  • Features

    • Socket head with Hex Drive
    • Supplies greater tensile strength than equivalent sizes of Grade-5 or Grade-8 hex head cap screws while requiring less surface area or counterbore since the fastener is intenally wrenched.
    • Alloy Steel Black Material
    • 3/4-10 Diameter, 2-1/2" Length
    • Elongation is 10% minimum (applies to machined specimens of lenglh at least 4D where D equals the nominal diameter of the screw) and Reduction of Area is 33% minimum (applies to machined specimens)

  • Additional Notes

    • Other sizes and quantities available by request | Cap screws of a length 3D or greater, where D equals the nominal diameter of the screw, are subject to tensile strength, yield strength, elongation and reduction of area testing.

Metallics JSHC34212 – Frequently Asked Questions

1) Will a Metallics JSHC34212 socket head cap screw thread into a 3/4-10 tapped hole?
Yes. The JSHC34212 is a 3/4 inch diameter screw with 10 threads per inch in the UN thread series, which is standard 3/4-10 UNC coarse thread. It threads into any 3/4-10 tapped hole or takes a standard 3/4-10 nut. Usable length is 2-1/2 inches.
2) What counterbore diameter and depth do I need for this 3/4 inch socket head cap screw?
Head width runs 1.107 to 1.125 inches and head height is 0.74 to 0.75 inch, so a counterbore has to clear at least 1.125 inches in diameter. Size the depth off 0.75 inch of head if you want it flush or below the surface. The screw is made to ASME B18.3-2012, so those head dimensions follow the standard socket cap screw geometry.
3) Is a socket head cap screw stronger than a Grade 8 hex head bolt of the same size?
The JSHC34212 is alloy steel rated 170,000 psi minimum tensile and 162,000 psi minimum yield, with a hardness of Rockwell C39. That's above the strength of equivalent sizes of Grade 5 or Grade 8 hex head cap screws, and because it's wrenched internally it needs less surface area or counterbore clearance than a hex head.
4) Will these Metallics cap screws meet a Buy American or ARRA requirement on a public job?
No. The JSHC34212 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project specification carries a domestic sourcing clause, this fastener won't satisfy it.
5) What size hex key drives a 3/4-10 socket head cap screw, and how deep is the socket?
It's an internally wrenched socket head taking a hex key, with a socket depth of 0.37 inch. No wrench clearance around the head is needed, which is why these go into counterbores and tight pockets where a hex head cap screw won't fit.
6) Is the black finish on these alloy steel cap screws suitable for outdoor or wet locations?
These are alloy steel with a black finish, which is an oil/black oxide type appearance rather than a plated corrosion coating. It's a dry-location, structural-strength fastener for electrical, plumbing, heating and air conditioning work. For exterior or damp installs, use a zinc plated or stainless cap screw instead.
7) How much does a jar of 25 of the 3/4-10 x 2-1/2 socket head cap screws weigh for shipping?
The 25-piece jar comes in at 4.1 lbs, in a package measuring 4.5 in length by 4.5 in width by 7.25 in height. Useful if you're staging boxed hardware for a multi-site MRO shipment.
