Push-On Retaining Caps

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

Push-On External Retaining Rings

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

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.

Single-Turn Spiral External Retaining Rings

Slide these rings into place with one twist—no tools required—for applications with high thrust loads.

Side-Mount External Retaining Rings

Also known as E-style rings.

Wide-Grip Side-Mount External Retaining Rings

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.

Single-Turn Spiral Internal Retaining Rings

Slide these rings into place by hand with a single twist for applications with high thrust loads.

Push-On Internal Retaining Rings

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

Rectangular Push Nuts for Tapping Screws

Rectangular Push Nuts

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

Side-Mount External Retaining Ring Assortments

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.

Caps and Plugs

Rebar Caps

Keep personnel safe from protruding rebar and pipe. Made of rigid plastic, these durable safety caps are bright orange or yellow for excellent visibility.

Metal Square Plugs

More durable than plastic plugs, these provide the most protection from abrasion and impact. Use them to eliminate sharp edges and create a finished look on metal fence and machine-guard posts. Drive them in place with a hammer for a secure fit.

Tag Rings

Loop these rings onto tags.
