A wedge anchor is drilled at the same nominal diameter as the anchor body, so the AWA-37-350SS4 at .375 inch diameter goes into a 3/8 inch hole in concrete. Drill the hole deeper than the intended embedment so drilling dust has somewhere to go, then drive the anchor and tighten the nut to expand the clip.

Yes. The B-Line AWA-37-350SS4 is a through-fixture anchor, so you can position the bracket or channel, drill straight through the mounting hole into the concrete, and drive the anchor without lifting the fixture back off. That saves a layout step on overhead conduit and strut runs.

No. A wedge anchor relies on a clip expanding against solid material, so the AWA-37-350SS4 belongs in solid poured concrete. For hollow block, brick, or hollow-core plank use a sleeve anchor or a toggle-type fastener instead, and for base material questions on a rated assembly check the engineer's detail.

The AWA-37-350SS4 is made from type 304 stainless steel, which is the usual choice for exterior, damp, and washdown locations where a plated carbon steel anchor would rust and stain the concrete. For chloride-heavy environments such as coastal exposure or pool chemical rooms, 316 stainless is the step up from 304.

UL Listed, yes. The AWA-37-350SS4 carries a UL Listing, which is what an inspector or institutional spec usually wants to see on anchors supporting conduit, raceway, cable tray, and light fixtures.

The AWA-37-350SS4 is rated by the manufacturer as a heavy and medium duty all purpose anchor, which covers typical conduit strap, strut bracket, and fixture support work. Overhead loads are normally anchored in pairs or fours per bracket rather than on a single point, and the governing load values come from the engineer or the spec on the drawing, not from the anchor's duty class alone.
