Metallics JSHC585 5/8-11 x 5 in. Socket Head Hex Cap Screws - Alloy Steel Black - Each

Yes. The Metallics JSHC585 is a 5/8 inch diameter screw with 11 threads per inch in the UN thread form, which is standard 5/8-11 UNC coarse. It mates with any 5/8-11 nut, coupling, or tapped hole. Overall length under the head is 5 inches.

Stronger than both in the same size. The JSHC585 alloy steel socket head screw carries 170,000 psi minimum tensile and 153,000 psi minimum yield, with hardness at Rockwell C37. Grade 8 hex head cap screws in this diameter run 150,000 psi tensile and Grade 5 runs 120,000 psi, so you get more clamp load from the same 5/8-11 thread while using a smaller head footprint.

No. The JSHC585 is flagged not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. For a Buy American project you need a domestically sourced socket head cap screw instead.

The dimensional standard on the Metallics JSHC585 is ASME B18.3-2012, the spec that governs socket head cap screw head and socket geometry in inch sizes. Head dimensions and socket depth are held to that standard, so it drops into prints and counterbores called out to B18.3.

These ship by the jar with a 25 each minimum, so the smallest order is 25 pieces of the JSHC585. Metallics lists other lengths and diameters in the SHC socket head cap screw series by request if 5 inches is not the length you need.

It is internally wrenched with a hex socket drive, so you drive it with an Allen key or a hex bit socket, not a wrench on the head. The finish is plain black alloy steel, meaning black oxide over bare alloy with no plating, so treat it as an indoor or protected fastener. For wet or exterior anchoring, step to a zinc plated or stainless cap screw.

At 5 inches on a 5/8 inch diameter it is well past 3D, so it falls into the length range subject to tensile, yield, elongation and reduction of area testing. Elongation is 10 percent minimum and reduction of area 33 percent minimum on machined specimens. That matters if you are specifying a fastener for a structural or vibration loaded connection rather than general assembly.

Metallics lists the SHC series for electrical, plumbing, heating and air conditioning work: hanging and bracing strut, bolting up equipment frames, pipe supports and machinery mounting where you need high clamp load from a compact head. The 5 inch length suits stacked assemblies or thick members where a shorter screw would not reach full thread engagement.
