Metallics JBBH24 – Frequently Asked Questions
1) Is the Metallics JBBH24 hex bolt silicon bronze all the way through, or just bronze plated?
Solid silicon bronze, not a plating. The material is silicon bronze to ASTM F468, and the bronze appearance is the base metal itself. That is why it gets used in wet and grounding work where a plated steel bolt would corrode once the coating is scratched.
2) What thread does the JBBH24 bolt use, and will a standard 3/8 nut fit it?
The JBBH24 is a 3/8 inch diameter bolt with 16 threads per inch, cut to ANSI/ASME B1.1. 3/8-16 is standard UNC coarse thread, so any off-the-shelf 3/8-16 nut or tapped 3/8-16 hole mates with it. For galvanic reasons, pair it with a silicon bronze or bronze nut rather than plain steel when it is going into a damp location.
3) Can I use silicon bronze hex bolts on a federal or Buy American job?
No. The JBBH24 is listed as not Buy American compliant and not ARRA compliant, with country of origin recorded as multiple. If your contract carries a domestic sourcing clause, you will need a domestically produced fastener instead.
4) How long is the JBBH24 bolt and how much grip does the head take up?
Length is 2 inches. The hex head measures 0.551 to 0.562 inch across the width and 0.226 to 0.243 inch in head height, which is standard 3/8 inch hex geometry per ASME B18.2.1, so a 9/16 inch wrench or socket drives it.
5) How many bolts come in a jar of Metallics JBBH24, and can I buy fewer?
They ship as a jar of 100 pieces, and the jar is the order minimum, so 100 is the smallest buy on this item. Total weight of the jar is 7.29 lbs. Other sizes and quantities in the BBH and JBBH hex bolt series are available by request.
6) I need the same bolt in a different length or diameter for the rest of the run. What are my options?
The JBBH24 is one size in Metallics' BBH and JBBH silicon bronze hex bolt series, at 3/8-16 x 2 inch. Other diameters, lengths and pack quantities in that series can be requested, so you can keep the same silicon bronze material and ASTM F468 spec across a mixed-length installation.
7) What trades actually use a silicon bronze hex bolt like this?
It is sold for electrical, plumbing, heating and air conditioning work. Typical uses are grounding and bonding connections, outdoor and marine-exposed equipment mounting, and any assembly where dissimilar-metal corrosion or rust staining from a plated steel bolt would be a problem.
