Metallics JBBH33 – Frequently Asked Questions
1) What thread does the Metallics JBBH33 hex bolt take, and will a standard 1/2 inch nut fit it?
The JBBH33 is a 1/2-13 bolt, 13 threads per inch, cut to ANSI/ASME B1.1. That is standard 1/2 inch UNC coarse thread, so any off-the-shelf 1/2-13 coarse nut or tapped 1/2-13 hole will take it. For a bronze installation, pair it with a silicon bronze nut so you are not mixing metals at the joint.
2) Why use a silicon bronze bolt instead of a galvanized or stainless hex bolt?
Silicon bronze is chosen where corrosion and galvanic compatibility matter more than raw strength, typically wet, marine, or buried work, and where the surrounding hardware is bronze or copper. The JBBH33 is silicon bronze with a bronze finish, made to ASTM F468 (the standard covering nonferrous bolts for general use). If you bolt into copper or bronze with galvanized steel, the steel corrodes first; bronze avoids that. If you only need strength in a dry interior setting, a plain or zinc-plated steel hex bolt is the cheaper call.
3) Will these silicon bronze bolts pass a Buy American or ARRA-funded job?
No. The JBBH33 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements, you need a domestically manufactured bolt instead.
4) What size wrench or socket do I need for this hex bolt head?
Head width across flats measures 0.736 to 0.750 in., which is a 3/4 inch wrench or socket. Head height runs 0.302 to 0.323 in. The head is a plain hex, dimensioned to ASME B18.2.1, so standard clearances and socket depths apply.
5) How many bolts come in a jar of Metallics JBBH33, and can I buy fewer?
It ships as a jar of 50 pieces, and 50 each is the order minimum, so a single jar is the smallest buy. Other sizes and quantities can be had by request if 2 inch or 1/2-13 is not what the job needs.
6) What trades actually use these bronze hex bolts on the job?
Metallics lists the JBBH33 for electrical, plumbing, heating and air conditioning work. In practice that is grounding and bonding connections, bronze pipe clamps and ground clamps, equipment supports in damp mechanical rooms, and anywhere a copper or bronze fitting is being bolted and a steel fastener would corrode at the joint.
7) How much does a jar of 50 of these 1/2-13 x 2 bronze bolts weigh for shipping?
The packed jar runs 7.17 lbs, measuring 4.5 x 4.5 x 7.25 inches. Worth knowing if you are stocking a van or a shelf, since bronze is heavier per piece than a comparable steel bolt.
