Use these caps to hold components in place and protect shaft ends.

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.

Also known as C-style and crescent rings, these rings have a small shoulder to fit in tight spaces.

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

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.

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.
