5/16-18 x 2 in. Socket Head Hex Cap Screws - Alloy Steel Black - 100qty
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
- 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.
- 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, 2" Length

Metallics JSHC5162 – Frequently Asked Questions
1) What thread does the Metallics JSHC5162 socket head cap screw have, and will it go into a 5/16-18 tapped hole?
It's a 5/16-18 UN thread, 18 threads per inch, 2 inches long. That mates with any standard 5/16-18 coarse tapped hole or nut. If your hole is 5/16-24 fine thread, this is the wrong screw.
2) How big is the head on a 5/16-18 socket head cap screw, for sizing a counterbore?
Head width runs 0.457 to 0.469 inch and head height 0.306 to 0.312 inch. Size the counterbore off the upper figures, 0.469 diameter plus clearance and at least 0.312 deep if you want the head flush.
3) Is a socket head cap screw stronger than a Grade 5 or Grade 8 hex bolt the same size?
Yes. The alloy steel socket head cap screw is rated 180,000 psi minimum tensile and 162,000 psi minimum yield, hardened to Rockwell C39, which is above what equivalent-size Grade 5 or Grade 8 hex head cap screws deliver, and it does it in less surface area because the screw is wrenched internally. If the drawing calls for a Grade 8 hex bolt and head clearance is tight, the socket head is the substitution to look at.
4) Is the black finish on these alloy steel cap screws suitable for outdoor or wet locations?
These are plain alloy steel with a black finish, not a plated or galvanized corrosion finish. Use them dry and indoors, in equipment, panels, strut brackets and mechanical assemblies. For wet, exterior, or washdown work, specify a zinc plated or stainless socket head cap screw instead.
5) Are these Metallics cap screws Buy American or ARRA compliant for a government or public project?
No. The JSHC5162 is not Buy American compliant and not ARRA compliant, with multiple countries of origin. On a federally funded job with domestic sourcing requirements, you'll need a domestic-origin socket head cap screw instead.
6) Which dimensional standard do these socket head cap screws conform to?
ASME B18.3-2012, the standard for socket head cap screws. That's what lets you cross them against a spec or drawing calling out a B18.3 socket cap screw of the same diameter and length.
7) What trades actually use the 5/16-18 x 2 in. socket head cap screw?
Metallics lists it for the electrical, plumbing, heating and air conditioning trades. Typical use is mounting equipment and brackets, strut and channel assemblies, pump and compressor hardware, and anywhere a high-strength screw has to sit in a counterbore or a pocket too tight for a wrench on a hex head.
8) How much does a jar of 100 of these 5/16-18 x 2 in. cap screws weigh?
4.98 lbs for the jar of 100. Useful if you're building a materials list or checking a parcel weight on a bulk order.
