Designed to deal with fasteners that are prone to loosening in frequent vibrations or unstable environments, Keps Nuts’ unique claw-shaped structure simulates the function of a locking washer, which can firmly engage the contact surface and significantly increase friction.
Keps Nuts and nylon lock nuts both belong to the category of lock nuts, but they have their own characteristics in locking principle and structural design.Keps Nuts realizes the locking function by adding a toothed washer at the bottom, while the nylon locking nut is embedded with a nylon ring at the top. During the installation process, the nylon ring is squeezed and deformed, thus effectively preventing the nut from loosening.
