Metallics BHC85 – Frequently Asked Questions
1) What thread size and pitch is the Metallics BHC85 hex bolt, and will a standard 3/4-10 nut fit it?
The BHC85 is a 3/4-10 hex bolt, 4 inches long, so 10 threads per inch on a 3/4 inch diameter. That is standard UNC coarse thread, so any 3/4-10 coarse nut or coarse-tapped channel will thread onto it. Measured body diameter runs 0.729 to 0.768 inch. Thread form follows ASME B18.2.1-1996.
2) Do these Metallics bolts meet Buy American or ARRA requirements for a government job?
No. The BHC85 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For federally funded work carrying domestic sourcing clauses you will need a documented domestic-origin fastener instead.
3) What size wrench or socket do I need for a 3/4-10 Metallics hex bolt?
Across-flats width on the BHC85 head is 1.088 to 1.125 inch, which is a 1-1/8 inch wrench or socket. Head height is 15/32 inch, so allow that much clearance above the surface plus room to swing the wrench.
4) Can I use these zinc-plated bolts outdoors or in a wet mechanical room?
Zinc plating on steel gives moderate corrosion resistance, which is fine for indoor and dry or occasionally damp interior locations. For sustained outdoor exposure, roof-mounted equipment, or wash-down and coastal environments, step up to hot-dip galvanized or stainless of the same 3/4-10 x 4 size instead.
5) How many bolts come in a box of Metallics BHC85, and can I buy just a few?
They ship as a box of 25 each, and 25 is the order minimum, so the box is the smallest purchasable unit. Metallics notes other sizes and quantities are available by request.
6) How much grip length do I actually get from a 4 inch long 3/4-10 bolt?
The 4 inch dimension on the BHC85 is the shank length measured from under the head, not overall, so a hex bolt's 15/32 inch head sits on top of that. Subtract the thickness of what you are clamping plus washers and nut thickness to confirm you have enough thread engagement. If you are stacking strut, a channel nut and double washers, run the math before ordering.
7) Does the BHC85 come with nuts and washers?
No. It is bolts only, 25 to a box. Order matching 3/4-10 coarse hex nuts and 3/4 inch flat or lock washers separately to complete the assembly.
8) What does a box of 25 Metallics 3/4-10 x 4 hex bolts weigh for shipping?
Listed weight is 14.82 lbs for the box. Carton dimensions are 7.25 in by 6.75 in by 3.25 in, so it is a small, dense package.
