B-Line B250HDG Eaton series strut fittings and accessories, 3.32" Height, 5.35" Length, 1.62" Width, .77lbs, Steel, Four hole open angle, 60 deg, Thickness 1/4 in, Hot-dipped galvanized

The B250HDG is hot-dipped galvanized steel, which is the finish specified for exterior, damp, and corrosive-environment strut work. That makes it suitable for rooftop mechanical supports, parking structures, and exterior pipe racks where a plain or electro-galvanized fitting would rust at the cut edges. Hot-dip coating covers the punched holes and edges, not just the faces.

Yes, that is the job this fitting is built for. Diagonal bracing between a vertical strut and a horizontal run rarely lands on a square corner, and the B250HDG sets that joint at a fixed 60 degrees in 1/4 inch steel. Because the angle is fixed, confirm your brace geometry is actually 60 degrees; if the angle varies job to job, use an adjustable or swivel-type strut fitting instead of a fixed-angle bracket.

No. The B250HDG ships as the galvanized steel bracket only. You order your own hardware for each of the four holes, normally 1/2 inch strut bolts with channel nuts and springs, and match the plating to the bracket by using hot-dip or galvanized hardware on exterior runs so you don't set up a dissimilar-metal problem.
