Metallics JBBH73 – Frequently Asked Questions
1) What size and thread is the Metallics JBBH73 hex bolt?
It's a 5/8-11 x 3 inch hex bolt: 5/8 inch diameter, 11 threads per inch (coarse UNC), 3 inches of length under the head. Threads are cut to ANSI/ASME B1.1, so it mates with any standard 5/8-11 nut or tapped hole.
2) Is the JBBH73 bolt stainless or something else? What is it made of?
Silicon bronze, not stainless or plated steel, with a bronze finish and material conforming to ASTM F468. Silicon bronze is what gets specified where corrosion and galvanic compatibility with bronze or copper hardware matter, such as marine, water, and grounding work.
3) Can I use these silicon bronze bolts on a Buy American or ARRA-funded job?
No. The JBBH73 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If the project carries a domestic sourcing requirement, this bolt will not satisfy it.
4) How is the JBBH73 sold, loose or by the box?
It ships in a jar of 100 bolts, and 100 (one jar) is the minimum order. There is no loose-piece count on this item. Metallics does make other sizes and quantities in the BBH and JBBH series available by request.
5) What trades actually use a bronze hex bolt like this instead of a plain steel one?
Metallics lists this bolt for electrical, plumbing, heating and air conditioning work. Electricians reach for silicon bronze on grounding and bonding connections and in damp or buried locations; plumbers and mechanical contractors use it where the bolt contacts copper or bronze and a steel fastener would corrode out.
6) Do nuts and washers come with the JBBH73 bolts?
No. The jar of 100 contains hex bolts only, no nuts or washers. Order 5/8-11 nuts separately, and in silicon bronze if you want to keep the whole connection in matching material and avoid mixing metals.
7) How much does a jar of 100 of these 5/8 x 3 bronze bolts weigh for shipping?
A full jar of 100 comes in at 28.71 lbs. The packed jar measures 7.25 in by 4.5 in by 4.5 in. Worth planning for if you are ordering several jars to a jobsite by hand truck.
