Metallics JMSBHC834 – Frequently Asked Questions
1) What thread pitch do these M8 stainless hex bolts use, and will they take a standard M8 nut?
Thread pitch is 1.25 mm, which is the coarse M8 pitch, and the threads are cut to ISO 724 and ISO 965-1. Any standard coarse M8 nut or M8 x 1.25 tapped hole will accept them. They will not thread into an M8 x 1.0 fine-pitch hole.
2) What grade of stainless are these Metallics hex bolts, and will they hold up outdoors?
The material is 18-8 stainless steel, classified A-2 under ISO 3506. A2/18-8 handles outdoor, damp, and washdown service and most general exterior electrical work. In chloride-heavy environments, coastal exposure, pool rooms, or chemical plants, step up to 316 (A4) stainless instead, since A2 can pit in those conditions.
3) What wrench or socket size fits the head on the JMSBHC834 M8 bolt?
It is a hex head sized to DIN 933 for M8, which takes a 13 mm wrench or socket. The listed head width across flats runs 12.73 to 13, and head height is 5.15 to 5.45.
4) How many bolts come in a jar and can I order fewer than that?
They ship as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit you can buy. Metallics does offer other sizes and quantities in the JMSBHC series by request.
5) Do these bolts meet Buy American or ARRA requirements for a federal or municipal job?
Metallics lists the JMSBHC834 as compliant for both ARRA and Buy American purposes. Country of origin is China. On a federally funded project, hand both of those facts to your specifying authority, since the applicable rule depends on the funding program for your job.
6) Will these stainless bolts cause a corrosion problem bolted to galvanized or aluminum?
18-8 stainless is cathodic to both zinc coating and aluminum, so in a wet exterior location the galvanized or aluminum part corrodes preferentially around the fastener. Indoors and dry it is a non-issue. Outdoors, isolate with a nylon or neoprene washer, or match the fastener material to the part.
7) How much does a jar of 100 of these M8 x 20 stainless bolts weigh?
The packaged jar weighs 1216 g. Useful if you are planning a shipment or loading out a service van with several sizes.
