  • Features

    • 1/2-13 Diameter, 1" Length
    • 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
    • Alloy Steel Black Material

  • 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.

Metallics JSHC7121 – Frequently Asked Questions

1) Will a 1/2-13 socket head cap screw thread into a standard 1/2 inch UNC tapped hole?
Yes. The Metallics JSHC7121 is a 1/2 inch diameter screw with 13 threads per inch in the UN thread form, which is standard 1/2-13 UNC coarse thread. It drops into any 1/2-13 tapped hole or mates with a standard 1/2-13 nut. Usable length under the head is 1 inch.
2) Is a socket head cap screw stronger than a Grade 8 hex bolt in the same size?
This 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. It also needs less surface area or counterbore clearance because it is wrenched internally rather than across flats. Hardness is Rockwell C39.
3) How many screws do I get, and can I buy just one?
These ship in a jar of 100 pieces, and 100 is the order minimum. If you need a different count or a different length, other sizes and quantities are available by request.
4) Will these pass a Buy American or ARRA requirement on a public job?
No. The JSHC7121 cap screws are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On federally funded work with domestic-content requirements you will need a domestically sourced fastener instead.
5) Does the black finish on these cap screws hold up outdoors?
The material is alloy steel with a black finish, which is an oxide-type appearance coating rather than a corrosion barrier. For wet, exterior, or washdown locations use a plated or stainless fastener instead. Indoors, in panels, enclosures, machinery, and mechanical mounting, the black alloy screw is the normal choice.
6) Do these socket head cap screws meet a recognized dimensional standard for inspection?
Yes, they are made to ASME B18.3-2012, the standard that governs socket head cap screw head and thread dimensions. That is the figure to cite on a submittal when a spec calls for B18.3 socket screws.
7) What trades actually use these black alloy socket head cap screws?
They are stocked for electrical, plumbing, heating and air conditioning work, so typical uses are mounting equipment, brackets, panels, and machinery where a flush or counterbored head is wanted. Electricians and mechanical contractors use the 1/2-13 size for strut, bracket, and equipment attachment into tapped holes.
