Metallics JBBH34 – Frequently Asked Questions
1) What thread does the Metallics JBBH34 silicon bronze hex bolt take, and will a standard 1/2 inch nut fit it?
The JBBH34 is a 1/2-13 hex bolt, 13 threads per inch, which is standard 1/2 inch UNC coarse thread made to ANSI/ASME B1.1. Any standard 1/2-13 coarse nut threads on. For a bronze installation, pair it with a silicon bronze nut and washer so you aren't mixing metals at the joint.
2) Why use a silicon bronze bolt instead of galvanized or stainless steel?
Silicon bronze is the choice where corrosion and galvanic compatibility drive the spec: marine and coastal work, water-contact assemblies, grounding and bonding hardware, and anywhere you are fastening to bronze or copper components and don't want a dissimilar-metal reaction. The JBBH34 is solid silicon bronze to ASTM F468 (the standard for nonferrous bolts), not a plated steel bolt, so the corrosion resistance goes all the way through rather than sitting in a coating that can be scraped during install.
3) Is the Metallics JBBH34 bolt Buy American or ARRA compliant for a government job?
No. The JBBH34 silicon bronze hex bolt is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-content clause, this part won't satisfy it and you'll need a bolt certified to that requirement.
4) How many bolts come in a jar of Metallics JBBH34, and can I buy fewer?
The JBBH34 ships as a jar of 50 bolts, and 50 each is the order minimum, so the jar is the smallest unit. Metallics lists other sizes and quantities in the BBH and JBBH series by request if 1/2-13 x 2-1/2 or a 50-count isn't what the job needs.
5) What trades actually use these silicon bronze hex bolts?
Metallics lists the BBH and JBBH hex bolts for the electrical, plumbing, heating and air conditioning industries. In practice that means grounding and bonding connections, hanger and support hardware in wet or corrosive areas, and fastening into bronze or copper plumbing components where a steel bolt would corrode at the joint.
6) Will the JBBH34 bolt match existing bronze hardware in appearance?
Finish is bronze, and it is the natural color of the silicon bronze itself rather than a plating or coating, so it blends with bronze and copper hardware. Like all bare bronze, it will darken and patina with exposure over time.
7) How much does a jar of 50 Metallics JBBH34 bronze bolts weigh for shipping?
A jar of 50 comes in at 8.38 lbs, with jar dimensions of 7.25 by 4.5 by 4.5 inches. Bronze is dense, so if you are ordering several jars for a large run, plan the weight into the delivery.
