Steel Drop-In Anchor

Zinc-plated carbon-steel drop-in anchors — internally threaded expansion sleeves set flush with the concrete surface. After setting with the correct tool, a metric bolt or threaded rod screws into the anchor. Listed M6–M20. Commercial drop-in geometry (not an ETA-marked proprietary capsule).

Typical for overhead hangers, pipe supports, and equipment where a flush internal thread in the slab is wanted and the fixture is attached later. They need a correct hole diameter, depth, and setting punch — an unset drop-in has no capacity. For through-fixing of a fixture in one operation, a sleeve or S-type anchor is usually faster. Edge distance and concrete quality govern safe load; we quote the hardware, not a design resistance.

Select metric size (and length where listed). Quote with quantity and destination; matching bolts or 8.8 threaded rod can be included.
