Metallics JMBHC1290 Bolts M12 X 90 Hxbt St-zn (Jar 50)

It's an M12 metric hex bolt with a 90mm shank length, made to DIN 931, which is the partially threaded hex cap screw standard. Partially threaded means a plain shoulder under the head with thread only at the business end, so it carries shear across a joint better than a fully threaded bolt. If your drawing calls for full thread the full length, DIN 931 is not the right standard for you.

Rated at 120,350 psi minimum tensile and 95,700 psi minimum yield, with a hardness of Rockwell C23-34. Those are the figures you hand to an engineer checking a bolted connection. If a spec sheet asks for a lower-strength commercial bolt, this exceeds it; if it calls for a high-strength structural bolt above that tensile figure, look elsewhere.

No. The JMBHC1290 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project has domestic-content language in the contract, this bolt will not clear it and you need a domestically sourced M12.

The bolt is steel with a zinc finish. Zinc plating handles indoor and sheltered conditions and resists handling corrosion in a panel or raceway, but it is not a hot-dip galvanized or stainless part. For direct weather exposure, wet locations, or coastal work, specify a galvanized or stainless M12 instead.

It's a hex head bolt, and on an M12 to DIN 931 the across-flats figure is 18 to 19, so a 19mm socket or wrench is what crews normally reach for. Keep that in mind if you're working in a tight enclosure, a standard 19mm six-point will need swing room.

Fifty bolts in a jar, and 50 each is also the order minimum, so a jar is the smallest buy. The jar format suits a service van or a shop bin where you're pulling a handful at a time. Metallics also offers other sizes and quantities of this hex bolt by request.

The 90mm figure is the shank under the head, not overall with the head, so the material you clamp plus the nut and washer stack has to fit inside that 90mm. On a DIN 931 bolt part of the shank is unthreaded, so keep the joint line in the plain section and leave enough thread for the nut to fully engage. If your stack is close to 90mm, step up to the next length rather than running the nut off the end of the thread.

No. The jar holds M12 x 90 hex bolts only. Nuts, flat washers, and lock washers in M12 are separate line items, so add them to the order if you're building a complete bolted assembly.
