Metallics JSHC38134 – Frequently Asked Questions

1) What size and thread does the Metallics JSHC38134 socket head cap screw have?
It's a 3/8-16 x 1-3/4 inch screw: 3/8 inch nominal diameter with 16 threads per inch in a UN (Unified National) thread form, and a 1-3/4 inch length. That's the standard 3/8-16 coarse thread, so it mates with any 3/8-16 tapped hole or nut.
2) Is a socket head cap screw stronger than a Grade 8 hex bolt the same size?
The alloy steel socket head cap screw runs 180,000 psi minimum tensile and 162,000 psi minimum yield, which is above equivalent sizes of Grade 5 or Grade 8 hex head cap screws. It also needs less surface area or counterbore clearance than a hex head because it's wrenched internally through the hex socket. Hardness is Rockwell C39.
3) What size counterbore do I need for a 3/8-16 socket head cap screw?
Size the counterbore off the published head dimensions: head width is 0.55 to 0.562 inch and head height is 0.368 to 0.375 inch. A 3/8-16 socket head cap screw to ASME B18.3-2012 drops into a standard 3/8 socket head counterbore, and the head must sit at or below flush, so the bore depth needs to clear 0.375 inch.
4) Do these Metallics cap screws qualify for a Buy American or ARRA job?
No. The JSHC38134 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded or domestic-content job you'll need a domestically sourced socket head cap screw instead.
5) Does the JSHC38134 cap screw take a hex key or a wrench?
Hex key. The head is a socket type with a hex drive, so it's driven with an Allen key or hex bit from the top, not with an open-end or socket wrench on the outside of the head. Socket depth is 0.182 inch.
6) How are these Metallics socket head cap screws packaged and what is the minimum order?
They ship in a jar of 100, and 100 is the order minimum. If you need a different size or a different count, Metallics lists other sizes and quantities as available by request.
7) Is the black finish on these alloy steel cap screws corrosion protected for outdoor or wet use?
The material is alloy steel with a black finish, which is a plain thermal/oxide type black rather than a plated coating. Treat it as an indoor or protected application fastener. For wet, exterior, or washdown locations, specify a zinc plated or stainless socket head cap screw in the same 3/8-16 x 1-3/4 size instead.
8) Can I use these for strut, equipment mounting, and pipe hanger work?
Yes, these are specified for the electrical, plumbing, heating and air conditioning trades, which is typical socket head cap screw duty: equipment and motor mounting, hanger and bracket assembly, and anywhere a high-strength 3/8-16 fastener has to pull down in a counterbored or tight-clearance location.
