Spindle and Cotter Pin

Copy pin, which appears as a machine element, is a standard machine element used in vibrating machines to secure the self-loosening of nuts and the loosening of pins and adjusting rings along their axis. It is made by doubling the wire made of hard steel. They are machine elements that prevent the nut from coming out as a result of bending the end of the bolts, which we call tipped, by passing them through the hole in the unthreaded area. They are shaped like tongs from semicircular cross-section wire rods. After being replaced, the glasses are left on the bent side to prevent them from coming out of the hole. After the other end comes out of the hole, the two ends are bent in the opposite direction.
