Metallics JBHC47G Bolts 1/2-13 X 1-1/2 Hxbt Galv (Jar 50)

It's a 1/2-13 bolt, meaning a 1/2 inch diameter body with 13 threads per inch, which is standard UNC coarse thread. Any 1/2-13 coarse nut or tapped 1/2 inch coarse hole will thread onto it. Threads are made to ASME B18.2.1-1996, so dimensions match standard inch hex bolt practice.

Grade 2. That's the standard low-carbon steel strength class used for general-duty electrical, plumbing, and HVAC hanging and bracket work, which is exactly the field application Metallics lists for the BHC and JBHC series. If a drawing or seismic detail calls for Grade 5 or Grade 8, these won't meet it, you'd need a higher-grade bolt marked accordingly.

Metallics flags the JBHC47G as both Buy American compliant and ARRA compliant, which is what a government, school, or healthcare procurement file usually needs on record. Country of origin is listed as multiple, so if your contract requires a single named origin, confirm that separately against the shipment documents.

These are steel bolts with a galvanized finish, which is the usual choice for exterior strut, pipe hangers, and damp mechanical rooms where plain steel would rust. For full submersion or chemical exposure, stainless is the better call. Pair galvanized bolts with galvanized nuts and washers so you don't set up a dissimilar metal problem.

They ship 50 to a jar, and 50 each is the order minimum, so the jar is the smallest unit. Metallics notes other sizes and quantities in the BHC and JBHC line are available by request.

A jar of 50 comes in at 5.46 lbs, so an MRO crib can plan shelf loading accordingly. Handy number if you're kitting several jars onto a van or a service cart.
