The DynaSetâ„¢ Drop-In Anchor is an all steel, medium duty, displacement setting, expansion anchor designed to provide a permanent anchorage point in concrete. Its internal thread allows it to be used with both machine bolts and threaded rod, placing no restrictions on fixture thickness. The flanged version (zinc plated only) has a retaining lip to keep the anchor flush with the surface of the substrate. This also allows for consistent threaded rod drop lengths.
