Metallics BHC71G – Frequently Asked Questions
1) Is the BHC71G a coarse thread bolt, and will it take a standard 5/8 nut?
It is 5/8-11, which is UNC coarse thread at 11 threads per inch, so any standard 5/8-11 coarse nut threads on. Thread form is built to ASME B18.2.1-1996. If the nuts on your job are 5/8-18 fine thread, they will not engage.
2) What hole size do I drill or punch for the BHC71G?
Shank outside diameter runs 0.605 to 0.642 inch, so an 11/16 inch hole clears it with normal bolt-hole slop. Do not try to pull it through a 5/8 inch punched hole.
3) What size wrench or socket do I need for the Metallics BHC71G hex bolt?
The hex head measures 0.906 to 0.938 inch across the flats, so a 15/16 inch wrench or socket is the right fit. Head height is 27/64 inch, which matters if you are working in a tight pocket or against a flange.
4) Can these galvanized hex bolts be used outdoors or in a damp mechanical room?
Yes. The BHC71G is steel with a galvanized finish, which is the usual choice for exterior strut, pipe hanger, and rooftop equipment work where plain steel would rust. For continuous immersion or heavy chemical exposure you would step up to stainless instead.
5) How many bolts come in a box of Metallics BHC71G?
They ship 25 to a box, and 25 is also the order minimum, so one box is the smallest quantity. Other sizes and counts can be had by request if 2-1/2 inch is not the grip length you need.
6) Are these hex bolts intended for electrical and mechanical trade work, or general construction?
Metallics lists the BHC and JBHC series for the electrical, plumbing, heating, and air conditioning trades, which is where 5/8-11 galvanized hex bolts turn up most: strut and channel connections, trapeze hangers, transformer and equipment pads, and pipe support assemblies.
7) Where is the Metallics BHC71G hex bolt made?
Country of origin is China. Both the ARRA and Buy American compliance fields on the BHC71G carry a C code, so if your project has a domestic sourcing requirement in the spec, confirm it against that code before you submit the bolt for approval.
8) What does a full box of 25 of these 5/8 hex bolts weigh for shipping or carrying up a ladder?
A box of 25 comes in at 6.65 lbs, so it is a one-hand carry. Nuts and washers are not included, so order those separately in 5/8-11.
