Metallics JBHC40 – Frequently Asked Questions
1) What thread does the Metallics JBHC40 hex bolt use, and will it take a standard 5/16-18 nut?
The JBHC40 is a 5/16-18 hex bolt with UNC coarse threads at 18 threads per inch, made to ASME B18.2.1-1996. Any standard 5/16-18 coarse nut or tapped 5/16-18 hole will thread onto it.
2) What wrench or socket size fits the head on this 5/16-18 Metallics hex bolt?
Head width across flats measures 0.484 to 0.500 inch, so a 1/2 inch wrench or socket is the fit. Head height runs 0.195 to 0.211 inch, which is worth knowing if you are driving it in a tight channel or against a strut flange.
3) Is a zinc plated steel hex bolt like this one OK for outdoor or damp electrical work?
The JBHC40 is steel with a zinc finish, which is a plated coating for indoor and protected dry locations. It will handle incidental moisture, but for sustained outdoor exposure, wet locations or coastal air you want hot dip galvanized or stainless hardware instead.
4) How many bolts come in a jar of Metallics JBHC40, and can I buy a smaller count?
They ship as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. Metallics does offer other sizes and quantities in the BHC and JBHC line by request if 100 of this size is not what you need.
5) Does the Metallics JBHC40 hex bolt meet Buy American requirements on a federal job?
Metallics lists the JBHC40 as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your specification requires a single documented origin, request the mill paperwork for the lot you receive.
6) How much does a jar of 100 Metallics 5/16-18 hex bolts weigh for shipping or stocking a service van?
The jar comes in at 2.02 lbs, with the container measuring 3 inches long by 3 inches wide and 2.7 inches high. Light enough to keep a few sizes of the BHC and JBHC line on the truck without eating payload or shelf space.
