To reduce the mass of the widely used plastic caps there were compared two thread profiles and various outer shapes of them analyzed by FE models applying axisymmetric, linear elastic finite elements plus contact elements. The result of this investigation by reducing mated threads and modifying the cap's outer geometry produced about 40% reduction in mass.
