microPEM® Concealed Rotary Standoff

The new microPEM® Concealed Rotary Standoff technology from PennEngineering®* minimises axial force by using a rotating installation tool that applies torque to move the sheet material over a flange. The material flows inward to the body of the part.

The product allows fasteners to be installed in thin sheet metal - leaving one side of the panel aesthetically clean with no or minimal marks - while still providing strong pullout and torque resistance.

*Only in Poland, Rumania
