Metallics JMBHC512 – Frequently Asked Questions
1) How strong are these M5 hex bolts, and are they hardened?
Rated 116,000 psi minimum tensile and 92,800 psi minimum yield, with a hardness of Rockwell C22-32. That puts them in medium-carbon heat-treated territory rather than plain low-carbon, so they'll take real torque in strut, enclosure, and equipment-mounting work. Steel body with a zinc finish.
2) Will the JMBHC512 satisfy a Buy American or ARRA requirement on my job?
The record flags the JMBHC512 as compliant for both ARRA and Buy American, with country of origin listed as China. If your contract has a strict domestic-melt or domestic-manufacture clause rather than the ARRA fastener treatment, confirm which rule your spec is written to before you submit it.
3) Is an M5 bolt the same as a 10-32 or 1/4-20 machine screw?
No. M5 is metric, roughly 0.197 inch across the thread, and it won't thread into an imperial 10-32 or 1/4-20 nut or tapped hole. If your existing hardware is imperial, order imperial. The JMBHC512 is built to the metric DIN 931 standard and only mates with M5 threads.
4) Is the M5 x 12 Metallics bolt fully threaded or does it have a plain shank?
The dimensional standard called out is DIN 931, which is the partially threaded hex bolt spec (plain shank under the head, thread on the end). At a 12mm overall length though, the unthreaded run is minimal. If your application needs thread engagement right up to the head, say so when ordering, since other sizes and quantities in the MBHC/JMBHC series are available by request.
5) Can I use zinc-plated M5 bolts outdoors or in a wet location?
Zinc plating on steel is a mild corrosion barrier, fine for indoor and dry or damp protected locations, panel interiors, and general MRO work. For sustained outdoor exposure, washdown areas, or anywhere near chlorides, zinc plating will eventually sacrifice and the steel will rust. Specify stainless in that case.
6) How many bolts come in a jar, and is there a minimum order?
They ship 100 to a jar, and 100 count is the order minimum, so one jar is the smallest buy. The jar packaging holds up better on a service truck than a poly bag and keeps loose M5 hardware from migrating through a van drawer. Jar weight is listed at 358 g.
7) What else do I need to order with these M5 x 12 hex bolts?
Bolts only, nothing else in the jar. Plan on M5 nuts and M5 flat or lock washers to suit, matched in zinc so you aren't mixing platings in one joint. Other sizes and quantities in the MBHC and JMBHC series can be had by request if 12mm is short for your stack-up.
