One side is unfinished for milling custom pulleys, threaded hubs, sprockets, collars, knobs, sensor targets, or just about anything imaginable; the other side is a one-piece clamping coupling for mounting whatever you’ve created to your shaft. Slide these ends onto your shaft and tighten the clamping screws for a secure hold that won’t damage your shaft.

Use flanged ends to make objects with larger ODs than straight ends, or add mounting holes to create a custom mounting flange for connecting components.

Ends for keyed shafts have keyways that firmly grip the shaft’s key to eliminate slipping. They handle higher torque than ends for round shafts.

Carbon steel ends are easier to machine than stainless steel. They have a black-oxide finish that adds a layer of rust resistance but should be used in primarily dry environments.

Stainless steel ends provide the most corrosion resistance but are more difficult to machine than steel.
