Metallics JBHC10 Bolts 1/4-20 x 5 HXBT St-zn (Jar 100)

The JBHC10 is a 1/4-20 hex bolt, so 20 threads per inch on a 1/4 inch nominal diameter. Any standard 1/4-20 nut, coupling nut, or tapped strut channel fitting threads onto it. The thread is made to ASME B18.2.1-1996, which is the dimensional standard for square and hex bolts, so it mates with off-the-shelf 1/4-20 hardware rather than a proprietary thread.

The JBHC10 is steel with a zinc finish. Zinc plating is a mild corrosion coating, fine for dry interior work, electrical rooms, panel and strut mounting, and occasional damp. It is not the right pick for continuous wet exposure, coastal air, or anything submerged or in chemical contact. For those, specify stainless or hot dip galvanized instead.

No. The JBHC10 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project has a domestic sourcing clause, this bolt will not satisfy it and you need a domestically produced fastener instead.

Head width across flats runs 0.425 to 0.438 inch, which is a 7/16 inch wrench or socket. Head type is a plain hex, so a standard open-end, box, or 7/16 socket drives it. No internal drive, so there is nothing to strip out if you need to back it off later.

They ship as a jar of 100, and the jar is the order minimum, so this is a bulk pack rather than a loose count. One jar runs 7.41 lbs. The jar format is what makes it practical on a service truck or a shop shelf. Other sizes and quantities are available by request if 1/4-20 x 5 in hundreds is not what the job needs.

No, the jar holds 100 hex bolts only. Nuts and washers are separate line items, so order 1/4-20 hex nuts and 1/4 inch flat washers alongside it if the connection is a through bolt rather than into a tapped hole or strut nut.

They are catalogued for the electrical, plumbing, heating and air conditioning trades. In practice that means strut and trapeze hangers, mounting panels and boxes to blocking, securing equipment feet, and anchoring brackets where a long general purpose bolt with a nut on the back side is the simplest fix. Property maintenance crews keep a jar on hand for the same reason.
