Application area

For fastening to hollow sections or other hard-to-reach components. The fastener is especially suitable for applications where the installation point is only accessible from one side.

Instructions

The connection is produced by tightening the screw while bracing the sleeve collar, resulting in expansion of the sleeve. The tightening torques can be applied using a torque spanner. The hollow section fastener is only approved for one-time use!


We recommend the BoxSokTM special tool for installation.
