Metallics TP340SFC Screws 10-32 x 2 FH Span TR MS USA 18 (100 pcs)

The TP340SFC is a 10-32 x 2 inch machine screw. The 10-32 thread means it mates with a tapped 10-32 hole or a 10-32 nut, and the 2 inch length is the full shank under the flat head, since flat head screws are measured overall when countersunk.

It takes a spanner bit, also called a snake-eye bit: two round pins that seat in the two holes in the head. A Phillips, square or Torx bit will not engage it. If you are installing these for tamper resistance, order the matching spanner driver bit at the same time, because no standard screwdriver will work.

Yes. It is a flat head (FH) screw, so the conical head seats into a countersink or a factory-countersunk plate and finishes level with the surface. For a flush result the hole needs an 82 degree countersink, which is the standard angle for inch-series flat head machine screws. If you need the head to stand proud or you are fastening into a flat, un-countersunk surface, a pan or truss head is the better choice.

Machine screw. The TP340SFC has a straight, fully threaded 10-32 machine thread, so it requires an existing tapped hole or a nut. It will not cut its own thread in sheet metal the way a self-drilling or sheet metal screw does. If the hole is unthreaded, you need to tap it to 10-32 first or back it with a 10-32 nut.

100 pieces per box. For MRO stockrooms and security integrators standardizing on spanner-drive fasteners, that quantity covers a run of cover plates or enclosure lids without reordering mid-job.

Order Metallics TP340SFC. That single manufacturer part number covers the 10-32 x 2 inch flat head spanner tamper-resistant machine screw in the 100 piece box, so there are no finish or pack options to specify.
