5/8-11 x 41/2 in. Socket Head Hex Cap Screws - Alloy Steel Black - 25qty
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
- 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)
- 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.
- 5/8-11 Diameter, 41/2" Length
- Socket head with Hex Drive

Metallics JSHC58412 – Frequently Asked Questions
1) Is the Metallics JSHC58412 socket head cap screw stronger than a Grade 8 hex head bolt of the same size?
The JSHC58412 is an alloy steel socket head cap screw rated at 170,000 psi minimum tensile and 153,000 psi minimum yield, and it delivers greater tensile strength than equivalent sizes of Grade 5 or Grade 8 hex head cap screws. Because it is internally wrenched with a hex drive, it also needs less surface area or counterbore clearance than a hex head of the same diameter. Hardness is Rockwell C37.
2) What thread does the Metallics JSHC58412 take, and will it thread into a standard 5/8 coarse tapped hole?
It is a 5/8 in. diameter screw with 11 threads per inch in the UN thread series, which is standard 5/8-11 UNC coarse thread. It will run into any 5/8-11 tapped hole or coarse nut. If your hole is 5/8-18 fine, this is the wrong screw.
3) Do these Metallics socket head cap screws meet Buy American requirements for a federally funded job?
No. The JSHC58412 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries domestic sourcing requirements, this part will not satisfy them.
4) How long is the JSHC58412 cap screw, and is it fully threaded?
Length is 4-1/2 in. under the head on a 5/8-11 screw. At 4-1/2 in. the screw is well past 3 diameters of length, and cap screws at 3D or greater are subject to tensile, yield, elongation and reduction of area testing, so the published strength values apply to this size. Plan your grip length and thread engagement accordingly rather than assuming full thread.
5) Is the black finish on these alloy socket head cap screws suitable for outdoor or wet locations?
The JSHC58412 is alloy steel with a black finish, which is a plain oxide type appearance rather than a zinc or galvanized coating. It is intended for electrical, plumbing, heating and air conditioning work, which in practice means interior and protected applications. For exposed exterior or damp locations, specify a zinc plated or stainless fastener instead.
6) How are Metallics JSHC58412 cap screws packaged and what is the minimum order?
They ship in a jar, with a minimum order of 25 each. That jar quantity weighs 6.3 lbs. Other sizes and quantities are available by request if 25 is not the count you need.
7) What is the right part number to specify for a 5/8-11 by 4-1/2 inch alloy socket head cap screw from Metallics?
Order it as Metallics JSHC58412, part of the SHC socket head cap screw series. That designation covers the 5/8-11 diameter, 4-1/2 in. length, socket head with hex drive, in alloy steel black.
8) What ductility can I expect from these alloy steel socket cap screws if the joint sees shock loading?
Elongation is 10 percent minimum on machined specimens at least 4 diameters long, and reduction of area is 33 percent minimum. Paired with 170,000 psi minimum tensile and Rockwell C37 hardness, that is a high strength fastener with controlled ductility rather than a brittle one.
