Cotter Pins

Cotter pins -- also known as split pins -- are thin metal pieces used to lock castle nuts in place on machine parts fitted to a shaft. They may be simple in design, but cotter pins are the key to preventing rotary parts from becoming loose and falling off during use. Let us help you identify the appropriate design for your needs, so you can always have a ready selection of pins on hand.
