B-Line AWA-50-375 Eaton series fastener hardware and accessories, Heavy and medium duty all purpose anchor, Zinc plated carbon steel ,3⁄8" x 3-3⁄4", Anchors can be installed through the fixture

Yes. The AWA-50-375 is made to be installed through the fixture, so you can position the channel, bracket, or base, drill through the mounting hole into the concrete, and drive the anchor without repositioning anything. That saves the layout step and keeps hole alignment exact.

The AWA-50-375 is zinc plated carbon steel, which is a dry-interior and light-exposure finish. It's fine for mechanical rooms, parking structures under cover, and general indoor concrete. For constant wetting, coastal air, pool chemistry, or chemical exposure, go to a stainless wedge anchor instead; the zinc plating will corrode in those conditions.

No. A wedge anchor like the AWA-50-375 sets by expanding a clip against the wall of a drilled hole and needs solid, cured concrete to develop its hold. In hollow block, brick, or grout-filled CMU the base material will crumble or the anchor will spin. Use a sleeve anchor or a screw anchor rated for masonry in that case.

The anchor is 3-3/4 inches long. Embedment plus the thickness of whatever you're fastening plus the nut and washer all have to come out of that 3-3/4 inches, so thick base plates or stacked strut eat into your usable embedment.

Yes, the Eaton B-Line AWA-50-375 is UL Listed. That matters on electrical and institutional jobs where the inspector wants listed support components rather than generic hardware.

A wedge anchor of this type is a one-piece assembly with the expansion clip, nut, and washer already on it, so the anchor itself is complete. What you supply is a carbide hammer-drill bit matched to the anchor diameter, a blow-out bulb or vacuum to clear the hole, and a torque wrench or socket to tighten the nut once it's seated.
