  • 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.
    • 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)
    • 5/8-11 Diameter, 1" Length
    • Alloy Steel Black Material

Metallics JSHC581 – Frequently Asked Questions

1) Will a Metallics JSHC581 socket head cap screw thread into a 5/8-11 tapped hole?
Yes. The JSHC581 is a 5/8-11 UN thread, 11 threads per inch, so it mates with any standard 5/8-11 UNC tapped hole or nut. Usable length is 1 inch, which is short for a 5/8 diameter screw, so it suits thick-walled bosses and tapped plates rather than deep clamp-ups.
2) What size counterbore and clearance do I need for a 5/8-11 socket head cap screw?
Plan the counterbore around a head width of 0.921 to 0.938 in. and a head height of 0.616 to 0.625 in. Because the screw is wrenched internally through the hex socket rather than across flats, it needs less surface area around the head than a hex head cap screw of the same diameter, which is why it works in tight bosses and recessed pockets.
3) Is an alloy socket head cap screw stronger than a Grade 5 or Grade 8 hex bolt?
The JSHC581 alloy steel screw is rated 170,000 psi minimum tensile and 153,000 psi minimum yield, with a hardness of Rockwell C37. The description states it supplies greater tensile strength than equivalent sizes of Grade 5 or Grade 8 hex head cap screws. If your drawing calls out a Grade 8 hex bolt and allows a socket head, this exceeds that tensile figure.
4) Is the Metallics JSHC581 cap screw Buy American or ARRA compliant for a government job?
No. The JSHC581 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic-content requirement, this screw will not satisfy it.
5) What driver do I need for the JSHC581 cap screw?
It takes a hex key (Allen) drive in a socket head, not an external wrench. Socket depth is 0.307 in., so use a full-length key or bit that bottoms properly to avoid rounding the socket at these torque levels.
6) How do these ship, and is there a minimum order quantity?
They come in a jar, with an order minimum of 50 each. It is a bulk MRO pack, not a single fastener, so count on 50 pieces per order.
7) Are black alloy socket head cap screws OK for outdoor or damp locations?
The finish here is plain black alloy steel, not a plated or galvanized coating, so treat it as an indoor or protected-location fastener. For exposed exterior strut, rooftop equipment or wet areas, specify a zinc-plated or stainless cap screw of the same 5/8-11 size instead.
8) What trades use these socket head cap screws?
Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. Typical use is equipment mounting, machine and pump bases, strut and bracket connections where a high-strength internally wrenched screw fits in a pocket an external wrench could not reach.
