Metallics JBBH87 – Frequently Asked Questions
1) What size and thread is the Metallics JBBH87 hex bolt?
The JBBH87 is a 3/4-10 x 3 inch hex bolt: 3/4 inch diameter, 10 threads per inch (coarse UNC), 3 inch length under the head. Threads are cut to ANSI/ASME B1.1 and the bolt body follows ASME B18.2.1 dimensional standard, so it mates with any standard 3/4-10 nut or tapped hole.
2) Is the JBBH87 bolt actually silicon bronze, or just bronze plated?
Solid silicon bronze, not a plated steel bolt. The material is silicon bronze to ASTM F468 and the finish is bronze, meaning the corrosion resistance goes all the way through. That matters for grounding work and wet or marine locations where a plated fastener would eventually rust through its coating.
3) Will Metallics JBBH87 bolts meet a Buy American requirement on a federal job?
No. The JBBH87 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project specification carries a domestic-sourcing clause, this bolt will not satisfy it.
4) Can I use a silicon bronze hex bolt for grounding and bonding connections?
That is one of its main uses. Silicon bronze hex bolts are specified where a copper-alloy fastener is wanted at a connection, and the JBBH87 is catalogued for electrical, plumbing, heating and air conditioning work. Being a copper alloy rather than plated steel, it avoids the galvanic mismatch you get bolting steel hardware to copper bus or copper ground plate.
5) How many bolts come in a jar of Metallics JBBH87?
Fifty bolts per jar, and 50 each is the order minimum. The jar pack is the reason for the JBBH prefix in the Metallics BBH and JBBH series, BBH being the loose-count version of the same bolt.
6) Do nuts or washers come with the JBBH87 bolts?
No. The jar of 50 is bolts only, model JBBH87. Order 3/4-10 nuts and 3/4 inch washers separately, and for a dissimilar-metal connection keep them in silicon bronze or another copper alloy to match the bolt rather than mixing in plated steel.
7) What is the usable grip on a 3 inch long 3/4-10 hex bolt?
Length is measured 3 inches from under the hex head to the tip, per ASME B18.2.1. So the combined thickness of what you are clamping has to be under 3 inches, and you need to leave room for a nut and washers. If your stack is thicker, step up to a longer length in the same BBH/JBBH silicon bronze series.
8) Do I need a different size or count of these silicon bronze hex bolts?
The JBBH87 covers 3/4-10 x 3 inch in a 50-count jar, and Metallics offers other diameters, lengths and pack quantities in the same BBH and JBBH silicon bronze hex bolt series by request.
