Metallics JBRHC67 Bolts 1/2-13 x 2-3/4 HXBT Br (Jar 50)

It's a 1/2-13 bolt: 1/2 inch nominal diameter with 13 threads per inch, which is standard UNC coarse thread. Measured shank outside diameter runs 0.4930 to 0.5000 inch, so it threads into any 1/2-13 tapped hole, nut, or coarse-thread insert. Length is 2-3/4 inches.

Metallics lists the JBRHC67 as both ARRA compliant and Buy American compliant. Country of origin is China. On a federally funded project, hand both of those facts to whoever is approving submittals, since the applicable clause on your contract decides which one governs.

The JBRHC67 is solid brass through the head and body, not plated steel. Brass is the usual choice where the bolt is part of a bonding or grounding path to copper or bronze hardware, because it stays conductive and doesn't set up the galvanic corrosion you get between zinc-plated steel and copper. If the bolt is purely structural and not carrying current or touching copper, a steel bolt is the cheaper answer.

Head width across flats measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the fit. That's the standard across-flats dimension for a 1/2 inch hex bolt, so existing 3/4 inch tooling on the truck works without adding a size.

They ship as a jar of 50 pieces, and 50 count is the order minimum, so it's sold by the full jar rather than loose. Other sizes and quantities are available by request.

No. The jar contains 50 brass hex bolts only, 1/2-13 x 2-3/4. Order matching 1/2-13 brass hex nuts and brass flat washers separately if the connection needs them, or thread into an existing 1/2-13 tapped hole.

Solid brass. Product material is listed as brass and the head color is brass as well, so there's no steel core under a finish to corrode once the surface is nicked during install.
