IE • Expansion Insert

How to fix

Phase 1

The insert is placed in a cavity which is either drilled or moulded in: the well.

Phase 2

The insert is forced into the well by axial pressure, deforming slightly in the process. The insert will be flush with the material to avoid possible removal due to lever effect.

Phase 3

As the screw goes in, the insert returns to its original shape, the locking pyramids are forced into the material, providing holding force and torque resistance. Select a screw long enough to effectively force the locking pyramids into the material. The screw must never come into contact with the bottom of the well.
