Metallics JMSBHC125 – Frequently Asked Questions
1) What size and thread does the Metallics JMSBHC125 hex bolt use?
It is an M12 x 40 hex head bolt with a 1.75 mm thread pitch, which is standard coarse metric for M12. Threads are made to ISO 724 and ISO 965-1, so it mates with any standard M12 x 1.75 nut or tapped hole.
2) Will stainless hex bolts like this corrode in outdoor or damp electrical enclosures?
These are 18-8 stainless steel, property class A-2 under ISO 3506. A2 stainless handles outdoor, damp, and washdown conditions well. For coastal salt spray or chloride exposure, step up to 316 (A4) stainless instead.
3) How are these M12 x 40 stainless bolts packaged, and what is the minimum order?
They ship in a jar of 100 pieces, and 100 count is the order minimum. That is a single jar per line, so a crew stocking a van or a shop bin buys in 100-piece increments rather than loose counts.
4) What wrench or socket do I need for these metric hex bolts?
Across flats is governed by DIN 933. Metallics lists maximum width across flats of 17, 19 and 22 mm for the three diameters in the JMSBHC family, so you will be working with metric sockets in that range rather than inch sizes. Keep a metric set on the job; an inch socket will round the head.
5) Can I use these stainless bolts in aluminum strut and enclosures without galvanic problems?
18-8 stainless against aluminum is a galvanic pair, so in wet or outdoor locations isolate with a nylon or stainless washer set and keep the joint dry or sealed. Dry indoor enclosures are not a concern. If the assembly is continuously wet, a coated or isolated fastener is the safer call.
6) Are Metallics JMSBHC125 bolts domestic or imported?
Country of origin is China. The record flags the item as ARRA compliant and Buy American compliant, so it has been coded against those programs, but on federally funded work verify the origin requirement for your specific contract before you specify it.
7) Can I get this hex bolt in other lengths or diameters, or in a different pack size?
The JMSBHC series covers additional diameters and lengths, and other quantities are available by request rather than as stock jar counts. Metallics lists across-flats maximums of 17, 19 and 22 mm for the three diameters in the family, so the series spans a range of sizes around this M12.
