  • 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.
    • 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)
    • Alloy Steel Black Material
    • 5/16-18 Diameter, 3" Length

Metallics JSHC5163 – Frequently Asked Questions

1) Is a socket head cap screw stronger than a Grade 8 hex bolt in the same size?
The JSHC5163 alloy steel socket head cap screw is rated 180,000 psi minimum tensile and 162,000 psi minimum yield, which is above what an equivalent-size Grade 5 or Grade 8 hex head cap screw delivers. Hardness is Rockwell C39. It also takes less surface area or counterbore than a hex head because the drive is internal.
2) Do these cap screws meet Buy American or ARRA requirements for a public project?
No. The JSHC5163 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your contract carries domestic sourcing language, these will not satisfy it.
3) What thread does the Metallics JSHC5163 cap screw use, and will it take a standard 5/16-18 nut?
It is a 5/16-18 UN thread at 18 threads per inch, which is standard 5/16 coarse. Any standard 5/16-18 nut or tapped 5/16-18 hole will accept it. Overall length is 3 in.
4) What spec do these socket head cap screws conform to?
Dimensionally they are built to ASME B18.3-2012, the standard for socket cap screws. Because this one is 3 in. long, well past 3 times the 5/16 nominal diameter, it falls under the tensile, yield, elongation and reduction of area testing requirements: elongation 10 percent minimum and reduction of area 33 percent minimum on machined specimens.
5) Can I use alloy steel black socket head cap screws outdoors?
Not without protection. The material is alloy steel with a plain black finish, which is an oil or oxide type finish, not a corrosion barrier like zinc or stainless. Keep these to dry interior work, enclosures, machinery and panel assembly, or coat them. For wet or exposed locations, pick a plated or stainless cap screw instead.
6) How are these 5/16-18 x 3 in. cap screws packaged, and is there a minimum order?
They come in a jar, and the order minimum is 100 count. So a single purchase is a 100-piece jar rather than loose pieces, which is worth knowing if you only need a handful for one panel.
7) What tool drives a Metallics socket head hex cap screw?
A hex key, not a wrench or screwdriver. The head is a socket type with a hex drive, and the socket depth is 0.151 in. Bring an allen key set or a hex bit socket for a driver; there is no external flat to grip.
