Metallics JMSBHC830 – Frequently Asked Questions
1) Is the Metallics JMSBHC830 M8 bolt coarse thread, and what nut will it take?
Thread pitch is 1.25 mm, which is the standard coarse pitch for M8, so it mates with any standard M8-1.25 nut or tapped hole. Threads are cut to ISO 724 and ISO 965-1, so tolerance class is the normal metric fit rather than a proprietary thread.
2) Will these M8 stainless bolts hold up outdoors or in a damp mechanical room?
The material is 18-8 stainless steel to ISO 3506, property class A2. A2 handles outdoor, washdown, and damp interior service well. For chloride exposure, coastal air, or pool chemistry, step up to A4 (316) stainless instead.
3) What wrench or socket fits the head on the Metallics JMSBHC830?
It is a hex head bolt to DIN 933. At M8 under that standard the across-flats size is 13 mm, so a 13 mm socket or wrench is what you reach for. Wrenching height on the head is 3.61.
4) How does the JMSBHC830 ship, and is there a minimum order quantity?
These come packaged in a jar of 100 pieces, and 100 count is the order minimum, so you buy by the jar rather than loose. Jar weight is 1533 g. Metallics lists other sizes and quantities in the JMSBHC series by request.
5) Do these bolts meet Buy American or ARRA requirements on a public project?
The JMSBHC830 is flagged compliant for both ARRA and Buy American in the manufacturer data, with country of origin listed as China. On a federally funded job, submit the manufacturer compliance statement with your package since fastener rules vary by funding program.
6) Is an M8 x 30 stainless hex bolt long enough for strut channel and electrical mounting?
At 30 mm of fully threaded length, it suits strut and channel hardware, equipment feet, enclosure and tray mounting where total grip plus nut is roughly an inch or less. Thicker stacks need a longer bolt; Metallics builds the JMSBHC series in other lengths.
7) Can I mix these stainless bolts with galvanized or plain steel nuts and washers?
Better not to. A2 18-8 stainless paired with zinc or plain carbon steel in a wet location sets up galvanic action and the coated part corrodes first. Keep the nut and washers in the same A2 stainless family for the joint to age evenly.
