  • 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)
    • 1/4-20 Diameter, 5/8" Length
    • Socket head with Hex Drive
    • Alloy Steel Black Material
    • 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.

  • 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 JSHC1458 – Frequently Asked Questions

1) Will a 1/4-20 x 5/8 in. socket head cap screw thread into a standard 1/4-20 tapped hole or nut?
Yes. The JSHC1458 is cut 1/4-20 UN thread, 20 threads per inch, so it mates with any standard 1/4-20 tapped hole, coupling, or nut. Usable thread length is 5/8 inch overall, so your tapped depth plus the material you're clamping has to fall inside that.
2) What counterbore size do I need to sink the head of a 1/4-20 socket head cap screw flush?
Head width on the JSHC1458 runs 0.365 to 0.375 in. and head height is 0.244 to 0.25 in., so a counterbore needs to clear roughly 3/8 inch diameter and be at least 1/4 inch deep to bring the head flush. Head geometry follows ASME B18.3-2012, so it drops into standard socket head cap screw counterbore prep.
3) Is a socket head cap screw stronger than a Grade 5 or Grade 8 hex bolt the same size?
Stronger, yes. The alloy steel JSHC1458 is rated 180,000 psi minimum tensile and 162,000 psi minimum yield, which exceeds equivalent sizes of Grade 5 or Grade 8 hex head cap screws. For reference, Grade 8 is the top common hex bolt grade at 150,000 psi tensile. You also get that strength in a smaller head footprint because the screw is wrenched internally.
4) Do Metallics JSHC1458 screws qualify for a Buy American or ARRA-funded project?
No. These are flagged not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If you're on a federally funded job with domestic sourcing requirements, you'll need a domestically manufactured socket head cap screw instead.
5) Can I use these black alloy steel cap screws outdoors or in a wet location?
Keep them dry. The JSHC1458 is alloy steel with a black finish, which is a plain non-plated appearance finish, not a corrosion barrier like hot-dip galvanizing or zinc. For strut, panel, and equipment work inside a building it's fine. For exterior, damp, or corrosive areas pick a galvanized or stainless fastener instead.
6) How are Metallics JSHC1458 cap screws packaged, and is there a minimum order?
They come in a jar of 100, and 100 is the order minimum. If you need a different count or a different length in the SHC socket head series, other sizes and quantities are available by request.
7) What trades actually use these 1/4-20 socket head cap screws?
They're stocked for electrical, plumbing, and HVAC work: mounting enclosures and panels, fastening equipment to brackets, and anywhere a tapped 1/4-20 hole needs a high-strength screw in a tight counterbore. The internally wrenched head is the reason it shows up in crowded gear where there's no room to swing a wrench around a hex head.
