1/4-20 x 1-3/4 in. Socket Head Hex Cap Screws - Alloy Steel Black - 100qty
Features
- 1/4-20 Diameter, 1-3/4" Length
- 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)
- Alloy Steel Black Material
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 JSHC14134 – Frequently Asked Questions
1) Is a 1/4-20 socket head cap screw stronger than a Grade 8 hex head bolt of the same size?
Yes. The alloy steel socket head cap screw runs 180,000 psi minimum tensile and 162,000 psi minimum yield, above what equivalent-size Grade 5 or Grade 8 hex head cap screws deliver. Hardness is Rockwell C39. Because it's wrenched from inside the head, it also needs less surface area or counterbore clearance than an externally wrenched bolt.
2) Will a 1/4-20 socket head cap screw thread into a standard 1/4-20 tapped hole or nut?
Yes. The JSHC14134 is a UN thread form at 20 threads per inch on a 1/4 in. nominal diameter, which is the standard 1/4-20 UNC series. It mates with any 1/4-20 tapped hole, nut, or insert. Thread length and head geometry follow ASME B18.3-2012, so it drops into standard 1/4 in. socket head counterbores.
3) Do these screws qualify for a Buy American or ARRA funded project?
No. The Metallics JSHC14134 socket head cap screw is not Buy American compliant and is not ARRA compliant. Country of origin is listed as multiple. On a federally funded job with domestic sourcing requirements, you'll need a domestically produced fastener.
4) What size hex key do I need for the Metallics JSHC14134 socket head cap screw?
It's an internally wrenched socket head with a hex drive, so you drive it with a hex key, not a wrench on the outside of the head. The head measures 0.365 to 0.375 in. across and 0.244 to 0.25 in. tall, and the socket depth is 0.12 in. A 3/16 in. hex key is the standard drive for a 1/4-20 socket head cap screw built to ASME B18.3.
5) How many Metallics JSHC14134 screws come in a jar, and is there a minimum order?
The screws ship in a jar of 100, and 100 is the order minimum. If you need a different count or another length in the SHC series, other sizes and quantities are available by request.
6) What is this socket head cap screw used for on a commercial job?
The SHC series is specified for electrical, plumbing, heating and air conditioning work: bolting strut and channel assemblies, equipment mounting, panel and enclosure hardware, anywhere a high strength 1/4-20 fastener has to sit in a counterbore or a tight pocket where you can't get a socket on an external head. The internally wrenched head is what makes the tight-clearance installs possible.
