Metallics JMSHC412SS – Frequently Asked Questions

1) What size hex key do I need to drive these M4 socket cap screws?
A 3 mm hex key. The socket measures 3.020 to 3.071 mm across the flats, which is the standard 3 mm drive for an M4 socket head cap screw. There is no external wrenching surface, so the hex key is the only way to drive them, and you need clearance above the head to get the key in.
2) Will a 12mm long M4 screw be long enough for my application?
At 12 mm overall under-head length, these give you roughly 12 mm minus your material thickness in thread engagement. For a tapped hole you generally want at least one screw diameter of engagement, so 4 mm for M4, meaning this length suits clamped material up to about 8 mm thick. Thicker stacks need a longer M4. Metallics offers other MSHC lengths and sizes by request.
3) Are these stainless screws OK for outdoor or damp electrical enclosures?
The JMSHC412SS cap screws are 18-8 stainless, the common austenitic grade used where plated carbon steel would rust, so they hold up in damp interiors, outdoor enclosures, and washdown areas. For direct, constant salt spray or coastal marine exposure, 316 stainless is the step up. Pair them with stainless washers and nuts, not plated steel, to avoid setting up a galvanic couple.
4) How do these ship, and is there a minimum order quantity?
They come packed in a jar, with a minimum order of 100 count. So you are buying a 100-piece jar rather than loose pieces, which is how shops normally stock a single M4 length for panel and enclosure work.
5) Do these screws meet Buy American or ARRA requirements on a federal job?
The JMSHC412SS is flagged compliant for both Buy American and ARRA in Metallics' data, with country of origin listed as China. On a federally funded project, submit that compliance flag with the origin to your specifier, since domestic-content rules differ by contract type.
6) Is a socket head cap screw the right choice over a hex head bolt for enclosure and panel mounting?
A socket head like the MSHC series drives from the top with a hex key, so it works where a wrench or socket cannot swing: inside enclosures, in counterbored holes, and against a wall or adjacent equipment. A hex head bolt is the better pick when you need high torque or you are working blind by feel with a wrench. Trade-off is access above the head, since the key must seat fully in the socket.
7) How much does a jar of the M4 x 12mm Metallics cap screws weigh for shipping?
0.48 lbs for the jar. Handy if you are building out a kit weight or consolidating a fastener order with heavier items.
