Technical Usage
Cotter pins are primarily used as locking devices to prevent components from loosening under vibration or stress. These pins are inserted through pre-drilled holes and bent at the ends to secure assemblies, such as clevis pins, axles, and shafts. The corrosion-resistant properties of Stainless Steel 304 make them ideal for outdoor and marine applications, as they can withstand exposure to moisture, salt, and chemicals without degrading. Their robust design ensures reliable performance in high-stress and high-temperature environments.
