Also known as flat-style speed nuts, these have a large surface to distribute loads better than standard and flanged external push rings.

Crimp-On External Retaining Rings

Also known as X-washers, place these rings into the groove and squeeze tight with pliers to form a 360° closure.

Clip-On External Retaining Rings

Slide these rings into a groove near the end of the shaft and the tab locks them in place.

Bearing Retaining Nuts

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

Bearing Retaining Jam Nuts

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.
