Yes. The B-Line AWA-25-325 is made to be installed through the fixture, so you can drill through the mounting hole of a strut bracket, conduit clamp or channel and set the anchor in place.

A wedge anchor like the AWA-25-325 is a through-fixture anchor: you drill through the bracket and the concrete in one pass, drive it, and torque the nut. That is quick for new work and for anything you can hold in position. A drop-in or internally threaded anchor sits flush in the slab and takes a threaded rod or bolt, which is what you want when the fixture has to be removable, when you need the rod to hang down, or when you cannot leave a stud protruding. For strut hung on all-thread from a deck, an internally threaded anchor usually wins; for bolting a clamp or bracket flat to a wall or slab, the wedge anchor is the simpler part.
