Metallics TP503SFC Screws 6 x 1-1/2 FH Hx Pin TR SMS 18- (100 pcs)

Yes. The drive is a hex socket with a pin standing up in the center, so a standard hex key or hex bit will not seat. You need a pin-in-hex (hex pin) driver bit or key in the matching size for a #6 screw. Order the driver along with the screws if you don't already carry one, otherwise the box sits on the truck unused.

The point is to keep the public out of the assembly. Pin-in-hex drive means nobody opens the cover with a screwdriver out of a glovebox, which is why these get specified on electrical enclosures, panel covers, transit and school fixtures, restroom accessories, and anything in a corridor or on an exterior wall. If the fastener is in a back-of-house or locked room, a standard Phillips or hex sheet metal screw does the same mechanical job at less cost per driver.

Sheet metal screw threads run the full length and are made to cut into sheet steel or thin metal, and they will hold in solid wood in a pilot hole. They are not a drywall anchor, and the TP503SFC is not self-drilling, so plan on a pilot hole in anything heavier than light-gauge sheet. For hollow wall you need an anchor rated for the load, not this screw on its own.

100 pieces per pack, one part number, TP503SFC. For an MRO crib standardizing on tamper-resistant covers, a 100 count box plus one or two pin-in-hex drivers covers a lot of openings; there are no size or finish choices to pick on this item, so there is nothing else to specify when you order.
