Flow drilling

Screw connections without previous machining

Screwdriving joining system RSF for flow-drilling screws

Detachable screw connections without prior processes
Composite construction methods and one-sided accessibility of joints are challenges for the joining technology in body construction. The robot-assisted screwdriving system for flow-drilling screws RSF ensure high-strength connections in a joining process. Screw connections can be accomplished with or without pilot holes – material variations and manufacturing tolerances are compensated.

High strength and flexibility
A metric thread is cut directly into the elements to be connected. This produces detachable joints – dismantling is possible at any time. The RSF method allows screw connections with high tightening forces and loosening torques. The process is freely configurable.
