Metallics JBRHC34 – Frequently Asked Questions
1) What thread size are the Metallics JBRHC34 brass hex bolts, and will they take a standard 1/2-13 nut?
Thread is 1/2-13, 13 threads per inch, which is standard UNC coarse for a 1/2 inch bolt. Any standard 1/2-13 nut or tapped 1/2-13 hole will take it. Measured shank diameter runs 0.4930 to 0.5000 inch, so it drops through a nominal 1/2 inch hole only if the hole is clearance drilled (9/16 inch or larger is typical).
2) Are these bolts solid brass or just brass plated?
Solid brass. Both the material and the head color are listed as brass, not a plating over steel. That matters on two counts: brass will not rust in damp or outdoor grounding work, and it is softer than a steel grade bolt, so torque it by feel rather than to a steel spec and avoid using it where high clamp load is the point.
3) How many bolts come in a jar, and can I buy fewer than 50?
They ship 50 to a jar, and 50 counts is the order minimum, so the jar is the smallest purchasable unit. Other sizes and quantities can be had by request if 1/2-13 x 2-1/2 is not the length you need.
4) What wrench or socket size fits the head on these 1/2-13 brass hex bolts?
Head width across the flats is 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the fit. Wrenching height on the head is 0.215 inch, which is the usable bearing depth your socket has to grip, so a deep socket with a full-depth bore seats better than a thin-wall adapter.
5) Why would an electrician use a brass hex bolt instead of a galvanized steel one?
Brass is the usual choice on grounding and bonding connections and on busbar or lug hardware, because it is conductive and corrosion resistant, and it avoids the galvanic pairing you get putting steel against copper. The JBRHC34 is catalogued on the electrical side for exactly that kind of work. For structural anchoring or anywhere the joint carries load, use a steel grade bolt instead.
6) Do the Metallics JBRHC34 bolts meet Buy American and ARRA requirements on a government job?
Both compliance flags are marked compliant on the JBRHC34 record, ARRA and Buy American. Country of origin is listed as China, so if your contract is written to a domestic-melt or domestic-manufacture clause rather than the ARRA/BAA designation, confirm which standard your spec actually invokes before you submit it.
7) I need to order replacements for brass hardware already installed. What do I give purchasing?
Order by Metallics part number JBRHC34, described as a 1/2-13 x 2-1/2 brass hex bolt, jar of 50. It is the JBRHC series. One model covers this size, so there is no finish or grade option to specify alongside it.
