  • The new thread geometry ensures smooth screwing into the concrete and thus greater efficiency

  • The fastest type of fastening for medium and heavy loads

  • Three effective anchorage depths allow flexible application

  • Attachments can be adjusted up to twice retrospectively, for example to be able to align staircase railings or anchor plates (observe installation instructions)

  • Minimum spacing and edge distances due to very low expansion effect

  • Attractive, flush-mount installation possible
Notice

From size 8, we recommend the use of a suitable tangential impact screwdriver for installation. The recommended nominal torque must be observed. When used outdoors, the drill hole can be sealed with WIT-BS injectable mortar.
