Metallics JBBH43 – Frequently Asked Questions
1) What thread and size is the Metallics JBBH43 hex bolt, and will it take a standard 5/16-18 nut?
The JBBH43 is a 5/16-18 hex bolt, 1 inch long, with 18 threads per inch cut to ANSI/ASME B1.1. That is the standard Unified coarse thread for 5/16 diameter, so any standard 5/16-18 nut or tapped hole mates with it. Body dimensions follow ASME B18.2.1 for hex bolts.
2) Is the JBBH43 bolt actually bronze, or just bronze plated?
Solid silicon bronze, not a plated steel bolt. The material is specified to ASTM F468, the standard covering nonferrous bolts for general use, and the finish reads bronze because that is the base metal. That matters for outdoor grounding, marine, and wet-location work where a plated fastener would eventually rust through its coating.
3) Does the Metallics JBBH43 bolt meet Buy American or ARRA requirements for a public project?
No. The JBBH43 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your job carries a domestic-content clause, this bolt will not satisfy it.
4) What wrench or socket size fits the head of the Metallics 5/16-18 silicon bronze hex bolt?
Head width across flats runs 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the one you want. Head height is 0.195 to 0.211 inch.
5) How many bolts come in a jar of Metallics JBBH43, and can I buy fewer?
They ship in a jar of 100, and 100 (one jar) is the order minimum, so the jar is the smallest unit. Other sizes and quantities are available by request. The packed jar weighs 3.27 lbs.
6) Can I use silicon bronze hex bolts for electrical grounding connections?
Yes. The JBBH43 is intended for the electrical, plumbing, heating and air conditioning trades, and silicon bronze is the conductive, corrosion-resistant material commonly specified for ground clamps, bonding lugs and buried or damp-location connections where steel would corrode and loosen the joint.
7) Should I use silicon bronze or stainless steel bolts outdoors?
Both resist corrosion, but they are not the same choice. Silicon bronze like the JBBH43 is preferred where the bolt contacts copper or bronze hardware, in marine and buried settings, and on grounding work, because it will not set up the galvanic couple that stainless can against copper and it does not gall the way stainless threads do. Stainless is the pick for higher strength requirements. This bolt is bronze throughout, per ASTM F468.
