Metallics JBBH26 – Frequently Asked Questions
1) Is the Metallics JBBH26 hex bolt silicon bronze all the way through, or just bronze plated?
Solid silicon bronze, not a plated steel bolt. The material is silicon bronze with a bronze finish, made to ASTM F468 for nonferrous bolting material. That is why it gets specified for marine, wet, and corrosive locations where a zinc plated steel bolt would rust out, and it is also why it is nonmagnetic.
2) What thread does the JBBH26 bolt take, and will a standard 3/8 nut fit it?
The thread is 3/8-16 UNC, cut to ANSI/ASME B1.1 at 16 threads per inch, so any standard 3/8-16 coarse nut threads on. For corrosion matching, pair it with a silicon bronze nut and washer rather than plated steel, otherwise you set up dissimilar metal contact at the joint.
3) Can I use the Metallics JBBH26 on a federally funded job with Buy American requirements?
No. The JBBH26 bronze hex bolt is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, this part will not satisfy it and you need a domestically produced silicon bronze bolt instead.
4) How thick a material can I clamp with a 3 inch long bolt like the JBBH26?
Shank length is 3 inches measured from under the hex head, so your total grip is 3 inches minus the nut and any washers you stack. Allow a thread or two of stickout past the nut. For thicker build-ups you need a longer bolt; Metallics offers other lengths in the BBH and JBBH series by request.
5) How many bolts come in a jar of JBBH26, and is there an order minimum?
They ship in a jar of 50, and 50 each is the order minimum. The packed jar weighs 5.08 lbs. The jar pack is what the J prefix on JBBH26 indicates; the same bolt in the BBH series is the bulk packaging.
6) What are silicon bronze hex bolts actually used for in electrical work?
They are the bolting of choice for grounding and bonding connections and for exterior or damp-location supports, because bronze stays conductive and does not corrode at the joint the way plated steel does. Metallics lists this bolt for the electrical, plumbing, heating and air conditioning trades. Typical jobs: ground bus and ground rod clamps, bonding straps, pool and fountain bonding, and strut or hanger connections in wet areas.
7) Is a bronze bolt the right pick over stainless for an outdoor grounding connection?
Both resist corrosion, but they are not interchangeable at a connection. Silicon bronze, which is what the JBBH26 is made from, is the usual match when the hardware it bolts to is bronze or copper, such as ground bars, clamps, and copper lugs, because like metals avoid galvanic action. Stainless is the choice for structural fastening into steel. If your connector body is copper or bronze, go bronze.
