Metallics JBBH91 – Frequently Asked Questions
1) Is the Metallics JBBH91 a fine thread or coarse thread 1/4 inch bolt?
Fine thread. The JBBH91 is a 1/4-28 hex bolt, 28 threads per inch, cut to ANSI/ASME B1.1. That is 1/4 inch UNF, so it will not thread into a 1/4-20 coarse nut or tapped hole. If the mating part is 1/4-20, you need a coarse bolt instead.
2) What is the Metallics JBBH91 hex bolt made of, and will it corrode in a wet or grounding application?
Silicon bronze, with a bronze finish, made to ASTM F468 for nonferrous fasteners. Silicon bronze is the usual choice where a fastener has to resist corrosion and stay compatible with copper and bronze hardware, which is why it turns up on grounding connections, marine work, and outdoor assemblies. Bolting silicon bronze to copper avoids the galvanic mismatch you get with a plated steel bolt.
3) Does the Metallics JBBH91 bolt meet Buy American and ARRA requirements on a federal job?
The JBBH91 is flagged compliant for both Buy American and ARRA. Country of origin is China, so if your specification requires domestic melt and manufacture rather than ARRA/Buy American compliance as recorded here, confirm which standard the contract actually cites.
4) How does the Metallics JBBH91 ship, and what is the minimum I can order?
It comes as a jar of 100 bolts, and 100 count is the order minimum. Jar weight is 1.99 lbs, and the container measures 3 x 2.7 x 3 inches. Other sizes and quantities are available by request.
5) What is the difference between the Metallics BBH and JBBH part numbers?
Same bolt, different packaging. The JBBH prefix, as on JBBH91, is the jar-packed version of the BBH and JBBH silicon bronze hex bolt line. If you are stocking a shop drawer or a service van, the jar of 100 is the one to order.
