Metallics JBHC61 – Frequently Asked Questions
1) What thread does the Metallics JBHC61 hex bolt take, and will a standard 3/8 inch nut thread onto it?
The JBHC61 is a 3/8-16 hex bolt, 16 threads per inch, made to ASME B18.2.1. That is the standard coarse 3/8 inch machine thread, so any 3/8-16 hex nut, coupling nut or tapped 3/8-16 strut fitting will run onto it. Measured shank outside diameter runs 0.360 to 0.388 inch.
2) Is a Grade 2 zinc plated bolt strong enough for hanging electrical conduit and HVAC supports?
The JBHC61 is a Grade 2 steel bolt with a zinc finish, which Metallics lists for electrical, plumbing, heating and air conditioning work. Grade 2 is the general purpose low carbon grade, fine for strut, hanger, box and bracket assembly. If a drawing calls out Grade 5 or Grade 8 for a structural or seismic connection, this is not the bolt for that detail.
3) Does the Metallics JBHC61 bolt meet Buy American or ARRA requirements for a public project?
No. The JBHC61 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For a federally funded job carrying domestic sourcing language, specify a domestic hex bolt instead.
4) Will a 3/8 inch wrench socket fit the head of the Metallics JBHC61 bolt?
The head is a hex with an across flats width of 0.544 to 0.562 inch, so it drives with a 9/16 inch wrench or socket.
5) Is the zinc plating on these hex bolts OK for outdoor or damp locations?
Zinc plated steel is what the JBHC61 carries, which suits dry interior and normally occupied mechanical and electrical spaces. For sustained exposure to weather, wet locations or corrosive atmospheres, step up to a hot dip galvanized or stainless 3/8-16 hex bolt instead.
6) How many bolts come in a jar of Metallics JBHC61, and can I buy fewer than that?
It ships as a jar of 50 pieces, and 50 each is the order minimum, so the jar is the smallest unit. Metallics notes other sizes and quantities are available by request.
7) What is the shipping weight of a 50 piece jar of 3/8-16 x 2-1/4 hex bolts?
A jar of the JBHC61 weighs 3.99 lbs, useful if you are building out a stocked parts crib or a van inventory by weight.
