Cotter Split Pins – Secure Locking Fasteners for Mechanical Assemblies

Cotter split pins (also known as split pins or cotter pins) are simple but highly effective mechanical fasteners used to lock nuts, bolts, clevis pins, and other components in place. Once inserted through a drilled hole, the two prongs are bent apart to prevent loosening due to vibration or movement.

Manufactured by JLHY, our cotter split pins are widely used in automotive, machinery, agricultural equipment, construction, and industrial assembly systems where reliable safety locking is required.
