Metallics TP530SFC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP530SFC?
The TP530SFC is a #12 x 1-1/4 inch sheet metal screw with a flat head and a hex pin tamper-resistant drive, in type 18-8 style stainless designation as noted in the product data. It ships 100 pieces to the box under part number TP530SFC.
2) Do I need a special bit to drive the Metallics TP530SFC tamper-resistant screw?
Yes. The TP530SFC uses a hex head with a center pin, so a standard hex key or socket will not seat. You need a pin-in-hex (hex pin) driver bit sized to the recess. That drive style is what makes it tamper resistant, which is why it gets used on cover plates, enclosures and public-area fixtures where you do not want the screw backed out with common tools.
3) Will a #12 x 1-1/4 inch flat head sheet metal screw sit flush on an electrical cover plate?
A flat head screw is designed to sit flush in a countersunk or chamfered hole, so on a plate with countersunk holes the TP530SFC will finish flush. On a plate with plain punched holes it will stand slightly proud. The 1-1/4 inch length gives you real thread engagement into sheet metal or a strap behind the plate, so it is longer than a typical device-mounting screw.
4) Is the TP530SFC a self-tapping screw for sheet metal, or does it need a tapped hole?
It is a sheet metal screw (SMS), so it forms its own thread in a correctly sized pilot hole in sheet metal. You do not need to tap the hole first, but you do need a pilot: driving a #12 SMS into unpilotted steel will deform the material or snap the drive.
5) How many Metallics TP530SFC screws come in a box?
One hundred pieces per box. For an MRO or facilities crew standardizing tamper-resistant fasteners across panels, enclosures or restroom and corridor fixtures, that is a single part number to stock rather than a mixed drawer.
