A tenter clip has a jaw pivot shaft having a pair of molded bearing surfaces of superior strength, wear resistance and stability under high temperature operating conditions. The method for manufacture of the jaw pivot shaft includes knurling recesses formed in the shaft prior to applying plastic bearing material to the recesses by injection molding and finishing machining the pin by centerless grinding.
