Metallics BHC39 – Frequently Asked Questions
1) What thread does the Metallics BHC39 hex bolt take, and will a standard 1/2-13 nut fit it?
The BHC39 is a 1/2-13 hex bolt, so 13 threads per inch on a 1/2 inch diameter, which is standard UNC coarse thread. Any standard 1/2-13 coarse nut or 1/2 inch tapped coarse hole will take it. Threads are made to ASME B18.2.1-1996, and the measured outside diameter runs 0.482 to 0.515 inch.
2) Is a Grade 2 zinc plated bolt strong enough for hanging pipe and conduit?
The BHC39 is Grade 2 steel with a zinc finish, which is the standard commercial grade used for electrical, plumbing and HVAC support work, exactly the field application it is listed for. Grade 2 is a low carbon, unmarked-head bolt, so it is fine for trapeze hangers, strut and general equipment mounting but it is not a substitute where a drawing calls out Grade 5 or Grade 8 for a structural or high-torque connection.
3) Do these Metallics hex bolts meet Buy American or ARRA requirements on a public job?
No. The BHC39 is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your project has domestic sourcing language in the spec, these will not pass; you need a domestically produced Grade 2 hex bolt instead.
4) What size wrench or socket do I need for the BHC39 hex bolt head?
Head width across the flats is 0.725 to 0.750 inch, which is a 3/4 inch wrench or socket. That is the usual across-flats size for a 1/2 inch hex bolt, so standard 3/4 inch impact sockets drive it.
5) Can I use these zinc plated hex bolts outdoors or in a wet area?
Zinc plating gives indoor and light moisture protection only. For a rooftop, a parking structure, a pool room or anything exposed to weather or washdown, specify hot dip galvanized or stainless instead; plain zinc will bloom white rust and then red in those spots. For dry interior mechanical and electrical rooms, zinc is the normal choice.
6) How many bolts come in a box of Metallics BHC39, and can I buy fewer?
They ship as a box of 100, and 100 count is the order minimum, so partial boxes are not broken. Other sizes and quantities can be had by request if 1/2-13 x 5 is not the length you need.
7) Are nuts and washers included with the BHC39 bolts?
No. The box contains hex bolts only, 100 of them. Order 1/2-13 hex nuts and 1/2 inch flat or lock washers separately to complete the assembly.
8) How much does a box of 100 1/2-13 x 5 hex bolts weigh for shipping or carrying up a lift?
A full box runs 29.8 lbs, and the carton measures 7.25 by 6.75 by 3.25 inches. That is a one hand carry but heavy for its size, worth knowing if you are staging several boxes on a scissor lift or a cart.
