Metallics JMSHC520SS – Frequently Asked Questions

1) What thread size and pitch is the Metallics JMSHC520SS socket cap screw?
It's an M5 coarse thread with a 0.8 mm pitch, 20 mm long. That is the standard M5 coarse pitch, so it threads into any M5 x 0.8 tapped hole or standard M5 nut. If your tapped hole is a fine-pitch M5, this screw won't run in it.
2) Can I use these screws outdoors or in a wet location?
The JMSHC520SS is made from 18-8 stainless, so it holds up in damp and outdoor service far better than a plain-finish steel screw. It's a common choice for exterior enclosures, strut, and mounting hardware exposed to weather. For chloride-heavy environments like coastal or pool rooms, 316 stainless is the step up from 18-8.
3) How many screws come in a jar and is there a minimum order?
These M5 x 20 mm socket cap screws ship in a jar, with a minimum order of 100 count. The filled jar weighs 0.95 lbs, which is useful if you're totalling shipping weight on a larger fastener order.
4) What dimensional standard do these metric socket head cap screws conform to?
Head and socket geometry follow ISO 4742. If your drawing or panel spec calls out an ISO metric socket head cap screw, the head will sit in a counterbore machined to that standard rather than to an SAE inch dimension.
5) Is the head on this screw a hex head or a socket head?
Socket head with an internal hex drive, not an external hex you'd put a wrench on. That matters for clearance: the head sits in a tight bore or against a flat with no need for wrench swing, which is why these get used inside panels and enclosures and on strut where a box wrench won't fit.
6) Do these screws meet Buy American and ARRA requirements for a federal job?
The JMSHC520SS carries both ARRA Compliant and Buy American Compliant flags in its product record, with country of origin listed as China. For a federally funded project, pull those two compliance designations into your submittal package along with the origin so the reviewing authority has what it needs on file.
