Cotter Split Pin:4.0 x 40mm - DIN 94/Steel/ZPL

This cotter split pin is manufactured from steel and manufactured to DIN 94 standards with a nominal diameter of 4.0mm and a length of 40mm. The surface is finished with ZPL, which provides a protective coating for general corrosion resistance in mechanical applications. Buyers select this specific size and finish when a standard metric cotter pin is required for securing components without the need for complex locking mechanisms. It serves as a reliable replacement for worn or lost hardware in existing assemblies that specify this particular gauge and length. To choose the correct unit, verify that the mounting hole diameter matches the 4.0mm pin diameter and that the 40mm length allows sufficient leg projection for proper bending and locking. Ensure the ZPL finish meets the environmental requirements for your storage or operational conditions.
