Metallics TP524SBC – Frequently Asked Questions
1) What size and type of screw is the Metallics TP524SBC?
It's a #8 x 2 inch sheet metal screw with a button head and a pin-in-hex (tamper resistant) drive, made from 18-8 stainless steel. Sold 100 pieces to a box. The pin in the center of the hex recess means a standard hex key won't turn it, you need a pin-in-hex driver bit sized for the recess.
2) Do I need a special driver bit for the Metallics TP524SBC, and is one included?
You need a pin-in-hex (also called pin-hex or hex-pin) bit, which has a hole bored down the center to clear the pin in the screw recess. The 100-piece box is screws only, so order the matching driver bit separately if your crew doesn't already carry one. A standard hex key or Allen bit will not seat.
3) Why use a tamper resistant screw like the TP524SBC instead of a standard Phillips sheet metal screw?
The pin-in-hex recess is there to stop casual removal. On electrical work that means covers, enclosures, device plates, and exterior fixtures in public or tenant-accessible areas, where you don't want anyone opening the box with a screwdriver out of a pocket. A regular Phillips or slotted sheet metal screw of the same #8 x 2 size holds the same, it just doesn't deter anybody.
4) Are these #8 x 2 stainless screws OK for outdoor or damp locations?
18-8 stainless is an austenitic chromium-nickel grade and is the usual choice for general outdoor and damp-location fastening, so corrosion resistance is far better than a plain or zinc-plated steel screw. It is not a marine grade like 316, so in direct salt spray expect some surface staining over time.
5) Will a 2 inch long sheet metal screw be too long for mounting a device plate or thin cover?
Probably, yes. At 2 inches of length, the TP524SBC is meant for fastening through a cover or bracket and well into wood, a stud, or a thick substrate. For a plate screwed to a box ear or sheet metal flange, a 2 inch screw will bottom out or protrude behind the surface. Pick a shorter length in the same pin-in-hex button head family for thin-to-thin fastening.
6) What does the button head on the TP524SBC mean for the finished surface?
A button head sits on top of the material with a low, domed profile rather than pulling flush into a countersink. No countersinking or beveled hole is needed, and it leaves a rounded head proud of the surface, which also gives less purchase for prying than a flat socket head.
7) Is the Metallics TP524SBC sold individually or by the box?
By the box, 100 screws per box, under part number TP524SBC. There is a single configuration, so there is no finish or drive option to specify when ordering.
