Metallics JBBH16 – Frequently Asked Questions
1) Is the Metallics JBBH16 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 to ASTM F468, and the finish is bronze. That matters for grounding and marine or corrosive work where a plated fastener would fail once the coating is scratched.
2) What thread does the JBBH16 bolt take, and will a standard 5/16 nut thread on?
It is 5/16-18, which is 18 threads per inch cut to ANSI/ASME B1.1, the standard Unified coarse thread. Any standard 5/16-18 UNC nut will thread on. For full galvanic match on a bronze installation, pair it with a silicon bronze nut rather than a plated steel one.
3) Can I use these bolts on a federally funded project with Buy American requirements?
No. The JBBH16 is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. On a job with domestic sourcing requirements you need a domestically produced silicon bronze bolt instead.
4) What wrench or socket size fits the head on this 5/16-18 hex bolt?
The head measures 0.489 to 0.500 inches across the flats, so a 1/2 inch wrench or socket is the fit. Head height runs 0.195 to 0.211 inches. Head dimensions follow ASME B18.2.1, so it sits in standard hex bolt clearances.
5) How is the JBBH16 packaged, and is there a minimum order?
It ships as a jar of 100 bolts, and the jar is the minimum order unit. Jar weight is 7.14 lbs. If you need a different size or a different count, Metallics offers other sizes and quantities in the BBH and JBBH series by request.
6) Why would an electrician choose a silicon bronze bolt over a galvanized steel one?
Silicon bronze is non-ferrous and conductive, so it is the usual pick for grounding connections, bonding jumpers, and wet or corrosive locations where zinc plating gives up. Metallics lists this bolt for electrical, plumbing, heating and air conditioning work. For dry interior framing where corrosion and conductivity are not factors, a plated steel hex bolt does the same mechanical job.
