Metallics JBBH80 Bolts 5/8-11 x 1 HXBT Sbr (Jar 100)

The JBBH80 is a 5/8-11 hex bolt, 11 threads per inch, cut to ANSI/ASME B1.1. That is standard UNC coarse thread for 5/8 inch diameter, so any 5/8-11 nut or tapped 5/8-11 hole mates with it. The head and body follow ASME B18.2.1 dimensions, so it drives with a standard 5/8 inch hex bolt wrench size.

Silicon bronze is the material of choice where corrosion and galvanic compatibility matter more than raw strength, typically marine, water-contact, and bronze-to-bronze connections. The JBBH80 is silicon bronze to ASTM F468, the standard that covers nonferrous bolting, and carries a bronze finish. Bolting bronze hardware with galvanized or stainless steel puts dissimilar metals in contact and invites galvanic corrosion; matching bronze to bronze avoids it. If you need high tensile capacity on a structural steel connection, a steel grade bolt is the correct part instead.

Grip length is short: the JBBH80 is a 1 inch long bolt under a hex head that measures 0.378 to 0.403 inch in height. With a nut and washer taken into account, it suits thin assemblies, bus bar, strap, and lug connections rather than thick stacked members. If you are through-bolting anything deeper than about half an inch of material, order a longer length.

No. The JBBH80 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. On federally funded work carrying domestic sourcing language, this bolt will not satisfy it, so specify a domestically produced silicon bronze fastener instead.

They ship in a jar of 100 bolts, and the jar is the minimum order unit, so 100 pieces is the smallest quantity. The packed jar weighs 16.37 lbs and measures 4.5 x 7.25 x 4.5 inches, useful if you are stocking a shelf or a service van bin. Other sizes and quantities are available by request.

Electrical, plumbing, and HVAC work is the stated application. In practice that means grounding and bonding connections, water-service and pump hardware, and any outdoor or damp-location assembly where a plated steel bolt would rust out. Nothing about the bolt restricts it to one trade, but it is stocked as an electrical-department fastener.

Within the BBH and JBBH series the JBBH part numbers are the jar-packed versions, and model JBBH80 is the 5/8-11 x 1 inch silicon bronze hex bolt in a jar of 100. If you need the same bolt in a different diameter, length, or quantity, other sizes and quantities within the series are available by request.
