Metallics M6206 Anchors 1/2 Smart-Di Drop-In Ancr C-St (Jar 50)

The M6206 is the 1/2 inch Smart-Di drop-in anchor, so it accepts 1/2 inch bolts or threaded rod (1/2-13 coarse thread is the standard pairing for a 1/2 inch drop-in). It is internally threaded, which is why it works for overhead threaded rod hanging of conduit trapeze, strut, and cable tray rather than a through-bolt style anchor.

For overhead threaded rod, the drop-in is the type you want. A drop-in like the M6206 sets flush in the concrete and leaves a 1/2 inch internal thread, so rod can be threaded in and backed out later without disturbing the anchor. A wedge anchor is externally threaded and studs out of the slab, which suits bolting a baseplate down but not accepting a length of rod. The tradeoff is that a drop-in has to be expanded with a matching setting tool after the hole is drilled and cleaned.

Yes, and it is not included with the jar of 50. A drop-in anchor expands only when its internal plug is driven down with a setting punch sized to that anchor, so you need the 1/2 inch setting tool plus a 1/2 inch anchor-rated hammer drill bit. Order the tool once, then the jars of anchors as you consume them.

Fifty anchors per jar. Metallics packages the 1/2 inch Smart-Di drop-in in a jar rather than a box, which is the pack type an electrician typically keeps on the van for overhead rod work.

Carbon steel. That makes it an interior, dry-location anchor for conduit and cable tray support; for damp, exterior, or corrosive locations step up to a stainless drop-in instead.

Yes, that is the main advantage of the drop-in over a stud-type anchor. Once the M6206 is expanded in the concrete it stays put, and the 1/2 inch rod or bolt threads in and out as many times as the job needs, so a trapeze can be dropped, relocated, and rehung on the same anchor.
