Metallics JMBHC1245 – Frequently Asked Questions
1) How strong is this M12 hex bolt, and what grade does it correspond to?
Rated at 120,350 psi minimum tensile and 95,700 psi minimum yield, with a hardness of Rockwell C23-34. Those figures line up with a property class 8.8 medium carbon steel bolt, which is the usual metric structural fastener for strut, hangers, and equipment mounting.
2) Can I use these bolts on a federally funded job with Buy American requirements?
No. The JMBHC1245 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a project with domestic sourcing requirements on fasteners, this bolt will not qualify.
3) Will zinc plated steel bolts hold up outdoors or in a damp mechanical room?
The JMBHC1245 is zinc plated carbon steel, which is a coating meant for dry indoor and sheltered service. It handles a mechanical room or interior strut work fine. For sustained wet exposure, coastal air, or chemical washdown, step up to an 18-8 stainless M12 hex bolt in the same Metallics hex head metric bolt program rather than using zinc plate.
4) How many bolts come in a jar of Metallics JMBHC1245, and can I buy fewer than that?
They ship 50 pieces to a jar, and 50 each is the order minimum, so the jar is the smallest buy. Total shipping weight for the jar is 2,350 g. If you need a different count or a different M12 length, Metallics runs other sizes and quantities in the MBHC and JMBHC series.
5) Does the jar of JMBHC1245 bolts include nuts and washers?
Bolts only, 50 to the jar. Nuts and flat or lock washers have to be ordered separately in M12 x 1.75 to match the thread.
6) Are these M12 bolts intended for electrical and mechanical trade work or for structural steel?
Metallics lists this hex bolt for the electrical, plumbing, heating and air conditioning trades, so the intent is equipment mounting, hanger and strut assembly, panel and enclosure anchoring. It isn't sold as a structural steel connection bolt, and structural bolted joints are specified to their own standards, not DIN 931.
