Simple and Straightforward Installation
Insert the COTTER PIN through the prepared hole and bend the two legs outward to secure it in place. No threads or special fastening tools are required.
Prevents Components from Becoming Detached
A COTTER PIN can restrict axial movement of castellated nuts, bolts, shafts, and connecting pins, helping prevent components from slipping out during vibration or operation.
Easy to Inspect Visually
After installation, it is easy to visually confirm whether the COTTER PIN has been inserted correctly and whether the legs have been properly bent, making assembly inspection and equipment maintenance more convenient.
Easy to Remove and Replace
During maintenance, the bent legs can be straightened and the pin removed. This makes COTTER PINS suitable for mechanical structures that require periodic disassembly. Replacement with a new pin is recommended if the original pin has become deformed or fatigued.
Wide Range of Applications
COTTER PINS are commonly used in machinery, automotive and motorcycle components, agricultural machinery, construction equipment, furniture hardware, and various linkage assemblies.
