3/8-16 x 1-1/4 in. Socket Head Hex Cap Screws - Alloy Steel Black - 100qty
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
- 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
- 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)
- 3/8-16 Diameter, 1-1/4" Length

Metallics JSHC38114 – Frequently Asked Questions
1) What thread and size are the Metallics JSHC38114 socket head cap screws?
They are 3/8-16 x 1-1/4 inch screws, so a 3/8 inch nominal diameter with 16 threads per inch in the UN thread series. That is the standard coarse 3/8 thread, so it mates with any 3/8-16 tapped hole or nut.
2) How strong is a 3/8-16 alloy steel socket head cap screw compared with a Grade 8 hex bolt?
The Metallics SHC alloy steel screw is rated at 180,000 psi minimum tensile and 162,000 psi minimum yield, with a hardness of Rockwell C39. That puts it above a comparable Grade 8 hex head cap screw, which is a 150,000 psi minimum tensile fastener, and it does it in a smaller head footprint because it is internally wrenched.
3) How much counterbore clearance do I need for these socket head cap screws?
Size the counterbore off the head: the head measures 0.55 to 0.562 inch across and 0.368 to 0.375 inch high. Bore the pocket at least that deep if you want the head flush or below the surface, and leave clearance around the 0.562 inch maximum head diameter. The screws are made to ASME B18.3-2012, so standard socket head counterbore charts apply.
4) Do these Metallics cap screws meet Buy American or ARRA requirements for a public project?
No. The JSHC38114 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your job carries a domestic sourcing clause, this is not the fastener to submit.
5) What size hex key drives a 3/8-16 socket head cap screw?
It takes a 5/16 inch hex key. The drive is an internal hex socket, and the socket depth is 0.182 inch, so a standard L-key or hex bit engages fully without bottoming out.
6) How are the Metallics JSHC38114 cap screws packaged, and is there a minimum order?
They ship in a jar of 100, and 100 is the order minimum, so you are buying by the jar rather than by the piece. Metallics lists other sizes and quantities in the SHC series on request.
