Metallics JBRHC104 – Frequently Asked Questions
1) What thread size and pitch are the Metallics JBRHC104 brass hex bolts?
They're 5/16-18, meaning a 5/16 inch nominal diameter with 18 threads per inch (standard UNC coarse thread). Measured shank outside diameter runs 0.3065 to 0.3125 inch, so they thread into any 5/16-18 tapped hole or nut.
2) Are these bolts solid brass or just brass plated?
Solid brass. Material is listed as brass and the head color as brass, not a plating over steel. That matters on grounding and bonding work and in damp or corrosive locations where a plated steel bolt would rust through.
3) Do these brass bolts meet Buy American and ARRA requirements on a federal or institutional job?
Both the ARRA and Buy American fields are flagged compliant for the JBRHC104, while country of origin is listed as China. If your specification is written to a domestic-melt-and-manufacture standard rather than to ARRA/Buy American as flagged here, confirm the exact clause language against your submittal before you order.
4) What wrench or socket size fits the hex head on the JBRHC104?
Head width across flats measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket is the fit. Head height is 13/64 inch, with a wrenching height of 0.14 inch, so there's limited bearing surface for a deep socket on a thin head.
5) How many brass hex bolts come in a jar of Metallics JBRHC104?
100 bolts per jar, and 100 count is the order minimum, so the jar is the smallest buying unit. The packed jar weighs 2132 g. Other sizes and quantities can be had by request.
6) Should I use a brass hex bolt or a plated steel one for electrical work?
Brass is the choice where you need corrosion resistance and a non-magnetic, conductive fastener, typical of grounding clamps, bonding straps, meter and panel hardware, and exterior or wet locations. Plated steel carries more load and costs less, so it stays in dry structural and strut work. The JBRHC104 is solid brass through the head and shank.
7) Does the JBRHC104 jar include nuts or washers?
No. The jar is 100 brass hex bolts only, 5/16-18 x 1-3/4. Order matching 5/16-18 brass hex nuts and brass flat washers separately if the assembly needs an all-brass stack to avoid dissimilar-metal contact.
