Metallics JBBH89 – Frequently Asked Questions
1) Why would I use a silicon bronze bolt instead of a galvanized steel one?
The JBBH89 is silicon bronze to ASTM F468, the standard for nonferrous bolting. Silicon bronze holds up in wet and corrosive service, in contact with copper or bronze components, and where you want to avoid galvanic mismatch against copper piping, bus, or grounding hardware. It is the usual pick for marine, water-contact, and underground electrical work where a plated steel bolt would rust out.
2) Are these Metallics bronze bolts Buy American or ARRA compliant for a government job?
No. The JBBH89 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic sourcing clause, this bolt will not satisfy it.
3) Do nuts and washers come with the Metallics JBBH89 bolts?
No. The JBBH89 jar is hex bolts only, 50 of them. Order 3/4-10 nuts and 3/4 inch washers separately, and in silicon bronze if you are buying this bolt for corrosion reasons, since pairing a bronze bolt with plated steel nuts reintroduces the galvanic problem you were avoiding.
4) What trades actually use the Metallics JBBH89 silicon bronze hex bolt?
It is sold into the electrical, plumbing, heating and air conditioning trades. Typical use is bolting bronze or copper hardware, ground plates and clamps, pipe supports, and equipment anchorage where corrosion resistance matters more than the tensile strength of a steel grade bolt.
5) How heavy is a jar of 50 Metallics JBBH89 bolts?
A jar runs 24.55 lbs, which matters if you are specifying shipping, hand-carrying to a roof, or stocking shelves. Jar footprint is 4.5 x 4.5 x 7.25 inches.
6) Is the bronze color on these bolts a finish or the actual metal?
It is the metal. The JBBH89 is solid silicon bronze and the bronze finish is the bare alloy, not a coating, so cut threads and wrench marks will not expose a dissimilar base metal the way a plated steel bolt does.
