Metallics JSHC812 8-32 x 1/2 in. Socket Head Hex Cap Screws - Alloy Steel Black - Each

Yes. The JSHC812 is an 8-32 machine screw thread, 32 threads per inch, UN thread form, so it threads into any standard 8-32 tapped hole or nut. Usable length is 1/2 inch, so the hole needs at least that much depth plus whatever material you are clamping.

That is exactly what the socket head form is for. Because it is wrenched from inside the head rather than across flats, it needs less surrounding surface area or counterbore clearance than a hex head of the same size, and it still delivers higher tensile strength than equivalent Grade 5 or Grade 8 hex head cap screws. The JSHC812 is rated 180,000 psi minimum tensile and 162,000 psi minimum yield.

No. The JSHC812 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. On a job with domestic preference language, you will need a domestically sourced fastener instead.

It is internally wrenched with a hex (Allen) drive, with a socket depth of 0.077 inch. Head width runs 0.262 to 0.270 inch and head height 0.159 to 0.164 inch, which are the ASME B18.3 dimensions for a 8-32 socket head cap screw, so a standard 9/64 inch hex key is what fits the socket.

They come in a jar of 100. Minimum order is one jar, so 100 pieces is the smallest quantity. Jar weight is 0.47 lbs.

Head and thread dimensions conform to ASME B18.3-2012, the standard for socket cap screws. Material properties called out are 180,000 psi minimum tensile, 162,000 psi minimum yield, and Rockwell C39 hardness, with 10 percent minimum elongation and 33 percent minimum reduction of area on machined specimens.

Metallics lists the JSHC812 for electrical, plumbing, heating and air conditioning work. Typical use is mounting equipment, brackets, and panels where a counterbored or flush-pocket screw with high clamp load is needed in a 8-32 tapped hole.

Partly. Metallics notes that cap screws 3D or longer (D being nominal diameter) are subject to tensile, yield, elongation and reduction of area testing, and the elongation figure applies to machined specimens at least 4D long. For a #8 screw, 1/2 inch is well past 3D, so the strength values apply, though elongation and reduction of area are verified on machined specimens rather than the full-size screw.
