M12 ALL-METAL LOCKNUT BZP(10)

Special features of prevailing torque type hexagon nuts: Is a one piece all metal class 10 nut, acc. to DIN 980 V. The locking is achieved by local radial deformation of a part of the nut. First the nut runs freely on the thread untill the locking part is reached, after which the clamping force increases gradually to a maximum. This progressive locking action with distributed pressure over a large surface prevents damage of the thread. Resistant to shocks, vibrations and dynamic loads. Re-usable.
