Metallics TPPB102434 Screws 10-24 x 3/4 One-Way Partition (100 pcs)

One-way means the head is driven in but not backed out. The slot is shaped so a driver bites going clockwise and cams out counterclockwise, so once the 10-24 x 3/4 screw is seated it can't be unscrewed with a normal screwdriver. That is the point of using it on toilet partitions, panels and public-area fixtures where you don't want the hardware removed. Plan on cutting or drilling it out if it ever has to come off.

Each box holds 100 pieces of the 10-24 x 3/4 one-way partition screw, ordered under part number TPPB102434. That quantity suits a maintenance shop restocking for multiple restroom partition repairs rather than a single fix.

The 3/4 inch length is sized for fastening through a bracket or shoe into a tapped hole or nut, not for spanning a full panel thickness. Measure your stackup: bracket thickness plus the depth of thread engagement you need has to come in under 3/4 inch, otherwise the screw bottoms out before it clamps. If your partition hardware calls for a longer 10-24 fastener, this one will not reach.

They are 10-24 machine screws, the same thread used on a lot of electrical device and panel hardware, and Metallics catalogues them in its electrical fastener line. The thing to weigh is that they're one-way: once installed you cannot back them out, which is wrong for anything you expect to service. Use conventional 10-24 screws where access matters and save these for fixtures you want locked down.

A standard flat-blade screwdriver or a slotted bit in a drill works for driving. The slot is a tamper pattern, so only the driving direction engages; there is no special tool required to install, and no common tool that removes it. For removal you need a one-way screw extractor or you drill the head off.
