Metallics JBRHC49 Bolts 1/4-20 X 1-1/4 Hxbt Br (Jar 100)

Solid brass. The 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 wet or corrosive locations, where a brass bolt will not rust-seize the way a plain steel one does and keeps a conductive, dissimilar-metal-friendly connection to brass lugs and bus. It is softer than steel, so torque it by feel rather than running it down with an impact driver.

Head width across the flats is 0.428 to 0.438 inch, which is a 7/16 inch wrench or socket. Head height is in the 0.150 to 0.163 inch range with 0.16 inch of wrenching height, so there is not a lot of hex to grab, use a six-point socket or a box wrench rather than an adjustable to avoid rounding the brass.

Packed 100 per jar, and 100 count is the order minimum, so the jar is the smallest unit sold. The jar is the usual shop or van pack for this kind of small brass fastener, it keeps the count together instead of loose in a bin.

Yes. The JBRHC series brass hex bolts are offered in other sizes and quantities by request, so if you need a shorter 1/4-20 for a thin enclosure wall or a longer one to pick up a spacer, ask for the length you need rather than stacking washers under this 1-1/4 inch one.
