Metallics JBBH59 – Frequently Asked Questions
1) Is the Metallics JBBH59 hex bolt suitable for outdoor or wet locations like grounding and marine work?
Silicon bronze is the material, which is why these get specified for corrosion-prone work such as grounding connections, water and wastewater structures, and exterior anchoring. The material conforms to ASTM F468, the standard covering nonferrous bolts for general use. The bronze finish is the natural material color, not a plating that can wear off.
2) What thread does the Metallics JBBH59 bolt use, and will a standard 3/8-16 nut thread onto it?
It is a 3/8-16 bolt, 16 threads per inch, cut to ANSI/ASME B1.1. That is standard UNC coarse thread, so any 3/8-16 nut or tapped hole will take it. For corrosion work, pair it with a silicon bronze nut and washer rather than a plated steel one, so you are not mixing dissimilar metals at the joint.
3) Can I use the Metallics JBBH59 bronze bolt on a federally funded Buy American project?
No. The JBBH59 is listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. If your contract carries domestic sourcing language, you will need a documented domestic-origin bronze fastener instead.
4) How is the Metallics JBBH59 3/8-16 x 1-1/4 bronze bolt packaged, and is there a minimum order?
They ship in a jar of 100 pieces, and the jar is the order unit, so 100 is the minimum. Jar weight is listed at 5.255 lbs. Other sizes and quantities can be had by request.
5) What trades use silicon bronze hex bolts like the Metallics JBBH59?
Electrical, plumbing, heating and air conditioning work is the stated field application. In practice that means grounding and bonding hardware, pipe supports and hangers in damp areas, and equipment mounting where a plated steel bolt would rust out or set up galvanic corrosion against copper or bronze components.
