Metallics JBRHC59 Bolts 3/8-16 X 1-1/4 Hxbt Br (Jar 100)

The JBRHC59 is a 3/8-16 x 1-1/4 inch brass hex bolt, so 16 threads per inch on a 3/8 inch diameter. It threads into any 3/8-16 tapped hole or nut. It will not work in a 3/8-16 UNC hole's close cousin, 3/8-16 is the pitch stated here, so check the tap on your enclosure or lug before ordering a different pitch.

The JBRHC59 gives you 1-1/4 inches of bolt length, so it suits thin stacks, think a brass lug on a plate, a bonding jumper, or a channel bracket. Allow for the nut and any washers inside that 1-1/4 inches. If your assembled stack plus nut engagement runs past about an inch, step up to a longer length in the JBRHC series rather than stretching this one.

Brass through and through. Both the material and the head color on the JBRHC59 are listed as brass, which is why these turn up in grounding and bonding work, water-contact assemblies, and anywhere a steel bolt would rust or set up galvanic trouble against brass or copper parts.

These ship as a jar of 100 pieces, and 100 count is the minimum order, so the jar is the smallest unit. For MRO cribs and electrical shops that is the point of the jar pack: one container on the shelf instead of loose bagged counts. Other sizes and quantities in the series are available by request.

Hex head, so they drive with an open end, box, or socket wrench rather than a screwdriver or Allen key. That matters in tight electrical enclosures where there is no room to swing a ratchet, a nut driver or stubby box wrench is usually the better call on a 3/8-16 hex bolt.

Country of origin on the JBRHC59 is China. Worth knowing up front if you are buying against a federal, state, or institutional spec that puts a domestic-content condition on fasteners, since origin is usually the first line the reviewer checks.
