Metallics JMSBHC88 – Frequently Asked Questions
1) What thread pitch do these M8 bolts have, and will they thread into a standard M8 nut?
The thread is M8 with a 1.25 mm pitch, which is the coarse metric standard, and it is cut to ISO 724 and ISO 965-1. Any standard coarse M8 nut or M8 x 1.25 tapped hole will take it. A fine-pitch M8 x 1.0 nut will not.
2) Are these stainless bolts suitable for outdoor or damp electrical installations?
They are 18-8 stainless steel, property class A-2 to ISO 3506, so they handle outdoor, damp, and washdown locations where plated carbon steel would rust. For salt spray, chlorides, or coastal exposure, step up to 316 stainless instead; A-2 is the general-purpose corrosion grade, not the marine one.
3) How many bolts come in a jar and can I buy fewer than that?
The M8 x 40 stainless hex bolts ship 100 to a jar, and 100 count is the order minimum, so the jar is the smallest unit. Other sizes and quantities can be requested.
4) Do these Metallics bolts meet Buy American and ARRA requirements for a government or institutional job?
The JMSBHC88 record carries both an ARRA compliant and a Buy American compliant flag, while country of origin is listed as China. If your specification is a strict domestic-melt requirement rather than the ARRA compliance flag, confirm which clause your contract is written to before you submit the bolt for approval.
5) Are nuts or washers included with the JMSBHC88 jar?
The jar holds bolts only, 100 of the M8 x 40 hex bolts. Order matching A-2 stainless M8 nuts and washers separately; mixing in plated carbon steel nuts on a stainless bolt gives you dissimilar metals at the joint and defeats the point of specifying stainless.
6) Will these bolts gall or seize when I run the nut down?
18-8 stainless is prone to thread galling, especially if you drive the nut fast with an impact. Run A-2 stainless fasteners down slowly, and use an anti-seize on the threads when you are torquing to spec. This is a property of the material, not a defect in the bolt.
