Metallics BHC73G – Frequently Asked Questions
1) What thread does the Metallics BHC73G hex bolt take, and will a standard 5/8 inch nut thread onto it?
The BHC73G is a 5/8-11 hex bolt, meaning 11 threads per inch, which is standard UNC coarse thread for 5/8 inch diameter. Any 5/8-11 coarse nut will thread on. Thread form follows ASME B18.2.1-1996. Measured shank diameter runs 0.605 to 0.642 inch.
2) Is the Metallics BHC73G hex bolt acceptable on a federally funded or Buy American job?
The BHC73G is flagged compliant for both ARRA and Buy American. Country of origin is listed as multiple, so if your spec requires a single declared origin, treat the compliance flag as the governing record on the part.
3) What size wrench or socket fits the head on this 5/8-11 galvanized hex bolt?
Across-flats width on the Metallics BHC73G head measures 0.906 to 0.938 inch, so a 15/16 inch wrench or socket is the fit. Head height is 27/64 inch, worth knowing if you are working in a tight channel or behind a strut.
4) Can I use these galvanized hex bolts outdoors or in a damp mechanical room?
Yes. The BHC73G is steel with a galvanized finish, which is the usual choice for exterior strut, rooftop equipment supports, and damp plant rooms where plain zinc plate would rust out. Pair it with galvanized nuts and washers so you are not mixing coatings at the joint.
5) How are these 5/8-11 x 3 hex bolts packaged, and is there a minimum order?
They ship as a box of 25. The order minimum on the BHC73G is 100 count, so the practical buy is four boxes. Other sizes and quantities are available by request if the job needs a different length or diameter.
6) Are these hex bolts meant for electrical and mechanical trade work or for structural steel connections?
Metallics lists the BHC73G for electrical, plumbing, heating and air conditioning work, which is where a galvanized 5/8-11 hex bolt earns its keep: hanger rods, trapeze supports, unistrut assemblies, equipment bases. It is a general purpose trade fastener, not a specified structural bolt, so a structural connection calling out a particular bolt grade needs the bolt named on the drawing.
7) What hole size should I drill or punch for a 5/8-11 hex bolt?
Shank outside diameter on the BHC73G runs 0.605 to 0.642 inch, so a nominal 11/16 inch hole clears it without binding. Going to 5/8 exactly will not pass the bolt once galvanizing is on the shank.
8) What does a box of these 5/8-11 x 3 galvanized hex bolts weigh for handling and shipping?
A box comes in at 5.78 lbs, with carton dimensions of 7.25 x 6.75 x 3.25 inches. Useful if you are staging multiple boxes on a cart or hitting a per-package weight limit on a jobsite delivery.
