Open these rings, pass them over the end of a shaft, and release to spring into the groove.

These rings meet military specification MS 16624.

No groove is required for these rings—their thick profile helps them grip the shaft.

Also known as E-style rings.

These rings are reinforced to withstand faster rotation than other side‐mount retaining rings. Also known as reinforced E‐style rings.

Also known as bowed E-style rings, these have a curved design that works like a spring, taking up play for a tight hold.

These coiled rings can be wound into place on a shaft without tools.

No groove required—press these rings onto the end of a shaft for a firm grip.

The wide flange provides better load distribution than standard external push rings and can be used to cover oversized holes. Also known as thread cutting nuts.

Often used with small engines, heavy equipment, and power transmission, these external retaining rings have speared ends to help you install and remove them.

Also known as constant-section rings, these rings have open ends and a profile that does not taper like other external retaining rings. Use them with linear bearings on support rail shafts.

Squeeze these rings to place them in the groove inside a bore or housing.

Thicker and stronger than standard internal retaining rings, these withstand greater thrust loads.

With teeth along the inside, these retaining rings hold chamfered shafts inside the housing of your equipment.

Thicker than standard spiral rings, these rings withstand greater forces.

Pull these rings open with retaining ring pliers, pass over the end of a shaft, and release to spring into a groove.

Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface.

Assortments include pliers to install external and internal rings.

Pull ring ends together with retaining ring pliers and place into the bore of a shaft or housing.

With flexible teeth that slide smoothly over threads of any pitch, these push nuts can be used alone for light-duty applications or as a jam nut.

Also known as flat-style speed nuts, these have large sides, so they're easy to push over threads by hand.

A flange distributes the load over a large area and reduces stress where the nut meets the material surface.
