  • 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.

  • Features

    • 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.
    • Socket head with Hex Drive
    • 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)

Metallics JSHC381 – Frequently Asked Questions

1) What thread does the Metallics JSHC381 socket head cap screw have, and will it run into a 3/8-16 tapped hole?
It is a 3/8-16 UN thread, 16 threads per inch, with a 1 inch length under the head. That is the standard coarse 3/8 series, so it threads into any 3/8-16 tapped hole or nut. Pick the length against your clamped thickness plus enough engagement in the tapped member.
2) How strong is this socket head cap screw compared to a Grade 5 or Grade 8 hex bolt?
The alloy steel socket head cap screw is rated 180,000 psi minimum tensile and 162,000 psi minimum yield, hardness Rockwell C39. That is above what equivalent sizes of Grade 5 or Grade 8 hex head cap screws provide, and it does it in a smaller head because the screw is internally wrenched. For structural steel connections governed by a bolt spec on the drawing, confirm the spec calls out socket head cap screws rather than a graded hex bolt.
3) What standard are these Metallics socket head cap screws made to?
Dimensions conform to ASME B18.3-2012, the socket cap screw standard, so head, socket, and thread geometry are interchangeable with any other B18.3 socket head cap screw of the same 3/8-16 x 1 in. size. That matters when you're mixing a replacement into an existing run of screws on a panel or machine base.
4) Is the JSHC381 sold individually or by the jar, and what's the minimum order?
These ship in a jar with a 100-count minimum order, so the buying unit is a jar of 100 rather than a single screw. Other sizes and quantities are available by request if you need a different length or diameter in the same alloy steel black socket head.
5) Are these black socket head cap screws okay for outdoor or damp locations?
The material is alloy steel with a black finish, which is a plain, non-plated appearance. Alloy steel socket head cap screws like this are intended for dry indoor mechanical and equipment work, not weather exposure. For exterior or wet locations, choose a zinc plated or stainless fastener instead.
6) What drive do these cap screws take, and is a screwdriver or a wrench needed?
Drive is an internal hex socket, so you drive it with an Allen key or hex bit socket seated in the head, not a screwdriver and not an open-end wrench. Socket depth is 0.182 in. Keep a hex key with clean corners on hand; a worn key is what rounds these out.
7) Do these cap screws qualify for a Buy American or ARRA funded job?
The Metallics JSHC381 is flagged compliant for both Buy American and ARRA requirements. Country of origin is listed as multiple, so if your project needs documentation tied to a single country of manufacture, request it against the specific lot you receive.
