1/2-13 x 2-1/2 in. Socket Head Hex Cap Screws - Alloy Steel Black - 50qty
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
- 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.
- 1/2-13 Diameter, 2-1/2" Length
- Socket head with Hex Drive
- 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

Metallics JSHC712212 – Frequently Asked Questions
1) What size thread do the Metallics JSHC712212 socket head cap screws have, and how long are they?
They're 1/2-13 x 2-1/2 inches: a 1/2 inch nominal diameter with 13 threads per inch, UN thread form, and a 2-1/2 inch length. That is the standard coarse pitch for 1/2 inch, so it mates with 1/2-13 tapped holes and standard 1/2 inch hex nuts.
2) How big a counterbore do I need for a 1/2 inch socket head cap screw head?
The head measures 0.735 to 0.750 inch across and 0.492 to 0.500 inch high, so a counterbore needs to clear roughly 3/4 inch diameter and about 1/2 inch deep if you want the head flush or below the surface. Because the screw is internally wrenched with a hex key, you don't need the wrench clearance around the head that a hex head cap screw of the same diameter demands.
3) Is a socket head cap screw stronger than a Grade 8 hex bolt the same size?
The alloy steel socket head cap screw is rated at 180,000 psi minimum tensile and 162,000 psi minimum yield, with a hardness of Rockwell C39. That is above the equivalent size in Grade 5 or Grade 8 hex head cap screws, and it gets there in a smaller head footprint since it's driven with a hex key instead of a wrench on the flats.
4) What standard do these Metallics cap screws conform to for submittals?
Dimensionally they're built to ASME B18.3-2012, the standard covering socket cap screws and hex keys. For a spec package that is the dimensional reference to cite, along with the 180,000 psi minimum tensile and 162,000 psi minimum yield values. Note they are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple, so they will not satisfy a domestic-sourcing requirement on a federally funded job.
5) How are the JSHC712212 cap screws packaged, and is there a minimum order?
They come in a jar, with a minimum order of 50 each. So you're buying a 50-piece jar rather than loose single screws. Shipping weight on the jar is 7.48 lbs.
6) What drive do I need to install these, and will a hex key seat deep enough?
They take a hex key in the socket, not a wrench on the head. Socket depth is 0.245 inch, so a standard 1/2 inch socket cap screw hex key bottoms out with full engagement. Use a key or hex bit socket, and remember that in a counterbore you need straight-line access above the head for the key.
7) Can I get this socket head cap screw in a different length or larger quantity?
Other sizes and quantities in the Metallics SHC socket head cap screw line are available by request. The JSHC712212 itself is the single 1/2-13 x 2-1/2 inch alloy steel black configuration.
