You can install it straight through the fixture. The AWA-37-375 is designed so the hole can be drilled through the mounted item and the anchor driven in place, which means you line the bracket up once and do not have to pull it off to set the anchor. That is the practical difference between a wedge anchor and a drop-in or shield anchor, where the fixture has to come off before the anchor is set.

It is UL Listed. The AWA-37-375 is an Eaton B-Line fastener catalogued for electrical work, so it is the anchor used for hanging conduit straps, strut, boxes and light fixture supports where an inspector wants a listed fastener on the concrete attachment.

No. This is a wedge anchor for solid poured concrete only. It needs the hole wall to react against as the clip expands, so it should not be used in hollow CMU, brick veneer, drywall, or the flutes of a metal deck. For hollow block use a sleeve or toggle type anchor instead.

Zinc plated carbon steel is a dry interior finish. It handles normal indoor conditions fine, but for exterior work, wash-down areas, parking structures, or anywhere subject to standing moisture or chlorides, specify a stainless or hot dip galvanized wedge anchor instead. Zinc plating on carbon steel will corrode in those environments and a corroded anchor loses holding value.

A wedge anchor like the AWA-37-375 is a one-piece stud with an expansion clip at the base. It is for solid concrete, it sets by torquing the nut, and it can be driven through the fixture. A sleeve anchor expands over more of its length and is the choice for block or brick. A drop-in is a flush internally threaded insert that is set with a setting tool before the fixture goes on, used where you want a bolt you can remove and replace. For medium and heavy duty all purpose fastening into poured concrete, the wedge anchor is the standard pick.
