Spring cotter pins GN 1024 are used for the axial fixing of bolts and axes and as distortion guard, e.g. for crown nuts DIN 935.
Owing to their double winding, spring cotter pins of Type D have a flatter spring characteristic and are therefore easier to install. Also, a retaining rope including a key ring can be attached to the double winding to safeguard the Spring cotter pin against loss.
