Metallics JSRMO1 Screw 8-32 x 1-1/2 OV PH MS 18-8 SS (Jar 100)

Solid 18-8 stainless, not plated steel. That's the 300 series austenitic grade, so it holds up in damp and outdoor locations where a zinc-plated screw would rust and seize in the tapped hole.

100 screws per jar. The jar pack is meant for a service van or shop bench rather than a single install, so an electrician or maintenance tech can keep 8-32 x 1-1/2 stainless on hand for cover plates and device mounting.

No. It's a machine screw, so the thread is straight and requires a mating 8-32 tapped hole or a nut. For fastening into wood, use a wood screw, and for hollow drywall use an anchor or toggle. The JSRMO1 is for metal-to-metal and device-to-box work.

Yes, that's the reason to pay for 18-8 rather than plated steel. The stainless resists corrosion in exterior, damp, and washdown locations, which matters for anything you may have to remove again later, like a weatherproof cover or a pool and parking lot device. Keep in mind stainless is softer than hardened steel, so drive it without overtorquing to avoid galling the threads.

Oval head sits partly countersunk and leaves a low rounded crown above the surface, so it works where you want a finished look against a flat plate or strap without the head sitting fully proud. If your part is counterbored for a flat head that must finish dead flush, pick a flat head 8-32 instead. The JSRMO1 is oval head with a Phillips drive.

Metallics part number JSRMO1 covers the 8-32 x 1-1/2 oval head Phillips machine screw in 18-8 stainless, jar of 100. That's the number to quote when standardizing a van stock or an MRO fastener bin.
