Metallics BHC86M – Frequently Asked Questions
1) What thread does the Metallics BHC86M hex bolt use, and will it take a standard 1/2 inch nut?
The BHC86M is a 1/2-13 hex bolt, meaning a 1/2 inch nominal diameter at 13 threads per inch, which is standard UNC coarse thread. Any standard 1/2-13 coarse nut or tapped 1/2-13 hole will accept it. The thread is made to ASME B18.2.1-1996.
2) Is a 3/4 inch long hex bolt long enough for strut channel or a panel bracket?
At 3/4 inch of overall length under the head, the BHC86M is a short bolt built for thin stack-ups, think a single thickness of strut channel, a bracket flange, or a clamp body with a nut on the back. Grip length is consumed quickly: on anything thicker than about 1/2 inch of combined material you will not get enough thread into the nut. For deeper assemblies order a longer length in the same 1/2-13 thread.
3) Does a box of 1,000 of these 1/2-13 bolts qualify as Buy American or ARRA compliant?
Metallics lists the BHC86M as both ARRA compliant and Buy American compliant. Country of origin is China. If your project specification requires domestic melt and manufacture rather than the ARRA/Buy American designation the manufacturer assigns, confirm which standard your contract is written to before you submit.
4) Will this bolt pass through a 1/2 inch punched hole?
Shank outside diameter is 0.482 to 0.515 inches. At the top of that range the bolt is slightly over a nominal 1/2 inch, so a true 1/2 inch drilled hole can be tight. Use a 9/16 inch hole, or the standard 9/16 inch punched hole in strut and channel, for clean clearance.
5) What wrench or socket size fits the head of the 1/2-13 Metallics hex bolt?
Head width across flats measures 0.725 to 0.750 inches, so a 3/4 inch wrench or socket is the right tool. Across corners the head runs 0.826 to 0.866 inches, which is what you need to clear if you are driving it in a recessed hole or counterbore.
6) Is zinc plated steel OK for outdoor or damp electrical work?
The BHC86M is steel with a zinc finish. Zinc plating handles indoor and dry or sheltered locations well and gives moderate protection in occasional damp. For sustained outdoor exposure, wet locations, or coastal air, step up to hot dip galvanized or stainless, since plated zinc is a thin sacrificial coating rather than a heavy barrier.
7) How many bolts come in a box of Metallics BHC86M, and can I buy fewer?
These ship as a box of 1,000 bolts, and 1,000 is the order minimum. It is a bulk pack meant for shops and contractors fastening repetitively rather than for a single repair. Other sizes and quantities can be arranged by request.
8) Are nuts or washers included with the Metallics BHC86M hex bolts?
No. The box contains 1,000 hex bolts only. Order matching 1/2-13 hex nuts, and flat or lock washers if your assembly calls for them, as separate line items.
9) How much does a full box of 1,000 of the 1/2-13 x 3/4 hex bolts weigh?
A full box runs 73.9 lbs, with carton dimensions of 11.5 x 10.75 x 11.5 inches. Worth knowing before you plan a shelf, a job box, or a one-man carry up a ladder.
