ANSI/ASME B 18.8.6M Cotter Pin

ANSI/ASME B 18.8.6M Cotter Pins, also known as split pins or cotter keys, are simple and widely used fasteners designed to secure bolts, nuts, and other types of fasteners in mechanical applications. They consist of a metal pin with a split at one end and two tines that can be spread apart after insertion through the aligned holes of a bolt or a similar fastening element. The split end prevents the pin from slipping out, thereby ensuring the stability of the fastened components.

Product Feature

Cotter pins are typically designed as a straight metal pin with a split end, forming two tines or legs.To install a cotter pin, the split end is inserted through the hole of a bolt or other fastener, and the two tines are then spread apart to prevent the pin from slipping out.Cotter pins are commonly made of metal, such as steel or stainless steel, to provide strength and durability.Cotter pins come in various sizes, and their dimensions are often standardized according to industry standards like ANSI/ASME B18.8.They are widely used in mechanical and automotive applications to secure components like castle nuts, slotted nuts, clevis pins, and other fasteners.Cotter pins are often reusable, making them convenient for applications where disassembly and reassembly are required.Depending on the material used, cotter pins can exhibit corrosion resistance, especially if made from stainless steel or other corrosion-resistant alloys.Cotter pins are simple yet effective fasteners, and their design allows for easy installation and removal, making them a practical choice in various industries and applications.
