Metallics JBHC57PL – Frequently Asked Questions
1) What thread and size is the Metallics JBHC57PL hex bolt?
The JBHC57PL is a 5/16-18 x 2-3/4 inch hex bolt, so 18 threads per inch on a 5/16 coarse (UNC) thread. Thread dimensions follow ASME B18.2.1-1996, and the measured outside diameter runs 0.298 to 0.324 inch. It takes a standard 5/16-18 nut; it will not thread into an 18-8 fine-thread (5/16-24) nut.
2) Is this bolt plated or bare steel, and can I use it outdoors?
Plain finish steel, meaning no zinc or galvanized coating. Keep the JBHC57PL to dry interior work such as strut, enclosure, and panel mounting. For exterior, damp, or corrosive locations choose a zinc plated or hot dip galvanized 5/16-18 bolt instead, since bare steel will rust.
3) What wrench or socket size fits the head on this 5/16-18 hex bolt?
Head width across flats measures 0.484 to 0.500 inch on the JBHC57PL, which is a 1/2 inch wrench or socket. The head is a plain hex, no washer face flange and no driver recess, so it is wrenched from the outside.
4) How many bolts come in a jar of Metallics JBHC57PL, and can I buy fewer?
The JBHC57PL ships as a jar of 100 bolts, and 100 count is the order minimum, so it is sold by the full jar rather than per piece. The jar is a bench-friendly pack for a van or shop shelf. Metallics does make other sizes and quantities in the BHC and JBHC series on request.
5) Does this Metallics bolt meet Buy American and ARRA requirements on a public project?
Metallics lists the JBHC57PL as compliant for both Buy American and ARRA purposes. Country of origin is China. On federally funded or state work, submit those two compliance flags with the origin to your specifying authority, since some agencies apply stricter domestic-content rules than others.
6) Is this the right bolt for mounting electrical enclosures and strut channel?
That is what the BHC and JBHC series is stocked for. It is a plain steel hex bolt carried as an electrical supply item, 5/16-18, which is the common thread for strut nuts, channel nuts, and enclosure mounting hardware. Buy the matching 5/16-18 nuts, washers, or channel nuts separately; only bolts are in the jar.
7) What does a full jar of these 5/16-18 x 2-3/4 bolts weigh for shipping or van stock?
A jar of 100 JBHC57PL bolts comes in at 6.59 lbs. The pack itself is listed at 7.25 inches high and 4.5 inches across, so it fits a standard van bin or shelf without decanting.
