Split Pins are simple yet effective fastening components used to secure nuts, bolts, or other fasteners in place, preventing loosening due to vibration or rotation. Made from high-quality steel or stainless steel, they provide reliable holding power and long-lasting durability.
The pin features a split design that allows it to be easily inserted into pre-drilled holes and bent at the ends to lock in position. Split Pins are widely used in machinery, automotive, agricultural equipment, and general mechanical assemblies.
