Metallics JBRHC43 – Frequently Asked Questions
1) What thread size and length is the Metallics JBRHC43 brass hex bolt?
The JBRHC43 is a 5/16-18 hex bolt, 1 inch long. The 18 threads per inch is the standard UNC coarse pitch for 5/16 diameter, so it mates with any 5/16-18 nut or tapped hole. Measured shank outside diameter runs 0.3065 to 0.3125 inch.
2) Is the JBRHC43 bolt solid brass or just brass plated?
Solid brass. Both the material and the head color on the JBRHC43 are listed as brass, which is why it gets specified for grounding and bonding work and for wet or corrosive locations where a plated steel bolt would rust out.
3) What wrench or socket size fits the 5/16-18 brass hex bolt head?
Across the flats the head measures 0.489 to 0.500 inch, so a 1/2 inch wrench or socket fits it. Head height is 13/64 inch, with 0.14 inch of wrenching height, so keep tool engagement in mind in tight boxes or enclosures.
4) How many bolts come in a jar of Metallics JBRHC43?
They ship 100 to a jar, and 100 count is the order minimum. The jar packaging suits a van stock or a shop drawer where loose brass hardware otherwise gets lost. Each jar weighs 1379 g.
5) Will a brass hex bolt satisfy Buy American requirements on a federal job?
The JBRHC43 is flagged compliant for both ARRA and Buy American in the product record, while country of origin is listed as China. On a federally funded project, submit those two flags with the origin statement and let the specifying authority confirm against the contract clause in force.
6) Is a 1 inch long bolt long enough to bond a ground conductor to a steel enclosure?
One inch of overall length gives usable thread for a single sheet of enclosure steel plus a lug and nut, but it is short for stacked lugs, thick bus, or anything with a spacer behind it. Add up your material thickness, the lug, and the nut height first. Other lengths in the same 5/16-18 brass hex pattern are available by request.
7) Should I use a brass bolt or a galvanized steel one for outdoor electrical connections?
Brass is the choice where corrosion and galvanic compatibility matter, grounding bushings, bonding jumpers, copper lugs, damp or chemical environments, because it will not rust and it pairs well with copper. Galvanized or plated steel carries more tensile load for structural fastening. The JBRHC43 is a brass bolt, so treat it as an electrical and corrosion fastener rather than a structural one.
8) What is the exact part number to reorder these 5/16-18 brass hex bolts?
Order Metallics part JBRHC43, in the JBRHC series of brass hex bolts. That number covers the 5/16-18 x 1 size in the 100 count jar.
