A clevis pin combination comprises a clevis made of aluminum alloy; and a pin made of steel. This combination of parts and materials results in lighter weight and improved performance of maximum load carrying capacity over similar combinations of all aluminum or all steel. The clevis further comprises a first clevis leg having a first clevis aperture in a first clevis end and a second clevis leg having a second clevis aperture in a second clevis end. The second clevis end is spaced apart from the first clevis end forming an open end. A curved portion connecting the first clevis leg and the second clevis leg forms a closed end. The first clevis aperture and the second clevis aperture are axially aligned and the steel pin is sized to fit through the first clevis aperture and second clevis aperture allowing pivoting movement between the clevis and the pin. The clevis may be substantially U-shaped. At least the curved portion of the clevis may by significantly wider than it is thick, such that it is flat in cross-section. Alternatively, the clevis may be significantly wider than it is thick, such that it is flat in cross-section. The curved portion or the entire clevis may be formed of a single piece of solid aluminum bar stock bent into a U-shape, forming a weldless and seamless U-shaped clevis. |
