Yes. The B-Line AWA-37-275 is designed to be installed through the fixture, so you can use the mounting hole in the bracket, channel or clamp as your drill guide, then drop the anchor straight through and tighten the nut. That saves you laying out holes separately and re-aligning the part.

The AWA-37-275 wedge anchor is UL Listed, which matters if you're hanging conduit, cable tray or fixture supports under an inspection. It's catalogued by Eaton B-Line as electrical fastener hardware.

The AWA-37-275 is zinc plated carbon steel. Zinc plating is a light corrosion coating meant for dry interior use; for exterior, damp, or corrosive environments you want a stainless or hot dip galvanized anchor instead. For indoor mechanical and electrical support it's the standard choice.

A wedge anchor like the B-Line AWA-37-275 is for solid poured concrete and is rated by B-Line for heavy and medium duty all purpose anchoring. It expands against the hole wall as you torque the nut, and the threaded stud stays above the surface, so it's best when you're bolting a bracket or channel down permanently. Use a drop in anchor instead when you need a flush internally threaded insert you can unbolt and rebolt, and a sleeve or toggle type when the base is hollow block or brick rather than solid concrete.
