Metallics JBBH85 – Frequently Asked Questions
1) What thread and size is the Metallics JBBH85 hex bolt?
It's a 5/8-11 hex bolt, 5 inches long. The 11 threads per inch is the standard UNC coarse pitch for 5/8 inch diameter, cut to ANSI/ASME B1.1, so it mates with any standard 5/8-11 nut or tapped hole. Head width across flats runs 0.922 to 0.938 inch, which is a 15/16 inch wrench.
2) Why use a silicon bronze bolt instead of galvanized or stainless steel?
Silicon bronze is the grounding and marine-exposure choice. It resists corrosion in wet and buried conditions and, being a copper alloy, it won't set up galvanic corrosion against copper grounding conductors, bronze ground clamps, or copper-alloy water piping the way zinc-plated or galvanized steel will. The JBBH85 is silicon bronze to ASTM F468 with a bronze finish. If you're bolting plain steel structure in a dry interior, a zinc-plated steel hex bolt is the cheaper correct answer.
3) Do these bronze bolts meet Buy American or ARRA requirements for a public project?
No. The JBBH85 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-sourcing clause, this part won't satisfy it.
4) What trades actually use these 5/8 inch bronze hex bolts?
Metallics lists the BBH and JBBH bolts for the electrical, plumbing, heating and air conditioning industries. In practice that means grounding and bonding connections, bronze pipe hangers and supports, and anywhere a corrosion-resistant copper-alloy fastener is called out instead of plated steel.
5) How many bolts come in a jar of Metallics JBBH85, and can I buy just a few?
The JBBH85 ships as a jar of 25, and 25 each is the order minimum, so it's sold by the jar rather than the piece. Metallics does offer other sizes and quantities on request.
6) Will the JBBH85 head fit a standard hex socket, and how much head height does it add?
Head width across the flats is 0.922 to 0.938 inch, so a 15/16 inch socket or wrench drives it. Head height is 0.378 to 0.403 inch, which is what to allow for clearance under a cover plate or inside an enclosure.
7) Is this hex bolt made to a recognized dimensional standard so it interchanges with other brands?
Dimensions follow ASME B18.2.1, the standard for square and hex bolts and screws, and threads follow ANSI/ASME B1.1. Any other 5/8-11 x 5 hex bolt built to B18.2.1 will drop into the same hole pattern and take the same nut, so grip length and wrench clearance carry over.
8) Does a jar of JBBH85 come with nuts and washers?
No. The JBBH85 is bolts only, 25 hex bolts to the jar. Order matching 5/8-11 silicon bronze hex nuts and bronze washers separately if you want the whole assembly in the same alloy, which is what keeps the joint free of dissimilar-metal corrosion.
9) How much does a jar of 25 of these 5/8 inch bronze bolts weigh for shipping?
Metallics lists the packed weight at 42.75 lbs for the jar of 25, with the carton at 4.5 by 4.5 by 7.25 inches. Worth knowing if you're staging several jars on a lift or a cart.
