Metallics JBRHC35 Bolts 1/2-13 x 3 HXBT Br (Jar 50)

Solid brass. The material is listed as brass and the head color as brass, not a plating over steel. That matters for grounding and bonding work, where the bolt itself is part of the conductive path, and for outdoor or damp locations where a plated steel bolt would eventually rust through the coating.

No. The jar holds 50 brass hex bolts only, 1/2-13 by 3 inch. Order brass hex nuts and flat washers in 1/2 inch separately so the hardware stack stays all brass, mixing in zinc-plated steel nuts defeats the reason for buying brass in the first place.

Head width across the flats measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the right tool. Brass is softer than steel, so use a six-point socket rather than an open-end wrench if you are pulling any real torque, to avoid rounding the corners.

Brass is the common choice for grounding and bonding connections, ground bars, bus work, and water or gas pipe bonding clamps, because it conducts and because it does not set up the galvanic problem you get mixing zinc-plated steel against copper. These are catalogued by Metallics as electrical fasteners for exactly that work. Where you need high tensile strength in a structural connection, a brass bolt is the wrong pick, use a graded steel bolt instead.

Fifty bolts per jar, and 50 count is the order minimum, so one jar is the smallest buy. The jar is a sensible stocking pack for a van or a shop drawer since brass hex bolts in this size get used a few at a time rather than by the box.

Country of origin on the JBRHC35 is China. If a project has domestic-sourcing language in the specification, confirm the origin requirement against the submittal before releasing the order.

Yes. Metallics offers other sizes and quantities in the JBRHC brass hex bolt line by request, so if you need a shorter bolt for a thin bonding lug or a bulk count for a repeating install, that can be sourced rather than buying multiple jars of the 3 inch.
