The world-renowned Klincher Locknut was patented in 1943 and has been one of the primary products we manufacture since we acquired that business in 1998. Various versions of the Klincher Locknut are key components used in the manufacturing of jet engines for aircraft, turbines, turbochargers and other applications involving high temperature, high vibration and high stress. Nearly every major jet engine and aviation manufacturing company, including Pratt-Whitney, Rolls Royce, GE, Boeing, etc. use locknuts every day. The Klincher Locknut is a well-known and recognized brand throughout the aviation, aerospace, and many other industries and organizations, including the U.S. Military.
