The ADI-37SS4 is a 3/8 inch anchor, meaning it accepts 3/8 inch threaded rod or a 3/8 inch bolt in its internal thread. The anchor body measures .375 inch in diameter and 1.1875 inch in length, so your embedment depth has to be at least that anchor length in sound concrete, plus you need clearance for the setting tool to seat the plug flush.

Yes, overhead use is exactly what it is called out for. The ADI-37SS4 is a drop-in anchor for solid concrete used in overhead applications, which is the normal way threaded rod is dropped from a deck to carry strut, conduit hangers, or pipe rings. It is also UL Listed.

The ADI-37SS4 is type 304 stainless steel, which is the usual choice for damp, washdown, and unheated exterior locations where a zinc-plated carbon steel anchor would rust and stain the concrete. In heavy chloride exposure (coastal spray, pool chemical rooms, de-icing salt) 316 stainless is the step up, but 304 covers most garage and exterior canopy work.

Yes, and that is the main reason to pick a drop-in over a wedge anchor. The ADI-37SS4 sets flush in the concrete and the threaded rod or bolt screws into it, so you can back the rod out and reinstall at the same point later. A wedge anchor, by contrast, leaves a stud permanently sticking out of the slab.
