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. Using them in a closed keyway keeps them from sliding along the shaft axis. The rounded ends make it easy to slide gears, hubs, and other components into place. To install, press them in to place. Use them for permanent or high-torque applications, or to replace a key in a worn keyway. Keys are made of steel.
Undersized Tolerance—Undersized keys are good when you need a slightly looser fit or when you have an inconsistent keyway. Use them with parts you take apart frequently, such as for maintenance or prototyping. They meet DIN 6885 dimensional standards for undersized keys.
