Retaining Rings

Push-On External Retaining Rings

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

Push-On Retaining Caps

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

Rectangular Push-On External Retaining Rings

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

Flanged Push-On External Retaining Rings

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.

Push-On Internal Retaining Rings

No groove required—these rings have teeth that firmly grip the bore.

Nuts

Round Push Nuts

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.

Rectangular Push Nuts

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

Rectangular Push Nuts for Tapping Screws

Flanged Push Nuts

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

Hex Speed Nuts

Hex speed nuts can be gripped with a wrench for ease of removal.

Installation Tools for Press-Fit Nuts

These tools include everything you need to install press-fit nuts by hand.

Fastening Tools

Push Nut Installation Tools

Push nuts and retaining rings over threaded fasteners and shafts. These tools have a magnetized tip so nuts don't fall off as you slide them on.

One-Piece Socket Retaining Rings

The pin on these retainers is permanently connected to the ring, so they're less likely to dislodge when used with an impact wrench compared to two-piece retaining rings.

Two-Piece Socket Retaining Rings

Stretch-Fit One-Piece Socket Retaining Rings

Stock fewer sizes of retaining rings—these stretch to fit a range of socket diameters.
