Metric threaded fasteners being developed in North America differ in some important respects from current ISO standards. Significant weight savings can be achieved on M10, M12, and M14 Hex Cap Screws by adopting smaller hex head sizes. A formed hex cap screw is also proposed as an alternative design. Reduced diameter body cap screws with full body diameter shoulders offer both weight savings in longer lengths and increased elastic elongation. The 12 spline flange screw design is reviewed. A style 1, Property Class 9, hex nut is proposed to be made of AISI 1018 - 1020 steel without heat treatment.
