When installed, these keys fill oval keyways completely, reducing stress on the key and shaft. The rounded ends make it easy to slide gears, hubs, and other components into place. These are also known as feather keys.

Machine Keys

Straight keys, with a square or rectangular cross section, are the most common type of key. Install them in keyways to transmit torque from shafts to gears and other components.

Woodruff Keys

Woodruff keys work well near shaft shoulders and on tapered shafts. These keys have a rounded shape that makes them easy to remove when parts need to be taken apart frequently. Use them in light duty applications to connect gears and other components to shafts. Also known as half moon keys.

Tapped Rounded Machine Keys

Thread a screw through the tapped hole to pop these keys out of a keyway. When installed, they fill oval keyways completely, reducing stress on the key and shaft. The rounded ends make it easy to slide gears, hubs, and other components into place.

Tapered Gib Keys

These keys have a tapered body that wedges in to the keyway for a more secure fit than standard machine keys. The gib head makes them easy to remove when parts need to be taken apart frequently, such as for maintenance or prototyping.

High-Profile Woodruff Keys

Feet prevent these keys from rocking in the keyseat. Woodruff keys work well near shaft shoulders and on tapered shafts. Use them in light duty applications to connect gears and other components to shafts. Also known as hi-pro keys.

Machine Key Stock

Cut this stock to length to create the machine key you need. Straight keys, with a square or rectangular cross section, are the most common type of key. Install in a keyway to transmit torque from shafts to gears and other components.

Step Machine Key Stock

When a keyway is damaged, cut a new, wider one. This key stock is stepped to match repaired keyways in shafts or gears. Cut it to length to create the machine key you need.
