Metallics JSHC834SS – Frequently Asked Questions
1) How many 8-32 x 3/4 in. socket head cap screws come in a jar of Metallics JSHC834SS?
The JSHC834SS ships as a jar of 100, and 100 count is the order minimum. So the smallest buy is one 100-piece jar rather than loose pieces.
2) Will an 8-32 stainless cap screw thread into a standard 8-32 tapped hole or nut?
Yes. The thread is UNC at 32 threads per inch in a #8 nominal diameter, which is the standard coarse 8-32 machine thread, so it mates with any 8-32 tapped hole, nut, or insert. The screw is made to ASME B18.3-2012 dimensional standard for socket head cap screws.
3) What strength can I count on from an 18-8 stainless 8-32 socket head screw?
Rated 80,000 psi minimum tensile and 30,000 psi minimum yield, with hardness at Rockwell B80. Elongation is 10 percent minimum and reduction of area 33 percent minimum. That is stainless-grade strength, lower than an alloy steel black-oxide socket screw, so if your drawing calls for a high-strength alloy cap screw this is not a drop-in substitute.
4) What size hex key drives an 8-32 socket head cap screw?
It takes a hex (Allen) key, driven from a recessed socket in the head. The socket depth is 0.077 in. and the head measures 0.262 to 0.270 in. across with a height of 0.159 to 0.164 in., so you need clearance for a key that fits inside that head, not an external wrench.
5) Are these stainless cap screws OK outdoors or in damp electrical enclosures?
They are 18-8 stainless, the common austenitic grade used where plain steel would rust, so they hold up in wet and outdoor enclosure work. Metallics also notes they keep their mechanical and performance capabilities above ambient temperature, which matters in hot equipment rooms and near ballast or driver heat.
6) Do these Metallics cap screws qualify for a Buy American or ARRA-funded job?
Metallics lists the JSHC834SS as both Buy American compliant and ARRA compliant. Country of origin is shown as multiple, so if your spec requires a single named country of manufacture, confirm the lot before you submit documentation.
7) Is a socket head cap screw the right choice over a slotted or Phillips machine screw for panel work?
A socket head takes an internal hex key, so you can put real torque on it without camming out the way a slotted or Phillips driver does, and the cylindrical head sits in a counterbored hole where a pan head would not. Trade-off is access: you need straight-on room for the Allen key, and the head is only 0.262 to 0.270 in. across, so there is no flat for a wrench if the key access is blocked.
8) Can I get this socket head cap screw in other lengths or larger quantities?
Yes. Metallics states other sizes and quantities in the SHC socket head cap screw line are available by request beyond the 8-32 x 3/4 in. 100-count jar.
9) How much does a jar of 100 of these 8-32 screws weigh for shipping or a stockroom bin?
The jar comes in at 0.58 lbs with listed pack dimensions of 3 x 3 x 2.15 in., which fits a small parts bin without repackaging.
