- Easy and simple installation with a tangential impact driver, especially in overhead applications
- Flush-mount installation
- Internal thread enables a variety of applications with metric fasteners.
- Fastenings can be removed at any time, the internal thread anchor can be fully removed if necessary
- Flexible and versatile for use in a variety of base materials (concrete, solid block, wood)
- Low embedment depth, reduces reinforcement hits and drilling effort
- Low spacing and edge distance due to very low expansion effect
We recommend the use of a suitable tangential impact driver for installation. The recommended nominal torque must be observed. For applications in which the drill hole is to be sealed against water ingress or where the anchor is to remain in the base material permanently, WIT-PE 1000 can also be used.
