Never exceed the permissible working loads. Before using hollow section fasteners, always check that the steel structure can withstand the required loads.
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 spanner. The hollow section fastener is only approved for one-time use!
We recommend the BoxSokTM special tool for installation."
