A tiedown hitch for trucks and the like includes a medial body portion having a longitudinal axis, with a hook portion extending from one end and an eye portion extending from the opposed end. An interior hook surface is provided with an insert having a relatively large radius, so that the rope or line cannot be abraded or damaged by engagement with the hook. The hook insert may comprise a channel member bent into an arcuate shape and pressed onto the interior hook surface. Alternatively, the interior hook surface may be chamfered to provide a smooth arcuate exterior face to engage the rope or line secured about the hook portion. The eye portion includes a closed interior slot extending generally coaxially with the longitudinal axis and dimensioned to receive the rope or line therethrough. The medial body portion includes an arcuate closed slot formed therein, the slot defining a single finger that serves as a cleat to secure the rope or line passing thereabout. To use the tiedown hitch, one end of a rope is secured to a cleat on the truck, and passed through the eye slot and wrapped about the cleat finger. The rope is then passed back through the eye slot, so that the tiedown hitch is anchored immovably with respect to the cleat securing the rope. The free end of the rope is then extended over or about the load, and secured about a second cleat on the truck. The free end is then passed around the hook portion of the tiedown hitch, and returned to the second cleat. The rope extends in three plies from the hook to the second cleat, so that a mechanical advantage of three to one is established. The free end of the rope is pulled to tighten the rope to the desired extent, and the free end is then tied to the second cleat or another nearby fixed object.
