Metallics DIA12M Anchors 1/2 Drop-In Ancr St-zn (Box 1000)

Yes, that is the normal use for a 1/2 inch internally threaded drop-in anchor like the DIA12M. You drill and clean the hole in cured concrete, drop the anchor in flush, expand it with a setting tool, then thread in 1/2 inch rod for trapeze hangers, strut, cable tray or fixture supports. Because the rod threads in and out, it suits overhead work where you want the anchor set before the hanger goes up.

Zinc plated steel, not stainless. That is fine for dry interior concrete, but for exterior, wet or corrosive locations you want a stainless anchor instead.

The DIA12M ships as a box of 1,000 anchors. It is a bulk pack intended for production work, so it suits a full conduit or tray run rather than a handful of point fixes.

No. The DIA12M is a solid-base concrete anchor; it relies on expansion against solid material, so it is wrong for hollow block cells, brick voids or drywall. Use a toggle or hollow-wall anchor there, or a sleeve anchor rated for the base material.

Yes. The anchor body stays in the concrete and the 1/2 inch rod or bolt threads in and out of it, so equipment can be unbolted and remounted using the same anchor. That is the main reason crews pick an internally threaded drop-in over a wedge anchor, where the stud is permanent.
