Datasheets(X)
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.
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 wrench. The hollow section fastener is only approved for single use.
We recommend the BoxSokTM special tool for installation.
