Metallics JSHC81 8-32 x 1 in. Socket Head Hex Cap Screws - Alloy Steel Black - Each

Yes. The JSHC81 is an 8-32 machine screw thread, 32 threads per inch, cut to the UN thread form, so it mates with any standard 8-32 tapped hole or 8-32 nut. Thread length runs on a 1 inch screw.

The head measures 0.262 to 0.270 inch across and 0.159 to 0.164 inch tall, so a counterbore just over 0.270 inch diameter and at least 0.164 inch deep takes it flush. That small footprint is the reason socket head screws get used where a Grade 5 or Grade 8 hex head would not have the surface area.

In this alloy steel socket head form, yes on tensile. The JSHC81 is rated 180,000 psi minimum tensile and 162,000 psi minimum yield, hardened to Rockwell C39, which the data states exceeds equivalent sizes of Grade 5 or Grade 8 hex head cap screws. If you need a wrench on the outside of the head instead of a hex key inside it, a hex head bolt is still the right call.

No. The JSHC81 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements, you need a domestically produced fastener.

It is internally wrenched with a hex (Allen) key, not a screwdriver or wrench flats. Socket depth is 0.077 inch, so the key needs to seat fully to avoid rounding the socket out at full torque.

They are built to ASME B18.3-2012, the standard for socket head cap screws, so head and socket geometry interchanges with any other B18.3 screw of the same size. The series is Metallics SHC.

The JSHC81 is plain alloy steel with a black finish, which is a decorative and mild in-service coating, not a corrosion barrier like zinc or stainless. Keep these to dry interior work: panels, enclosures, equipment mounting. For wet or exterior locations, specify a zinc plated or stainless fastener instead.

They ship in a jar of 100 pieces, and 100 is the order minimum. Jar weight comes in at 0.92 lbs.

Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. In practice an 8-32 x 1 inch socket head screw is enclosure, panel, strut accessory and equipment mounting hardware where a flush or recessed head is needed.

At 1 inch long, yes. Metallics notes that cap screws 3D or longer, where D is the nominal diameter, are subject to tensile, yield, elongation and reduction of area testing, and 1 inch far exceeds 3x an 8-32 diameter. Elongation is 10 percent minimum and reduction of area 33 percent minimum on machined specimens.
