Metallics JBBH22 – Frequently Asked Questions
1) Why use a silicon bronze bolt instead of galvanized or stainless steel?
Silicon bronze is the material here, made to ASTM F468 (bolts and studs of nonferrous alloys). It is chosen for corrosion resistance in wet, marine, and grounding work, and for bolted connections where you want to avoid galvanic reaction against bronze or copper parts. Against galvanized steel it holds up better in salt and chemical exposure; against stainless it keeps compatibility with copper and bronze hardware.
2) Will a standard 1/2 inch wrench or socket fit the head on this bolt?
Yes. The hex head measures 0.736 to 0.750 inch across the flats, which is the standard 3/4 inch wrench size for a 1/2 inch bolt, and head height runs 0.302 to 0.323 inch. The bolt is dimensioned to ASME B18.2.1, so it drops into any fixture or socket set built around standard square and hex bolt dimensions.
3) How many bolts come in a jar of Metallics JBBH22, and can I buy fewer than a full jar?
The JBBH22 ships as a jar of 50 bolts, and 50 count is the order minimum, so the jar is the smallest unit sold. Metallics also offers other sizes and quantities in this hex bolt line by request if 1/2-13 x 2-3/4 in a 50 jar is not the pack you need.
4) Does the Metallics JBBH22 bolt meet Buy American and ARRA requirements on a federal job?
The JBBH22 is flagged compliant for both Buy American and ARRA, with country of origin listed as China. On a federally funded project, bring both of those facts to the specifying authority, since compliance determinations turn on the program and the waiver in place for the contract.
5) Is the JBBH22 a full hex bolt or a hex cap screw, and does it come with a nut?
It is a hex head bolt, type listed as hexagonal bolt, dimensioned to ASME B18.2.1. The jar contains bolts only, so order 1/2-13 silicon bronze nuts and any flat or lock washers separately if the joint needs them.
6) What does a jar of these 1/2-13 x 2-3/4 silicon bronze bolts weigh for shipping and tool-crib handling?
A full jar comes in at 9.27 lbs, and the jar itself is 4.5 inches wide by 4.5 inches long and 7.25 inches high. That matters if you are stocking several on a van shelf or a service truck bin.
7) What finish are Metallics silicon bronze hex bolts, and will they match bronze ground clamps and copper connectors?
Finish is bronze, which is the natural color of the silicon bronze alloy rather than a plating, so there is no coating to chip or wear through at the wrench flats. It visually and electrochemically suits bronze grounding hardware and copper conductors, which is the usual reason this bolt gets specified on electrical work.
