  • 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

    • 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)
    • 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
    • 5/16-18 Diameter, 1/2" Length

Metallics JSHC51612 – Frequently Asked Questions

1) Will a 5/16-18 socket head cap screw thread into a standard 5/16-18 tapped hole or nut?
Yes. The JSHC51612 is cut 5/16-18 UN thread, 18 threads per inch, which is the standard coarse 5/16 series, so it mates with any 5/16-18 tapped hole, nut, or insert. Usable thread length is 1/2 in., so your tapped depth plus any clamped material has to stay under that.
2) Is a socket head cap screw stronger than a Grade 5 or Grade 8 hex bolt?
In this size, yes. The Metallics SHC alloy steel socket head cap screw is rated 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, and it does it in a smaller head footprint. Hardness is Rockwell C39. If your drawing calls out Grade 5 or Grade 8 specifically, note this is an alloy socket head screw, not a graded hex head, so the head marking and head geometry will not match.
3) Do these Metallics cap screws qualify as Buy American or ARRA compliant for a federal job?
No. The Metallics SHC socket head cap screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, these will not pass, and you'll need a domestically produced alloy socket head cap screw instead.
4) Does this cap screw meet ASME B18.3?
The JSHC51612 is built to ASME B18.3-2012, the dimensional standard for socket head cap screws. That's the spec to reference if a submittal or inspector asks for dimensional conformance on head diameter, head height, and socket depth.
5) How many 5/16-18 x 1/2 socket head cap screws come in a jar?
These ship in a jar with a 100 piece minimum, so the base order quantity is 100 screws. Catalogued weight for the packed jar is 2.09 lbs.
6) Is the black finish on these alloy socket head cap screws corrosion resistant for outdoor use?
Material is alloy steel with a black finish, which is a plain black oxide type appearance, not a plated or galvanized coating. It gives minimal corrosion protection, so for wet, exterior, or washdown locations use a plated or stainless fastener instead. For dry interior electrical, plumbing, and HVAC work, which is what the SHC series is sold into, the black alloy screw is the normal choice.
7) What tool drives a Metallics JSHC51612 cap screw?
It takes a hex key (Allen wrench) in the socket, not a wrench on the outside of the head. Drive type is hex and the head is a socket head, so plan on a hex key or hex bit socket at the point of install. The internal drive is also what lets the screw sit down in a counterbore where there's no room to swing a wrench.
