Metallics JBHC59G – Frequently Asked Questions
1) What thread does the Metallics JBHC59G hex bolt use, and will it take a standard 3/8 nut?
It is a 3/8-16 hex bolt, 16 threads per inch, made to ASME B18.2.1-1996 for hex bolt dimensions. Any standard 3/8-16 UNC nut or tapped 3/8-16 hole will thread onto it. Note the 16 TPI: standard UNC for 3/8 is 16, so this is the coarse thread most strut, channel nuts, and electrical hardware use, not fine thread.
2) Is a galvanized Grade 2 steel bolt suitable for outdoor or damp electrical work?
The JBHC59G is steel with a galvanized finish, which gives it corrosion resistance for damp and exterior runs, rooftop equipment, and unconditioned mechanical spaces. It is a Grade 2 bolt, so it is a general purpose fastener for hanging and mounting work rather than a high strength structural connection. If the drawing calls out Grade 5 or Grade 8, this is not the bolt.
3) Will a 1-1/4 inch long bolt be long enough for my strut and bracket stack-up?
The JBHC59G is 1-1/4 inches of overall bolt length, so once you subtract the nut and washer you have roughly an inch of usable grip. That covers channel plus a single bracket or clamp ear in most electrical and mechanical hanging work, but it is short for stacked plates or thick wood blocking. For a thicker stack, order a longer length in the same BHC/JBHC series.
4) Does this Metallics hex bolt meet Buy American or ARRA requirements for a public project?
The JBHC59G is flagged compliant for both Buy American and ARRA in the manufacturer's data, with country of origin listed as multiple. That is the pair of flags institutional and government procurement normally needs on a fastener line item.
5) What wrench or socket size fits the head on this 3/8-16 hex bolt?
The hex head measures 0.544 to 0.562 inches across the flats, which is the 9/16 inch standard hex for a 3/8 bolt. A 9/16 socket or open end wrench is what you want on it.
6) How many bolts come in a jar of Metallics JBHC59G, and can I order a partial quantity?
They ship 100 to a jar, and 100 count is the order minimum, so the jar is the smallest unit. Metallics notes other sizes and quantities are available by request if 1-1/4 inch length or the jar count does not suit the job.
7) What hole size do I need to drill for a 3/8-16 hex bolt like this one?
The bolt's measured outside diameter runs 0.360 to 0.388 inches, so a 3/8 inch clearance hole is tight and a 7/16 inch hole is the normal clearance drill for through-bolting. Threaded holes and strut channel nuts need to be 3/8-16.
8) What kind of work are Metallics JBHC galvanized hex bolts intended for?
Metallics lists this bolt for the electrical, plumbing, heating and air conditioning trades. In practice that is mounting panels, boxes, straps, hangers, clamps, and equipment to strut or structure, where a galvanized general purpose Grade 2 hex bolt is what the job calls for rather than a structural grade.
9) How much does a 100 count jar of these 3/8-16 bolts weigh for shipping?
A full jar comes in at 4.97 lbs. Useful if you are totalling out a van load or a freight line for a large fastener order.
