Cotter Pin – Product Introduction

Product Overview
Cotter pins, also known as split pins, are simple yet essential mechanical fasteners used to secure other fasteners or components in place. Typically inserted through a pre-drilled hole in a bolt, shaft, or clevis pin, the ends of the cotter pin are then bent to lock it in position. Cotter pins are widely used in automotive, agricultural, marine, machinery, and general hardware applications for their reliability and ease of use.
