Metallics JBBH35 – Frequently Asked Questions
1) Is the Metallics JBBH35 hex bolt silicon bronze all the way through, or just bronze plated?
Solid silicon bronze, not a plating. The JBBH35 is made to ASTM F468, the standard covering nonferrous bolts and studs, and the finish is bronze throughout. That is why it gets used in wet, buried, and grounding applications where a plated steel bolt would corrode away.
2) What thread does the JBBH35 bolt take, and will a standard 1/2 inch nut fit it?
It is 1/2-13, meaning a 1/2 inch diameter with 13 threads per inch, cut to ANSI/ASME B1.1. That is standard UNC coarse thread, so any 1/2-13 nut threads on. For dissimilar metal corrosion reasons, pair it with a silicon bronze nut and washer rather than plain steel.
3) Can I use silicon bronze hex bolts on a federally funded or Buy American job?
No. The JBBH35 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic-content clause, this bolt will not satisfy it.
4) What wrench or socket size does the 1/2-13 Metallics hex bolt need?
The hex head measures 0.736 to 0.750 inches across the flats, so a 3/4 inch wrench or socket is the one you want. Head height runs 0.302 to 0.323 inches.
5) How many bolts come in the Metallics JBBH35 jar?
Fifty bolts, packed in a jar, and 50 each is the order minimum. The jar pack is the J prefix in the part number; the same bolt is catalogued in the BBH and JBBH series in other lengths and pack quantities.
6) Do these silicon bronze hex bolts meet a dimensional spec I can put on a submittal?
Three standards are called out: ASME B18.2.1 for head and body dimensions, ANSI/ASME B1.1 for the 1/2-13 thread, and ASTM F468 for the silicon bronze material. That covers geometry, thread fit, and alloy on a submittal sheet.
7) What are silicon bronze hex bolts actually used for versus a galvanized steel bolt?
Metallics lists these for the electrical, plumbing, heating and air conditioning trades. Silicon bronze is the choice where corrosion or conductivity matters: ground rod and grounding connector hardware, buried and direct-earth-contact connections, marine and wet locations, and anywhere a galvanized bolt would sacrifice its coating and seize. For dry interior structural attachment, a plain or zinc plated steel hex bolt does the same mechanical job for less.
8) How much does a jar of 50 Metallics 1/2-13 x 3 bronze bolts weigh?
The packed jar weighs 9.64 lbs. Worth knowing if you are carrying several sizes up a ladder or figuring a shelf load in the truck.
