Stainless Steel-Assembly pins Depending on the requirement there are three washer types to choose from, which place the assembly pin in an axial position in its insertion direction. With the washer with eyelet (Type E) the assembly pin and a corresponding GN 1024 spring cotter pin can be secured to prevent loss using a retaining cable or ball chain. The washer with mounting shackle (Type L) simultaneously acts as loss protection and anti-rotation protection.
