The GPM SSM42514 stainless steel screw shafts are intended for hobbyists and technicians requiring reliable replacement hardware. Dimensioned as M4x2.5x14, the parts provide a 5mm thread length with a 9mm shaft length, offering consistent engagement and improved wear resistance compared with softer fasteners. These shafts work well where corrosion resistance and repeatable fit are priorities in linkage and mounting points.
