Metallics JMSBHC1240 – Frequently Asked Questions
1) What thread pitch is the Metallics JMSBHC1240 M12 bolt, and will it take a standard M12 nut?
It's M12 x 1.75, which is the coarse metric pitch, so it mates with any standard coarse M12 nut or tapped M12 hole. Threads are cut to ISO 724 and ISO 965-1. If your hole or nut is a fine pitch (1.5 or 1.25), this bolt will not thread into it.
2) Does the JMSBHC1240 bolt meet Buy American and ARRA requirements for a public project?
Metallics lists the JMSBHC1240 as compliant for both Buy American and ARRA. Country of origin is China, so if your specification demands domestic melt and manufacture rather than ARRA/BAA compliance as flagged here, confirm which standard the job is written to.
3) Is a stainless M12 bolt like this strong enough to replace a Grade 5 or Grade 8 steel bolt?
No. This is A2 18-8 stainless under ISO 3506, which is a corrosion-resistant class, not a high-strength class. If the connection is engineered for a Grade 5 or Grade 8 (or metric 8.8/10.9) bolt, do not substitute stainless without the engineer signing off.
4) What size wrench or socket fits the head on this M12 hex bolt?
Per the DIN 933 spec referenced for these bolts, maximum width across flats on an M12 is 19 mm, so a 19 mm wrench or socket is the one to grab. The head is a standard hex.
5) Is this stainless bolt suitable for outdoor or damp electrical work?
The bolt is 18-8 stainless steel, A2 class under ISO 3506, so it handles general outdoor and damp-location service without plating. For saltwater or heavy chloride exposure, A4 (316) stainless is the better choice.
6) How many bolts come in a jar of Metallics JMSBHC1240, and is there an order minimum?
Each jar holds 50 bolts, and 50 count is the order minimum, so the jar is the smallest buy. Jar weight is 2404 g. Metallics notes other sizes and quantities are available by request.
7) Do nuts and washers come with the Metallics JMSBHC1240 jar?
The jar is bolts only, 50 hex head bolts, no nuts or washers. Order matching M12 x 1.75 coarse stainless nuts and flat washers separately so the hardware matches for corrosion resistance.
