Metallics BBH74 – Frequently Asked Questions
1) What thread does the Metallics BBH74 bolt take, and will a standard 5/8 inch nut fit it?
It is a 5/8-11 bolt, meaning 5/8 inch diameter with 11 threads per inch, which is standard UNC coarse thread cut to ANSI/ASME B1.1. Any standard 5/8-11 UNC nut will thread on. For grounding work, pair it with a silicon bronze nut rather than steel so you do not create a dissimilar metal joint.
2) Does the Metallics BBH74 silicon bronze bolt meet Buy American requirements for a federal job?
No. The BBH74 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries a domestic sourcing clause, this bolt will not satisfy it.
3) How does the Metallics BBH74 bolt come packaged, and is there a minimum order?
The BBH74 ships in a jar of 50 bolts, and 50 each is the order minimum. If you need a different size or a different count for a job, Metallics offers other sizes and quantities by request.
4) What material standard does the Metallics BBH74 bolt conform to?
Material conforms to ASTM F468, the standard covering nonferrous bolts and studs for general use, with silicon bronze as the alloy. Threads follow ANSI/ASME B1.1 and head dimensions follow ASME B18.2.1. That combination is what a spec writer is usually looking for when a drawing calls out a bronze bolt rather than plated steel.
5) Can I use a galvanized or zinc plated steel bolt instead of the silicon bronze BBH74?
Not where the bolt is in contact with copper or buried. The BBH74 is specified in silicon bronze precisely to avoid the galvanic corrosion you get when plated steel sits against copper grounding conductors or in damp soil. Substitute a steel bolt only in dry, non-grounding structural use where the spec does not call for a nonferrous fastener to ASTM F468.
6) How much usable grip length does a 3-1/4 inch long 5/8-11 bronze bolt give me?
The BBH74 measures 3-1/4 inches of bolt length under the head, so the clamped material plus the nut and any washers all have to fit inside that 3-1/4 inches. On a grounding plate or clamp stack-up, measure your total thickness and leave at least a nut's worth of thread engagement. The head itself adds roughly 0.378 to 0.403 inches of height above the surface.
