Metallics JSHC34134 3/4-10 x 1-3/4 in. Socket Head Hex Cap Screws - Alloy Steel Black - Each

Yes. The JSHC34134 is a 3/4-10 UN thread, 10 threads per inch, 1-3/4 inch long. That is the standard coarse 3/4 inch thread, so it mates with any 3/4-10 tapped hole or nut. Dimensions follow ASME B18.3-2012, the inch socket cap screw standard, so head geometry drops into standard counterbores.

The alloy steel socket head cap screw is rated 170,000 psi minimum tensile and 162,000 psi minimum yield, hardness Rockwell C39. Metallics states it supplies greater tensile strength than equivalent sizes of Grade 5 or Grade 8 hex head cap screws, and because it is internally wrenched it needs less surface area or counterbore clearance than an externally wrenched hex head. If your drawing calls out a Grade 8 hex bolt by spec rather than by strength, confirm the callout allows a socket head.

No. The JSHC34134 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic preference clause, specify a domestically sourced socket head cap screw instead.

It's an internal hex (Allen) drive, not an external wrench head. Socket depth is 0.37 inch, so you need a long enough key to bottom out properly. Head width runs 1.107 to 1.125 inch and head height 0.74 to 0.75 inch, which is what you size the counterbore to.

These ship in a jar with a 25 each order minimum, so the smallest purchase is 25 screws. Jar weight is listed at 2.75 lbs. Other sizes and quantities are available by request.

Metallics lists these for the electrical, plumbing, heating and air conditioning trades. In practice a 3/4-10 x 1-3/4 alloy socket cap screw is a structural attachment fastener, used for bolting equipment feet, strut and bracket connections, and machine mounting where a high-strength screw has to sit in a counterbore or tight clearance that will not take a wrench on a hex head.
