Bilateral Machine Keys

Bilateral machine keys are cut from key stock to lengths under 12 inches long. Bilateral indicates that the key’s tolerance can be slightly larger or slightly smaller than a specified size while remaining within the tolerance range. While these keys do not match ANSI spec, they tend to be the most desirable grade in maintenance repair operations. 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.
