Oversize Machine Keys

Oversize machine keys, or broad machine keys, are cut from key stock to lengths under 12 inches long. Oversize indicates that the key is either at or slightly larger than a specified size while remaining within the tolerance range. These machine keys are often used when a custom fit is needed or desired for an oversize key way. They are also used in field repairs and for worn key ways. They are specifically designed to fail as a safety mechanism to save more expensive components. Standard sizes are ready to use without any cutting or filing
