Metallics BHC80G Bolts 5/8-11 X 5 Hxbt Galv (Box 25)

No. The BHC80G is bolts only, 25 to the box. Hex nuts, flat washers, and lock washers in 5/8 inch are ordered separately, so plan on matching galvanized 5/8-11 nuts and 5/8 washers to keep the coating consistent through the connection.

Twenty-five bolts per box. It is sold as a box quantity, not loose by the piece, so a job needing 40 anchors of this size takes two boxes.

Yes, the BHC80G is galvanized. The zinc coating gives it corrosion resistance suited to exterior strut, rooftop equipment supports, and damp or unconditioned spaces where a plain steel bolt would rust. For fully submerged or chemically aggressive service, stainless is the better call.

Metallics catalogs it as BHC80G. That is the manufacturer part number to quote when ordering the 5/8-11 by 5 inch galvanized hex bolt in the 25 piece box.

The 5 inch length is measured from under the hex head to the end of the bolt, so your total grip (combined thickness of the members, plus washers, plus enough thread to fully engage the nut) has to come in under 5 inches. Thick steel-to-steel connections, timber framing, and stacked strut assemblies are the usual uses at this length; for a thin two-plate joint a 5 inch bolt leaves a lot of exposed thread.

For a 5/8 inch diameter bolt, a standard bolt hole in steel is 11/16 inch, which gives the normal 1/16 inch clearance. In wood, an 11/16 inch hole also lets the shank pass without forcing. Pre-drilling to the bolt diameter exactly makes the galvanized threads bind on the way through.

A 5/8-11 hex bolt takes a 15/16 inch wrench or socket across the flats, which is the standard head size for that diameter. Worth knowing before you get on a lift with the BHC80G and a box of 25.
