Metallics JBBH79 – Frequently Asked Questions
1) What size and thread is the Metallics JBBH79 hex bolt?
The JBBH79 is a 3/4-10 x 2-1/2 inch hex bolt, so 3/4 inch diameter with 10 threads per inch (coarse UNC) and 2-1/2 inches of length under the head. Threads are cut to ANSI/ASME B1.1, and the head and overall dimensions follow ASME B18.2.1, so it mates with any standard 3/4-10 nut or tapped hole and takes a standard 1-1/8 inch wrench.
2) Is this a silicon bronze bolt, and why would I use bronze instead of galvanized steel?
Silicon bronze is the material, made to ASTM F468 (the standard covering nonferrous bolts for general use). Electricians and utility crews specify it where corrosion and galvanic compatibility matter: grounding and bonding connections, bronze or copper hardware, marine and wet environments. Against a copper ground conductor or a bronze clamp, bronze avoids the galvanic mismatch you get with plated steel, and it will not rust out the joint over time. The finish is bronze throughout, not a coating.
3) Can I use the Metallics JBBH79 on a federally funded or Buy American job?
No. The JBBH79 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries Buy American or ARRA domestic-sourcing requirements, this bolt will not satisfy them and you need a domestically sourced silicon bronze fastener instead.
4) How many bolts come in a jar of Metallics JBBH79?
Fifty bolts per jar, and 50 each is the order minimum, so the jar is the buying unit. The jar pack is what the JBBH prefix denotes in the BBH and JBBH series. Packed jar weight is 20.18 lbs.
5) Does the JBBH79 come with nuts and washers?
No. The jar contains the 3/4-10 x 2-1/2 hex bolts only. Order matching 3/4-10 silicon bronze hex nuts and bronze washers separately if you need the full set, and keep them in the same material to avoid a dissimilar-metal joint.
6) What trades and applications is this bronze hex bolt intended for?
It is catalogued for the electrical, plumbing, heating and air conditioning industries. In practice that is grounding and bonding hardware, bronze pipe and valve bolting, hanger and support connections in damp mechanical rooms, and anywhere a maintenance crew wants a fastener that will come apart again years later without seizing.
7) Can I get this bronze hex bolt in a different length or a smaller quantity?
Yes, other sizes and quantities in the BBH and JBBH series are available by request. The BBH designation covers the bulk packaging and JBBH the 50-count jar, so the same 3/4-10 bolt can be had in other lengths and pack formats.
