Metallics JSHC101SS 10-24 x 1 in. Socket Head Hex Cap Screws - 18-8 Stainless - Each

Yes. The Metallics JSHC101SS is a 10-24 UNC screw, 24 threads per inch in the coarse unified series, so it mates with any standard 10-24 tapped hole, nut, or insert. Thread length is governed by the 1 inch overall screw length.

The material is 18-8 stainless, the common austenitic grade used where plain or zinc-plated steel would rust, so it suits damp interior, washdown, and general exterior enclosure and strut work. It is not a hardened alloy screw, so treat it as a corrosion-resistant fastener rather than a high-strength one.

Rated at 80,000 psi minimum tensile and 30,000 psi minimum yield, with a hardness of Rockwell B80. That is the stainless property class, well below a Grade 8 or alloy black-oxide socket screw. If your connection is carrying a calculated structural load, step up to an alloy steel socket head cap screw; if it is panel, strut, or enclosure work in a corrosive spot, these numbers are the right trade-off.

It is a socket head driven with a hex key, not a wrench flat. Head diameter runs 0.303 to 0.312 in. and head height 0.185 to 0.190 in., and the screw is made to ASME B18.3-2012, so it drops into a counterbore machined to that standard for a #10 socket head cap screw. Socket depth is 0.09 in., so seat the key fully before applying torque.

It ships as a jar with a minimum order of 100 count, so one order gets you 100 of the 10-24 x 1 in. screws rather than a loose piece. Packed weight is 0.98 lbs.

The JSHC101SS is flagged ARRA compliant and Buy American compliant in Metallics' product data, which is the designation procurement officers on publicly funded work look for. Country of origin is listed as multiple, so if your specification requires a single documented country of melt and manufacture, ask for the mill paperwork on the lot you receive.

Use the socket head where clearance is tight or the head has to sit flush in a counterbore, because it is driven from above with a hex key instead of needing swing room for a wrench. A hex head bolt is the better pick when you want to run it with a socket or impact and you have open access. At 10-24 x 1 in. with a 0.303 to 0.312 in. head, this one is sized for small device, bracket, and enclosure mounting rather than heavy framing.

Overall screw length is 1 inch measured below the head, so your combined material thickness plus any nut or insert engagement has to fall inside that. For a #10 screw, plan on roughly a diameter and a half of thread engagement into tapped steel or aluminum and subtract that from the 1 inch to get your usable clamp thickness. Metallics lists other lengths in the SHC series if 1 inch comes up short.

18-8 stainless socket head cap screws keep their mechanical and performance properties above ambient temperature, which is why they get specified in enclosures and equipment that run warm. Elongation is 10 percent minimum and reduction of area 33 percent minimum on machined specimens, so the material stays ductile rather than brittle.
