Metallics JBHC28G – Frequently Asked Questions
1) Will the JBHC28G hex bolt take a standard 3/8-16 nut?
Yes. It is threaded 16 threads per inch on a 0.360 to 0.388 in. shank, which is 3/8 in. coarse (UNC), and the thread is made to ASME B18.2.1-1996. Any off-the-shelf 3/8-16 hex nut, lock nut or coupling nut will run on it.
2) Do nuts and washers come with these 3/8-16 galvanized hex bolts?
No. The JBHC28G jar is bolts only, 50 pieces. Order matching 3/8-16 galvanized hex nuts and 3/8 in. flat or lock washers separately so the plating matches and you do not mix zinc-plated hardware with galvanized on an exterior run.
3) What wrench size do I need for the Metallics JBHC28G 3/8-16 hex bolt?
Across the flats the hex head measures 0.544 to 0.562 in., which is a 9/16 in. wrench or socket. Standard shop size, no special tooling.
4) Is a galvanized hex bolt like the JBHC28G okay for outdoor or damp locations?
The bolt is steel with a galvanized finish, which is what you want for exterior conduit racks, rooftop supports, damp mechanical rooms and unconditioned spaces. For submerged, chemical or coastal splash-zone work, stainless is the better call.
5) How many bolts come in a jar of Metallics JBHC28G?
Fifty bolts per jar, and the jar is the minimum order, so you buy in multiples of 50 count. The jar packaging keeps them from scattering in a gang box or on a cart.
6) How much does a jar of 50 of these 4 inch hex bolts weigh?
6.78 lbs for the jar. Useful if you are loading a van or figuring freight on a multi-jar order for a job.
7) Can I get the Metallics JBHC28G hex bolt in a different length or a bigger jar?
The JBHC28G itself is fixed at 3/8-16 x 4 in. galvanized, 50 per jar, but other sizes and quantities in the BHC and JBHC hex bolt series are available by request.
8) Where are Metallics JBHC28G hex bolts made?
Country of origin is China. Worth knowing up front if your project has domestic-sourcing language in the specification.
