Metallics JBBH4 – Frequently Asked Questions
1) What size and thread is the Metallics JBBH4 hex bolt?
It's a 1/4-20 bolt, 2 inches long, with 20 threads per inch cut to ANSI/ASME B1.1. The hex head measures 0.428 to 0.438 inch across the flats and 0.150 to 0.163 inch high, so a 7/16 inch wrench or socket fits it. Dimensions follow ASME B18.2.1.
2) Is the JBBH4 bolt silicon bronze all the way through, or just a bronze coating?
Solid silicon bronze, not plated. The material is specified to ASTM F468, the standard covering nonferrous bolts and studs, and the finish is bronze because that is the base metal. That is why it gets specified for grounding and for wet or corrosive locations where a plated steel bolt would rust out.
3) Are Metallics JBBH4 bolts Buy American or ARRA compliant for a federal or municipal job?
No. The JBBH4 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your spec carries a domestic-sourcing requirement, this bolt will not satisfy it.
4) How many bolts come in a jar of Metallics JBBH4, and can I buy fewer?
They ship in a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest quantity. Metallics does offer other sizes and quantities by request if you need a different count or length.
5) Do I need special nuts and washers with silicon bronze bolts, or will standard steel ones do?
Pair them with silicon bronze or at least bronze/brass nuts and washers. Mixing zinc-plated steel nuts onto a silicon bronze bolt in a wet location puts two dissimilar metals in contact and the steel corrodes first, which defeats the reason you bought bronze. The JBBH4 is a 1/4-20 thread to ANSI/ASME B1.1, so any standard 1/4-20 nut threads on, the question is only metal choice. Nuts and washers are not included in the jar of 100 bolts.
6) How much does a jar of 100 of the 1/4-20 x 2 inch silicon bronze hex bolts weigh?
3.16 lbs for the jar. The packaged jar measures 5.75 inches in one dimension and 3.5 by 3.5 inches in the others, so it fits a standard service van parts bin.
7) What is the difference between the Metallics BBH and JBBH bolt part numbers?
Both belong to the same silicon bronze hex bolt family, the BBH and JBBH series. The J prefix identifies the jar-packed version, which is how JBBH4 ships: 100 pieces in a jar rather than loose bulk.
