There are two main types of clevis pins: threaded and unthreaded. Unthreaded clevis pins have a domed head at one end and a cross-hole at the other end. A cotter pin is used to keep the clevis pin in place. Threaded clevis pins have a partially threaded shank on one end and a formed head on the other. The head has a lip, that acts as a stop when threading the pin into the shackle, and a flattened tab with a cross-hole. The flattened tab allows for easy installation of the pin and the cross-hole allows the pin to be moused. A bolt can function as a clevis pin, but a bolt is not intended to take the lateral stress that a clevis pin must handle. Clevis pins and bolts are designed to withstand shearing forces. Clevis pins should be closely fitted to the holes in the clevis to limit wear and reduce the failure of either the pin or the clevis.
Clevis fasteners from SEF are high-precision fasteners that are used when a design needs a superior finish. The pins are designed using cold heading quality wire. They can also be used in drastically extreme temperatures. These pins are similar to bolts but are only partially threaded and come with a cross hole to be fastened using a split pin. Another component of the clevis pin is the tang, which fits in the clevis and is held in place by the pin. When it is used in combination with the pin in the clevis, it is called a shackle. These pins are mostly used in the design of farming equipment and rigging sailboats. It is also used to create remote controls when the controls have to be attached to servos.
