Metallics JBBH84 – Frequently Asked Questions
1) Is the Metallics JBBH84 hex bolt solid silicon bronze or just bronze plated?
Solid silicon bronze all the way through, not a plated steel bolt. The material is listed as Silicon Bronze with a bronze finish, and it is made to ASTM F468, the standard covering nonferrous bolts and studs for general use. That is why it gets specified for grounding connections, water contact, and corrosive environments where a zinc-plated steel bolt would rust out.
2) What thread does the 5/8-11 silicon bronze hex bolt have, and will it take a standard 5/8 nut?
It is 5/8-11, meaning 11 threads per inch, cut to ANSI/ASME B1.1. That is standard 5/8 UNC coarse thread, so any off-the-shelf 5/8-11 nut threads on. For a bronze bolt in a corrosive or grounding application, pair it with a silicon bronze nut rather than a plated steel one so you are not mixing metals at the joint.
3) Is this bolt approved for a Buy American or ARRA-funded project?
No. The JBBH84 silicon bronze hex bolt is listed as not Buy American compliant and not ARRA compliant, with a multi-country origin. If you are buying for a federally funded job with domestic sourcing requirements, this part will not satisfy the clause and you need a domestic-origin silicon bronze fastener instead.
4) What wrench or socket size fits the head on the Metallics JBBH84 bolt?
The head measures 0.922 to 0.938 inches across the flats, so a 15/16 inch socket or wrench is the fit. Head height runs 0.378 to 0.403 inches. The bolt is a standard hex head built to ASME B18.2.1, so dimensions match any other B18.2.1 5/8 hex bolt you already have on the job.
5) How many bolts come in a jar of Metallics JBBH84, and can I buy just a few?
It ships as a jar of 50 pieces, and 50 each is the order minimum, so it is sold by the jar rather than loose by the piece. The JBBH prefix is the jar-packed version of the BBH silicon bronze hex bolt series. Other sizes and quantities are available by request if 4-1/2 inch length or a 50-count jar is not what the job needs.
6) Where are silicon bronze hex bolts like the Metallics JBBH84 typically used?
Metallics lists the field application as the electrical, plumbing, heating and air conditioning trades. In practice that means grounding and bonding hardware, pipe hangers and supports, and anywhere a fastener sits in damp or chemically aggressive conditions. Silicon bronze is chosen for its corrosion resistance and conductivity, which is why it shows up on ground plates and water-side equipment rather than on dry structural steel, where a plated or galvanized steel bolt is the normal call.
7) How heavy is a jar of 50 Metallics 5/8-11 x 4-1/2 silicon bronze bolts?
The jar weighs 39.35 lbs. Worth knowing if you are ordering several jars for a large grounding or hanger package, since bronze is noticeably heavier per piece than a steel bolt of the same size and the pallet count adds up fast.
