Metallics DIABST38-SDS 3/8 Drop-In Ancr Sds- Plus Po

The DIABST38-SDS is a 3/8 inch drop-in anchor, so it accepts 3/8-16 threaded rod or a 3/8 inch bolt once set in the concrete. That makes it a common pick for hanging strut, conduit trapeze, and threaded-rod supported runs off a concrete deck.

This one is the SDS-Plus version, meaning the setting tool chucks straight into an SDS-Plus rotary hammer instead of being driven by hand with a manual setting punch. You still drill the hole, blow it clean, drop the anchor in flush, and expand the internal plug by driving the setting tool down until it bottoms out.

Drop-in anchors like the Metallics 3/8 SDS-Plus unit sit flush with the concrete surface and are internally threaded, so the rod or bolt can be removed and reinstalled later without disturbing the anchor. That is why electricians favor them overhead for threaded rod hangers. A wedge anchor is a through-fixture anchor with a permanent protruding stud, better when you are clamping a base plate down and never plan to take it off.

No. You get the anchor body only. The 3/8 inch rod, bolt, nuts and washers are ordered separately, and so is the SDS-Plus setting tool if you do not already have one on the truck.

Drop-in anchors are for solid concrete. The internal plug needs solid material around it to expand against, so hollow block, brick veneer, and any hollow wall board will not hold it. For hollow base material use a toggle or sleeve-type anchor sized for the substrate instead.

The anchor is set when the setting tool bottoms out and its shoulder stops against the top of the anchor lip, flush with the concrete. Drill to the anchor's full depth first and clear the dust before dropping it in, otherwise the anchor sits proud and the plug will not fully expand.
