5/16-18 x 1 in. Socket Head Hex Cap Screws - Alloy Steel Black - 100qty
Features
- 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.
- 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)
- 5/16-18 Diameter, 1" Length
- Socket head with Hex Drive
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 JSHC5161 – Frequently Asked Questions
1) Will a 5/16-18 socket head cap screw thread into a standard 5/16 coarse tapped hole or strut nut?
Yes. The JSHC5161 is a 5/16-18 UN thread, 18 threads per inch, which is the standard coarse series for 5/16 inch diameter. It mates with any 5/16-18 tapped hole, nut, or channel/strut nut of the same thread. Thread length is governed by the 1 inch overall screw length, so for a blind hole make sure you have at least 1 inch of depth available under the head.
2) How big is the head on this socket head cap screw, and what counterbore does it need?
Head width is 0.457 to 0.469 inch and head height is 0.306 to 0.312 inch, built to ASME B18.3-2012. Size your counterbore off the 0.469 inch maximum head diameter plus clearance, and allow at least 0.312 inch of depth if you want the head flush or below the surface. Socket heads like this need less surface area and a smaller counterbore than a Grade 5 or Grade 8 hex head of the same diameter.
3) Do these cap screws qualify for a Buy American or ARRA funded project?
No. The JSHC5161 socket head cap screws are not Buy American compliant and are not ARRA compliant, with multiple countries of origin. On a federally funded job with domestic sourcing requirements, you'll need a domestically manufactured fastener instead.
4) How are Metallics JSHC5161 cap screws packaged, and what is the minimum order?
They ship in a jar of 100, which is also the order minimum, at 2.83 lbs per jar. If your job needs a different length or diameter in the same socket head alloy series, other sizes and quantities are available by request.
