These metal collars are stronger than plastic shaft collars. They clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.
Chrome-plated steel collars have moderate corrosion resistance with a bright finish.

These metal collars are stronger than plastic shaft collars. The two-piece design allows you to install them anywhere on a shaft without removing components or having access to the ends of the shaft. Collars clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screws to secure.
Zinc-plated steel and chrome-plated steel collars have moderate corrosion resistance with a bright finish.

Without changing the ID, these inserts handle some misalignment on rod ends. They attach to your rod end to move your fastener away from the rod-end body.
Washer-style inserts also protect rod ends. They’re commonly known as retaining safety washers.
Cone-style inserts help position rod ends between receiving forks, straps, and clevises.
