Machinable Shaft Ends

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.

Straight End


For Keyed Shafts	For Round Shafts

1215 Carbon Steel—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.

For Keyed Shafts—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.

Set Screw Rigid Shaft Couplings

Slide these couplings onto the end of your shaft and tighten the set screws to secure. Set screws bite into the shaft to hold the coupling in place. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

Black-Oxide 1215 Carbon Steel

Black-oxide steel couplings have some corrosion resistance.

4 Set Screws Included—Couplings with four set screws hold better than couplings with two set screws.

Threaded Rod Collars

To install, thread these one-piece collars onto the end of your shaft. They clamp evenly around the shaft to create a strong, mar-free hold. Tighten the clamping screw to secure.

Black-Oxide 1215 Carbon Steel—Black-oxide steel collars have some corrosion resistance.

Threaded Two-Piece Rod Collars

Install these collars 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.

Black-Oxide 1215 Carbon Steel—Black-oxide steel collars have some corrosion resistance.
