Metallics JSHHMS13 Screw 6-32 x 1-1/2 Hx Hd MS 18-8 SS (Jar 100)

It's a 6-32 x 1-1/2 inch machine screw, so a #6 diameter with 32 threads per inch and a 1-1/2 inch length. The 6-32 thread is the standard machine screw thread used on device and switch boxes, so it mates with tapped holes and 6-32 nuts.

18-8 stainless, not plated carbon steel. That's the 300 series austenitic grade, which is why it gets specified for damp locations, exterior enclosures, and corrosive environments where a zinc-plated screw would rust out.

Hex head. You drive it with a wrench or a hex socket driver rather than a screwdriver bit, which is what you want when you're setting a lot of them or need more torque than a slotted head will take.

100 screws, supplied in a jar. The jar pack is the shop and service-truck quantity, so it suits a van stock or an MRO crib rather than a single-fixture repair.

Yes, and that's the usual reason to buy the stainless version. 18-8 resists corrosion in damp, exterior, and coastal installs, so it holds up on outdoor enclosures, pool and marina equipment, and wash-down areas where plated steel screws seize or rust. Just avoid pairing stainless hardware against dissimilar metals in standing moisture if galvanic corrosion is a concern on the job.

No. It's a machine screw only, 100 per jar. If you're through-bolting rather than threading into a tapped hole, order 6-32 nuts and washers separately, and match them in 18-8 stainless so you don't put a plated nut on a stainless screw.

One part, one model: JSHHMS13, the 6-32 x 1-1/2 hex head 18-8 stainless machine screw in a 100-count jar. There's no size, finish, or length choice to specify on the order.
