It also gives material guidelines and h
10、ardness requirements, and specifies the designation of flat ejector pins. Ejector pins with cylindrical head are specified in ISO 6751; shouldered ejector pins are specified in ISO 8694. 2 Dimensions The dimensions of flat ejector pins shall be in accordance with the indications of Figure 1 and Tabl
