Metallics JSHC10114 10-24 x 1-1/4 in. Socket Head Hex Cap Screws - Alloy Steel Black - Each

Yes. The Metallics JSHC10114 is a 10-24 screw with 24 threads per inch in the UN (Unified National) thread form, so it mates with any standard 10-24 tapped hole, nut, or strut insert. Shank length is 1-1/4 inches, so figure your material stack plus enough thread engagement to land inside that.

Stronger, yes. The alloy steel JSHC10114 is rated 180,000 psi minimum tensile and 162,000 psi minimum yield, hardness Rockwell C39, which is above what equivalent sizes of Grade 5 or Grade 8 hex head cap screws deliver. It also needs less surface area or counterbore diameter because the drive is internal. Elongation is 10% minimum and reduction of area 33% minimum on machined specimens.

No. The JSHC10114 cap screw is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your project has domestic-sourcing requirements, you need a domestically produced fastener instead.

It's an internally wrenched socket head with a hex drive, so you drive it with an Allen key, not a wrench on the outside of the head. Socket depth is 0.09 inch. Head diameter runs 0.303 to 0.312 inch and head height 0.185 to 0.19 inch, which is what lets it sit in a tight counterbore where a hex head would need clearance all the way around.

Plan on indoor or protected use. The JSHC10114 is alloy steel with a black finish, which is a mill/oxide-type appearance rather than a corrosion coating like zinc or stainless. For wet, exterior, or washdown locations choose a zinc plated or stainless socket head screw in the same 10-24 x 1-1/4 size instead.

It is built to ASME B18.3-2012, the dimensional standard for socket head cap screws and hex keys. That means head diameter, head height, and socket size fall in the standard envelope, so it drops into counterbores machined to B18.3 and takes a standard Allen key.

They ship in a jar, 100 pieces, and 100 is the order minimum. Shipping weight on the jar is 1.32 lbs. Other sizes and quantities are available by request.

Metallics lists the application as the electrical, plumbing, heating and air conditioning industries. In practice that is panel and enclosure hardware, equipment mounting, strut and bracket assemblies, and machine work where the head has to sit in a counterbore and still carry high load.
