Metallics TP614SFC Screws 14 x 5/8 FH Star Pin TR SMS 18-8 (100 pcs)

It's a #14 by 5/8 inch sheet metal screw with a flat head, driven by a star (Torx style) recess with a center pin for tamper resistance. Material is 18-8 stainless steel, and it's packed 100 pieces to the box. Order as part number TP614SFC.

Yes. The pin in the center of the star recess blocks a standard Torx bit, so you need a pin-in-star (Torx-pin / TP) driver bit in the matching size. A plain Torx, Phillips, or square bit will not seat in the TP614SFC head. Stock the bits with the screws if the crew doesn't already carry them.

18-8 (304-series) stainless is the common choice for exterior and damp-location fastening, including coastal-adjacent exterior panels and enclosures, and it won't rust-stain the way plated steel does. For direct saltwater spray or heavy chemical exposure, 316 stainless is the step up. These are #14 x 5/8 inch screws, so they're for thin-gauge sheet attachment, not structural anchoring.

Pin-in-star heads keep public-access covers, panel fronts, junction box lids, and device plates from being opened with a bit out of anyone's pocket. That's why it's a common spec in schools, transit stops, multi-family common areas, and healthcare corridors. The TP614SFC gives you that in a #14 sheet metal thread so it bites directly into sheet steel enclosures without a nut on the back side.

Flat head means a conical underside that seats flush, but only into a countersunk or dimpled hole. In thin sheet metal that usually means a countersunk-punched hole or a factory dimple. If your covers have plain drilled holes, a flat head will stand proud and may rock, so you want a pan or truss head instead. Thread size here is #14 at 5/8 inch length.

100 pieces per box. For a facility standardizing on tamper resistant covers, that's worth noting at the quote stage: a single box covers roughly 25 four-screw covers, so count your openings before ordering one box.
