Metallics JBHC58 – Frequently Asked Questions
1) What thread does the Metallics JBHC58 hex bolt use, and will it take a standard 5/16-18 nut?
It's a 5/16-18 coarse thread (UNC), 18 threads per inch, so any standard 5/16-18 nut or tapped 5/16-18 hole takes it. Measured shank outside diameter runs 0.298 to 0.324 inch. Thread conforms to ASME B18.2.1-1996, the dimensional standard for square and hex bolts, so it interchanges with any other bolt built to that spec.
2) Do these bolts qualify for a Buy American or ARRA funded job?
No. The JBHC58 hex bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. On a federally funded project with domestic sourcing requirements you'll need a domestically produced fastener instead.
3) What wrench size fits these 5/16 inch hex bolts?
The hex head measures 0.484 to 0.500 inch across the flats, which is a 1/2 inch wrench or socket. That is the standard head size for a 5/16 inch hex bolt, so no odd tooling is needed on the truck.
4) How many bolts come in a jar of Metallics JBHC58, and can I buy a smaller count?
JBHC58 ships as a jar of 100 of the 5/16-18 x 5-1/2 hex bolts, and the jar is the minimum order unit. The jar weighs 12 lbs. Metallics does make other sizes and quantities in the BHC and JBHC range available on request, so if you need a shorter length or a bulk box instead of a jar, ask.
5) What is a 5/16-18 x 5-1/2 hex bolt long enough to do on an electrical install?
At 5-1/2 inches of length under the head, it's sized for stacking through depth: strut and backplates, wood blocking, through bolting a box or panel assembly, or clamping an insulator or standoff where a 1 or 2 inch bolt bottoms out. It's a general purpose fastener Metallics lists for the electrical, plumbing, and heating and air conditioning trades. Remember the thread is coarse 5/16-18, so order matching nuts and washers separately if you don't have them on the truck.
