The undercut anchor consists of an anchor sleeve and the corresponding hexagonal screw with locking tooth head made of stainless steel A4.

The drill hole, anchor sleeve and screw length must be matched to the desired setting depth and the selected plate holder. Only the use of parts that belong together makes assembly quick, easy and safe.
The anchor sleeve, which is compressed in the lower area, is inserted into the borehole together with the prescribed plate holder.
With light pressure on the plate holder (to lock the anchor), the screw is screwed in. The locking toothing of the screw digs into the plate holder as a screw lock.
By screwing in the screw in a controlled manner, the anchor sleeve is widened to the initial dimension so that it rests on the entire surface of the façade slab in the undercut area of the drill hole. After installation , the anchor sits in the undercut drill hole without spreading pressure, i.e. the clasp can still be rotated with a certain amount of force.
