The plastic shaft may be a molded plastic rod made from an engineered resin material, and may take one of several different shapes, such as a round or “T-shaped” cross-sectional profile. There may be a metal cap on both ends of the plastic shaft, and each of the metal caps may be shaped with a stamping process and hardened. The caps may be crimped onto the ends of the plastic shaft or they may be insert molded. Preferably, either method provides a part with excellent TIR and surface finish, and which meets torque requirements. Preferably, the assembly is lightweight and meets all requirements and the resin material is high temperature resistant and oil resistant.
