Internal expansion anchor (female) provided to the standards GB/T 22795 and ETAG 001. The anchor is installed inside a drilled hole in solid concrete and receives a bolt; tightening the bolt drives a cone into the sleeve.

The cone forces the sleeve to expand against the bore, generating a frictional bearing between anchor and concrete. Typical applications include fixing equipment, brackets and pipelines to solid concrete substrates.

Confirm required size, bolt compatibility, material and load data before specification.
