Marine Fasteners 1/4 X 4 SS COTTER (5/PK) is a high-quality cotter pin, also known as split pins or cotter keys, which are rounded-headed bent pins that slide into a hole. Once inserted into the hole, the two ends bend in opposite directions, deforming the pin and making it difficult to remove. This cotter pin is used to prevent axial movement along the shaft.
