Product application

 

The DIN 980V Stover Nut is a hex all-metal prevailing torque self-locking nut, available steel grades 8, 10 and 12.

They are available from M4 to M48 in standard pitch, fine pitch and extra fine pitch.

These locknuts are vibration resistant self-locking nuts, which are resistant to shocks, vibration and dynamic loads – and they can be reused a number of times.

The locking function is achieved by the deformation of part of the nut. The nut will run smoothly until it reaches the deformed part, after which the clamping force will increase.

Available as standard in metric sizes ranging from M4 onwards, with various finishes and pitches available to order.
