Metallics JBBH77 – Frequently Asked Questions
1) What thread size and length is the Metallics JBBH77 hex bolt?
The JBBH77 is a 3/4-10 x 2 inch hex bolt: 3/4 inch diameter, 10 threads per inch (coarse), 2 inch length under the head. Threads follow ANSI/ASME B1.1, so it mates with any standard 3/4-10 nut or tapped hole. Head and body dimensions follow ASME B18.2.1.
2) Is the JBBH77 bolt silicon bronze or just bronze plated?
Solid silicon bronze, not a plated steel bolt. The material is silicon bronze to ASTM F468, which is the spec for nonferrous bolting, and the finish reads bronze because that is the base metal. That matters if you are fastening in a corrosive or wet environment where a plated bolt would eventually rust through the coating.
3) Is this bolt Buy American or ARRA compliant for a government job?
No. The JBBH77 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing requirement, this bolt will not satisfy it.
4) Why would I use a silicon bronze bolt instead of a galvanized or stainless one?
Silicon bronze is the choice where corrosion resistance and nonmagnetic, non-sparking behavior matter, and where dissimilar-metal contact with copper or bronze components would cause galvanic trouble. The JBBH77 is a 3/4-10 x 2 bolt in silicon bronze per ASTM F468, aimed at electrical, plumbing, heating and air conditioning work. For dry structural steel connections, a plain or galvanized steel bolt is the usual pick instead.
5) How many bolts come in a jar of Metallics JBBH77?
50 bolts per jar, and 50 each is also the order minimum, so one jar is the smallest buy. The packed jar weighs 19.88 lbs.
6) Do nuts and washers come with the JBBH77 bolts?
The jar contains the 3/4-10 x 2 hex bolts only. You will need to order matching 3/4-10 nuts and washers separately, and for a nonferrous assembly those should be silicon bronze as well so you do not set up a galvanic couple at the joint.
7) Will a 2 inch long 3/4 bolt be long enough for my connection?
The 2 inch figure is the shank length under the head, so your total grip (material thickness plus washers plus nut height) has to fit inside that. On a 3/4-10 bolt a heavy hex nut alone eats roughly half an inch of it, so 2 inches suits thinner clamped assemblies. Metallics makes the BBH and JBBH series in other lengths and pack quantities on request if you need more grip.
8) What size wrench or socket does the JBBH77 hex bolt head take?
It is a standard hex head built to ASME B18.2.1, so a 3/4 inch diameter bolt takes a 1-1/8 inch wrench across the flats on a finished hex pattern. Plan tool clearance around that before you commit to the layout.
