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 Inserts—Washer inserts also protect rod ends. They’re commonly known as retaining safety washers.

Conical Inserts—Conical inserts help position rod ends between receiving forks, straps, and clevises.

Two-Piece Shaft Collars


For Round Shafts	For Keyed Shafts

Attach these collars anywhere along your shaft, which helps when other components are already installed or you can't access the end. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.

Chrome-Plated Carbon Steel—Resist moisture and mild cleaning solutions better than zinc-plated collars.

SAE Washers

Originally designed for the automotive industry, these washers conform to SAE sizing standards. They generally have smaller diameters than USS washers to fit in cramped spots and are thinner to create more precise gaps. Washers distribute pressure under screws and nuts to protect your mounting surface.

Steel

Corrosion-Resistant Chrome-Plated Steel—The brightest, shiniest finish we offer, this plating has a mirror-like appearance that is often used in decorative applications. It resists salt water and chemicals better than zinc plating and is less likely to wear off.

USS Washers

These washers meet USS sizing specifications and typically have larger diameters than SAE washers. As a result, they accommodate larger screws and nuts and distribute pressure across a wider surface area. They are also thicker, so they withstand heavier loads and span wider gaps when used as spacers.
