Key Steel

Tensile and strong, our Key Steel is typically used in parallel keys. In mechanical applications, Key Steels are used to maintain the driving torque between couplings, gears, and sprockets and can also be used with moving shafts and pulleys, mechanical drums, and propellers.

Key Steels are presented in a long length of square-shaped steel and work on very tight tolerances. To choose the appropriate Key Steel for your needs, you should be aware of its cross sectional size and length. Take note that Key Steels are available in metric and imperial sizes. Use our list of Key Steel products below to find the one that best suits your needs.
