There are different solutions available to temporarily join multiple parts. You can use a threaded fastener, for instance. The problem with threaded fasteners, though, is that they are oftentimes difficult to remove. If the parts require frequent joining and separation, you may want to choose an alternative solution, such as a bent hitch pin.

Bent hitch pins also known as R-clips, bent hitch pins are metal clips that are used to temporarily join multiple parts. They consist of a single piece of metal with two arms. Most of them are made of metal wire. One of the arms is straight, whereas the other arm is bent. Bent hitch pins are also known as R-clips because they resemble the shape of the letter R.

Bent hitch pins work like other types of clotter pins. The straight arm is pressed into the hole of a part, which allows the bent arm to press into a separate and adjacent hole. The bent hitch pin then “snap” into place, thereby securing the part or parts until it’s removed.

Most bent hitch pins are used in fastening applications that involve a round shaft. The natural curvature of bent hitch pins makes them ideal for these applications. With a round shaft, the straight arm is inserted into a straight hole in the center of the shaft. Doing so will allow the bent arm to wrap around the curved side of the shaft.
