Metallics JSHC1058 10-24 x 5/8 in. Socket Head Hex Cap Screws - Alloy Steel Black - Each

Yes. The Metallics JSHC1058 is a 10-24 UN thread cap screw with 24 threads per inch, so it mates with any standard 10-24 tapped hole, nut, or strut insert. Usable thread length is 5/8 inch overall screw length, so allow for the head and the material thickness you are clamping when you check engagement depth.

No. The JSHC1058 socket head cap screw is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, you need a domestically produced fastener instead.

Socket head is the one to use in tight quarters. At 180,000 psi minimum tensile and 162,000 psi minimum yield, the alloy steel socket head cap screw carries more load than the same size Grade 5 or Grade 8 hex head, and the internal hex drive means you can seat it in a counterbore or against an adjacent surface where a wrench or socket would never fit. Go hex head instead when you want to drive it with common open-end wrenches in the field rather than hex keys.

It is built to ASME B18.3-2012, the dimensional standard for socket head cap screws, so head diameter, head height, socket size, and thread will interchange with any other B18.3 socket head cap screw in 10-24 x 5/8 in. That matters if you are standardizing fasteners across a facility and want to mix stock without re-checking counterbores.

They ship in a jar of 100 pieces, and one jar is the order minimum. Shipping weight on the jar is 0.7 lbs. Other sizes and quantities can be arranged by request.

Rockwell C39 hardness on alloy steel is what keeps the hex socket from rounding out at the torque this screw is rated for. Use a proper hex key fully seated in the socket; the socket depth is 0.09 in., so a worn or short key bottoming out in the recess is the usual cause of a stripped drive.

Only screws 3D or longer, where D is the nominal diameter, get tensile strength, yield strength, elongation, and reduction of area testing. For the 10-24 size, 5/8 in. clears that threshold. Published minimums are 180,000 psi tensile and 162,000 psi yield, with 10 percent minimum elongation and 33 percent minimum reduction of area on machined specimens.
