Metallics JBBH75 – Frequently Asked Questions
1) What size and thread is the Metallics JBBH75 hex bolt, and will it take a standard 5/8-11 nut?
The JBBH75 is a 5/8-11 x 3-1/2 inch hex bolt, so 11 threads per inch on a 5/8 inch diameter. Threads are cut to ANSI/ASME B1.1, which means any standard 5/8-11 UNC nut or tapped hole mates with it. Head geometry follows ASME B18.2.1, with a head width across flats of 0.922 to 0.938 inch, so a standard 15/16 inch wrench or socket fits.
2) Why would I use a silicon bronze bolt instead of a galvanized or stainless one?
Silicon bronze is the material here, made to ASTM F468 (the standard covering nonferrous bolts for general use). Trades reach for silicon bronze where corrosion and galvanic compatibility matter more than raw strength, typically wet or marine environments, and where the fastener has to sit against bronze or copper hardware without setting up a dissimilar-metal reaction. If you only need general dry-interior strength, a plain or galvanized steel hex bolt is the cheaper call.
3) Is the Metallics JBBH75 bolt Buy American or ARRA compliant for a government job?
No on both counts. The JBBH75 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries domestic-sourcing language, this bolt will not satisfy it and you need a domestically produced silicon bronze hex bolt instead.
4) How many bolts come in a jar of Metallics JBBH75?
Fifty bolts per jar. The jar is the pack type and 50 each is the order minimum, so a single buy gets you the full 50 count rather than loose pieces. Other sizes and quantities can be requested if 5/8-11 x 3-1/2 is not the length you need.
5) Do I get nuts and washers with the Metallics JBBH75, or do I order those separately?
The JBBH75 is bolts only, 50 hex bolts in a jar. Nuts and washers are not part of the pack, so order matching 5/8-11 hardware separately. For a corrosion-sensitive or bonding application, match the nut and washer material to the silicon bronze bolt rather than mixing in plated steel.
6) What trades actually use these silicon bronze hex bolts?
Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. In practice that is grounding and bonding connections, equipment and hanger mounting, and pipe or duct support work where a corrosion-resistant nonferrous bolt is specified in place of steel.
7) What finish is the JBBH75 bolt, and does it need plating or paint?
Bronze finish, which is the natural color of the silicon bronze the bolt is made from rather than a coating over steel. There is no plating to scratch through or touch up, and the corrosion resistance is in the base metal, so no field finishing is needed.
8) How much does a jar of 50 of these 5/8 bronze bolts weigh for shipping or carrying up to a roof?
A jar comes in at 32.26 pounds, with jar dimensions of 7.25 by 4.5 by 4.5 inches. That is a one-hand carry but a heavy one, worth knowing if you are staging several jars on a lift or a rooftop unit install.
