Metallics JSHC14112SS – Frequently Asked Questions
1) What size and thread is the Metallics JSHC14112SS socket head cap screw?
It's a 1/4-20 x 1-1/2 inch socket head cap screw. The 1/4-20 means a 1/4 inch nominal diameter with 20 threads per inch, which is the standard coarse (UNC) pitch for that diameter, so it mates with any 1/4-20 nut or tapped hole. The 1-1/2 inch is the shank length under the head.
2) Is the JSHC14112SS screw stainless steel, and what grade?
Yes, 18-8 stainless steel. That's the austenitic 300-series grade (roughly 18% chromium, 8% nickel) used for general corrosion resistance in damp interior work, outdoor enclosures, and wet locations. It is non-magnetic and will not rust the way a plated carbon steel screw does, which is why it gets specified for electrical mounting where galvanized hardware would bloom.
3) Do nuts and washers come with the Metallics JSHC14112SS screws?
No, the jar of 100 is screws only. If you're through-bolting, order 1/4-20 nuts and 1/4 inch washers separately, and match them in 18-8 stainless so you don't set up a dissimilar metal pairing with plated steel hardware.
4) What kind of driver do I need for a 1/4-20 socket head cap screw like this?
A hex key, not a screwdriver. SHCS means socket head cap screw, so the head is cylindrical with an internal hex socket and it's driven with an Allen wrench or a hex bit. The recess lets you get high torque in a tight spot where a wrench can't reach a hex head, which is the usual reason it gets picked for equipment and enclosure mounting.
5) Should I use a socket head cap screw or a hex head bolt for mounting equipment in an enclosure?
Go socket head where clearance is the problem. The JSHC14112SS has a cylindrical head with an internal hex drive, so it seats close to the surface and needs only straight-down access for the key, no swing room for a wrench. A hex head bolt is faster to run with a socket or impact and easier to grab if it has to come apart often, but it needs side clearance. In a crowded panel or against a wall, the socket head wins.
6) Can the Metallics JSHC14112SS be used outdoors or in a wet location?
The 18-8 stainless material handles general outdoor and damp-location exposure without plating, which is why it's used on exterior enclosures, strut, and rooftop equipment mounts. It is not the grade to reach for in direct salt spray or chemical service; 316 stainless is the step up for marine and coastal work.
