Metallics JMBHC1220 – Frequently Asked Questions
1) What thread pitch does the Metallics JMBHC1220 M12 bolt have, and will it fit a standard M12 nut?
Thread pitch is 1.75 mm, which is the coarse standard for M12. It mates with any standard M12 coarse nut or tapped M12 x 1.75 hole. Fine-pitch M12 hardware (1.5 or 1.25) will not thread onto it.
2) Does the Metallics JMBHC1220 bolt meet Buy American or ARRA requirements for a government job?
No. The JMBHC1220 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, this bolt will not satisfy it.
3) Will a zinc plated steel M12 bolt hold up for outdoor strut and conduit work?
The JMBHC1220 is steel with a zinc finish, which is a dry-interior and sheltered-location plating. It handles indoor mechanical rooms, strut runs and equipment mounting fine. For wet, coastal or washdown exposure, step up to stainless rather than zinc plated steel.
4) What strength class is the Metallics M12 x 20 hex bolt rated to?
Tensile strength is 120,350 psi minimum with 95,700 psi minimum yield, and hardness runs Rockwell C23-34. That is a medium-carbon heat treated bolt, suitable for structural attachment of hangers, trapeze supports and equipment bases where a specific metric property class is not called out on the drawing.
5) How many bolts come in a jar of Metallics JMBHC1220, and can I buy fewer?
The JMBHC1220 ships as a jar of 50 pieces, and 50 each is the order minimum, so it is sold by the full jar rather than loose count. Metallics also offers other sizes and quantities in the MBHC and JMBHC bolt series by request.
6) What trades is the Metallics MBHC/JMBHC metric hex bolt line intended for?
Metallics lists this hex head metric bolt for the electrical, plumbing, heating and air conditioning industries, the typical use being fastening hangers, brackets, panels and equipment where a metric thread is required. It is a hex head bolt, driven with a wrench or socket, not a screwdriver bit.
