DEWALT 09220-PWR Calk-In 1/4 X 20, 100 Pack

It is a 1/4 inch anchor with internal 1/4-20 threads, so a standard 1/4-20 machine bolt or threaded rod threads straight into it. Nothing is supplied with the anchor itself, so order the bolts separately in the length your fixture and base material require.

The difference is removability. A wedge anchor leaves a stud sticking out of the concrete permanently; the Calk-In sets flush and keeps the thread inside the hole, so the bolt can be backed out and the fixture taken off for service, then re-bolted to the same anchor. That matters for equipment, panels and conduit supports that get pulled for maintenance. It is also a shallow embedment anchor, so it suits thinner slabs or where you cannot drill deep.

No. DEWALT lists this one for light duty anchoring, so it is the wrong choice for structural connections, seismic bracing or heavy suspended equipment. Use it for light fixtures, small brackets, conduit clamps and similar attachments, and step up to a heavy duty mechanical anchor or adhesive anchor where the load is significant.

The anchor body is alloy steel with a zinc finish, which is a standard indoor and protected-location coating. It is not a stainless or hot dip galvanized anchor, so for wet exterior exposure, pool rooms or coastal work pick a stainless anchor instead.

A Calk-In is a caulk-in type anchor: it drops into the drilled hole and is expanded with a setting punch before the bolt goes in. Threading the bolt in alone will not set it. Keep the matching 1/4 inch setting tool on the cart with the anchors, along with a carbide bit sized to the anchor.

It is hardware, not a tool. The DEWALT 09220-PWR is a non-energy-using anchor with no battery involved, despite the DEWALT power tool branding. What you receive are threaded concrete anchors.
