M1.6 – M5-Brass Cotter (Split) Pin

Brass Cotter Split Pins, also known as cotter pins or split pins, are vital components in machine and automotive applications, primarily used to secure castle nuts and washers in place. These pins feature two prongs that are bent apart during installation, effectively locking the nut and washer in position to prevent them from loosening. Their design allows for easy insertion and secure fastening, providing a reliable solution for critical connections in machinery and automotive assemblies. The brass construction offers corrosion resistance, ensuring durability and longevity even in demanding environments.
