Our keys are machined metal fasteners used to transfer torque from a shaft to gears where tight tolerances and functionality are vital. They are precisely a fail-safe device to ensure that the key breaks before the gears do, cutting replacement costs down significantly. Woodruff keys are used in a variety of applications including, lawn and garden equipment, automobiles, trucks, pumps, electric motors, agricultural equipment and other heavy equipment. They are used more often than machine keys in automated assemblies, such as automotive, because they are easier to feed and maintain tight tolerances. No matter the application though, the key's job is the same, to transfer the torque by locking the gears into the crank shaft.
