pin bit in the right size.
3) Are these tamper-resistant screws suitable for outdoor or damp locations?
They are 18-8 stainless steel, which is the common corrosion-resistant austenitic grade used for exterior and washdown work, so damp and outdoor service is reasonable. For coastal salt exposure, a 316 stainless fastener holds up better than 18-8.
4) Will a #12 x 1 inch sheet metal screw hold in a steel enclosure or strut?
Sheet metal threads are made for thin metal, so a #12 x 1 inch SMS bites well in enclosure walls, covers, panel flanges, and light-gauge framing. The 1 inch length leaves plenty of thread past typical sheet thickness. For thicker structural steel, a machine screw into a tapped hole or a self-drilling fastener rated for that thickness is the better call.
5) Why use tamper-resistant screws on electrical covers and fixtures?
They keep covers, panels, fixture lenses, and device plates in public or shared areas from being opened with common tools. The TP529SBC has a pin-in-hex button head, so anyone without the matching security bit is stopped. It is a frequent spec for schools, transit, multi-family common areas, and exterior fixtures.
6) Does the button head on the TP529SBC sit flush with the surface?
No. A button head is a low-profile rounded head that sits on top of the material, not sunk into it. If you need a flush surface, you want a flat-head screw in a countersunk hole instead. The TP529SBC pairs with an unprepped hole and sits slightly proud.
7) How many screws come in a pack of Metallics TP529SBC?
100 pieces per pack. That is a practical quantity when you are standardizing one security head across a run of covers or fixtures and want spares on the truck.
