Tensioning Washers
Robust Tensioning Washers for High-Load Applications
With consistent adherence to DIN 6796 standards, Lesjöfors Stock Spring US produces tensioning washers with solid dimensions, uniquely designed for incorporation in medium to high-load screw joints. The remarkable spring force from our washers offers effective reinforcement against relaxation and creep, particularly in joints subjected to significant stress and thermal-induced movements.
When the stakes are high, our tensioning washers can effectively replace ordinary lock washers. They can be stacked in series or parallel—series stacking to increase the available deflection, while parallel stacking enhances the force. The ultimate installation goal is to get these washers as flat as possible.
