Clevis pins are headless or headed cylindrical fasteners designed for use with clevises—U-shaped connectors with holes at each end. The pin inserts through the aligned holes to create a pivoting or hinged connection between components. A cross-hole at the opposite end accepts a cotter pin or split pin to secure the assembly and prevent accidental disengagement.
