Metallics JBBH47 – Frequently Asked Questions
1) Is the Metallics JBBH47 hex bolt actually silicon bronze, or just bronze plated?
Solid silicon bronze, not a plating. The JBBH47 is made of silicon bronze to ASTM F468, the standard covering nonferrous bolts and studs, with a bronze finish that is the base metal itself. That is why it holds up in wet, marine, and corrosive grounding work where a plated steel bolt would eventually rust through.
2) What thread does the Metallics JBBH47 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 standard 1/2-13 nut threads on. For full corrosion protection on the assembly, pair it with a silicon bronze nut and washer rather than plated steel, or you reintroduce dissimilar metal at the joint.
3) Does the Metallics JBBH47 bolt meet Buy American or ARRA requirements for a public project?
No. The JBBH47 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your job carries a domestic-content clause, this bolt will not satisfy it and you need a domestically sourced silicon bronze fastener instead.
4) What wrench size fits the head of the Metallics JBBH47 hex bolt?
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. Those dimensions follow ASME B18.2.1, so it drops into any standard hex bolt clearance or counterbore detail.
5) How many bolts come in a jar of Metallics JBBH47, and can I buy just a few?
The JBBH47 ships as a jar of 50, and 50 each is the order minimum, so it is a full-jar purchase rather than a loose count. Metallics does offer other sizes and quantities on request within the BBH and JBBH hex bolt series.
6) What is a silicon bronze hex bolt used for on an electrical job?
Silicon bronze hex bolts like the JBBH47 are specified for electrical, plumbing, heating and air conditioning work, typically where a fastener has to stay conductive and corrosion resistant. Common uses are ground rod and grounding strap connections, bonding hardware, and any buried or damp-location joint where zinc plated steel would corrode and lose contact. Bronze also avoids galvanic trouble when you are bolting to copper.
7) Will the JBBH47 hex bolt match the grip length I need?
The JBBH47 is the 1/2-13 by 1-1/2 inch length in the Metallics BBH and JBBH hex bolt line. Measure from under the head: 1-1/2 inches has to cover your combined material thickness plus a nut and washer, so figure roughly an inch of usable grip. If your stack is thicker, Metallics offers other lengths in the same series on request.
8) How much does a jar of 50 Metallics JBBH47 bolts weigh for shipping?
The packed jar weighs 5.87 lbs and measures 3.5 in by 3.5 in by 5.75 in. Useful if you are consolidating a van stock order or figuring freight on a multi-jar pull.
