Metallics JBBH13 – Frequently Asked Questions
1) Is the Metallics JBBH13 hex bolt actually solid silicon bronze or just bronze plated?
Solid silicon bronze, not a plated steel bolt. The material is silicon bronze throughout with a bronze finish, and it is made to ASTM F468, the standard covering nonferrous bolts and studs. That matters for grounding and marine or damp-location work where a plated steel bolt would corrode at the plating breaks.
2) What thread does the JBBH13 bolt use, and will a standard 5/16-18 nut fit it?
It is a 5/16-18 bolt, 18 threads per inch, cut to ANSI/ASME B1.1, so any standard 5/16-18 UNC nut or tapped hole will take it. For a full bronze connection, pair it with a silicon bronze nut rather than a zinc-plated steel one, since mixing metals at a wet connection is what starts galvanic corrosion.
3) Does the Metallics JBBH13 bolt meet Buy American or ARRA requirements for a public project?
No. It is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. On federally funded or state domestic-preference work that specifies domestic fasteners, this one will not satisfy the submittal.
4) What size wrench or socket does this 5/16-18 hex bolt need?
The hex head measures 0.489 to 0.500 inch across the flats, so a 1/2 inch wrench or socket is the right fit. Head height runs 0.195 to 0.211 inch. The head is a standard hex, dimensioned to ASME B18.2.1, so it drives like any other inch-series hex bolt.
5) How is the JBBH13 packaged, and can I buy fewer than a jar?
It ships as a jar of 100 bolts, and the jar is the order minimum, so 100 pieces is the smallest quantity. Jar packaging is handy on a service truck because the bolts stay together instead of loose in a bin. Other sizes and quantities are available by request.
6) Are silicon bronze hex bolts the right choice for outdoor or wet electrical connections?
That is exactly where they earn their keep. Silicon bronze resists corrosion without relying on a coating, so it holds up on grounding connections, outdoor boxes, water-adjacent plumbing and mechanical work. Metallics lists this bolt for electrical, plumbing, heating and air conditioning use. If the connection is dry interior and nothing is bonded to copper, a plated steel hex bolt does the same mechanical job for less metal cost.
7) How much does a jar of 100 of these 5/16 bronze bolts weigh for shipping?
A jar comes in at 5.71 lbs. The container itself is 5.75 in high and 3.5 in on each side, so it stacks neatly in a van bin or a parts drawer.
8) I need a longer bronze hex bolt in the same 5/16-18 thread. Is that available?
The JBBH13 is the 1-1/2 inch length in the BBH and JBBH silicon bronze hex bolt series. Other sizes and quantities within the series are available by request, so a longer 5/16-18 bronze bolt can be quoted rather than substituted with a different material.
