Metallics JBBH76 – Frequently Asked Questions
1) What size and thread is the Metallics JBBH76 hex bolt?
The JBBH76 is a 5/8-11 hex bolt, 4 inches long, with 11 threads per inch cut to ANSI/ASME B1.1. The hex head measures 0.922 to 0.938 inch across the flats, so a 15/16 inch wrench or socket fits it. Head height runs 0.378 to 0.403 inch.
2) Is the JBBH76 bolt stainless or bronze, and will it hold up outdoors or in a wet location?
Silicon bronze, with a bronze finish, made to ASTM F468 for nonferrous bolting material. Silicon bronze is the usual choice where corrosion and galvanic compatibility with bronze or copper hardware matter, which is why it shows up in marine, water and grounding work rather than plain zinc-plated steel.
3) Will a standard 5/8 inch bronze nut and a standard clearance hole work with this bolt?
Yes. The JBBH76 is dimensioned to ASME B18.2.1 and threaded to ANSI/ASME B1.1, so it is a standard 5/8-11 UNC hex bolt in head size, thread pitch and body diameter. Any standard 5/8-11 nut threads on, and a 11/16 inch clearance hole is the normal fit for a 5/8 bolt.
4) Is the Metallics JBBH76 bolt Buy American or ARRA compliant for a government job?
No. The JBBH76 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 part will not satisfy it.
5) How many bolts come in a jar of Metallics JBBH76?
Fifty bolts per jar, and 50 each is the order minimum, so the jar is the base buying unit. The packed jar weighs 15.35 lbs.
6) Do nuts and washers come with the JBBH76 bolts, or do I order those separately?
The jar is bolts only, 50 hex bolts in 5/8-11 x 4. Nuts and washers are separate line items, and for silicon bronze bolting you want matching silicon bronze nuts and washers so you are not mixing metals at the joint.
7) I need 5/8-11 silicon bronze bolts in a length other than 4 inches. Can I get them?
Yes. The BBH and JBBH line runs other lengths and other pack quantities beyond the 4 inch jar of 50 under part number JBBH76, available by request. Give the diameter, thread, and length you need and the quantity.
8) What trades use these silicon bronze hex bolts?
Metallics lists the BBH and JBBH bolts for the electrical, plumbing, and heating and air conditioning trades. Typical uses are bonding and grounding connections, bronze valve and flange work, and any assembly where a bronze or copper mating part rules out plated steel fasteners.
