Frequently Asked Questions
Cotter pins serve as positive locking devices that prevent nuts, bolts, and pins from loosening or backing out due to vibration. They provide mechanical safety by physically blocking component movement once installed and bent properly.
Insert the cotter pin through the pre-drilled hole in the bolt or shaft, then bend the two prongs in opposite directions around the component. Ensure the bends are sufficient to prevent the pin from slipping out, but avoid over-bending which could weaken the pin.
Cotter pins are generally designed for single use. Once removed, they should be replaced with a new pin as the bending and straightening process can work-harden the metal, making it more brittle and prone to failure upon reinstallation.
