Abstract

This invention relates to a self-threading nut which is utilized to hold a replacement shock absorber within the cylinder housing of a vehicular suspension system commonly referred to as a MacPherson strut suspension system. The nut includes a generally cylindrical main body portion having a tapered threaded portion on the inner wall thereof. A plurality of apertures are formed in the side wall of the main body portion to provide positive lead angle cutting edges and permit the removal of metal chips therefrom. The lower end of the nut is formed with an inner diameter corresponding to the outer diameter of the cylinder, and the upper end wall includes a plastic bushing having an inner diameter corresponding to the diameter of the piston rod of the replacement shock absorber. The inner diameter of the lower end and the plastic bushing cooperate to center the nut as threads are formed on the outer wall of the cylinder.
