The clevis Pin and How it Works

The clevis pin is a simple but durable fastener that interlocks 2 or more components together. Unlike a bolt, the clevis pin is not threaded. It is fitted into pre-drilled holes located on the components it is intended to fasten. The pin is then placed through the holes of the components. A flat-headed flange on the top of the clevis pin secures one connection of the interlocked components while an R pin (shaped like a capital letter "R") or a cotter pin is placed through a pre-drilled, perpendicular hole in the shank of the clevis pin at the other end to lock it in place. This allows pivot-point movement of the components while securing them together. The R pin can be easily removed without tools and the clevis pin can be disengaged for a quick-release/quick-connect procedure. Cotter pins would require bending back into shape, take a little longer to remove and may require a pair of pliers do manipulate depending on their thickness.

What Clevis Pins Are Used For

Clevis pins can be found on many types of machinery that we use every day and may not even realize. They are used to connect C-type shackles with holes on each edge of the C. The pin is pressed into the holes, is locked with the R pin or cotter pin and forms a D. Industrial farm equipment commonly use clevis pin connections on multipurpose functional attachments. garden and lawn tractors use clevis pins to fasten mower decks to the tractor and to the hydraulic lift adjuster. Hinge-type connections use clevis pins in common equipment, like gas grill covers. Sport enthusiasts may notice clevis pins on equipment they use, such as backpacks, to customize quick adjustments. The medical industry uses clevis pins on equipment for needed height or vertical adjustments. Clevis pins can be found in wheel axles of equipment that requires retention of the wheel without the accurate precision of high speed required. Sailboats and other marine vehicles commonly use clevis pin connections for quick adjustments and connections to equipment on board.

Types of Clevis Pins

The most common clevis pin found in equipment and gear is the cornpicker or standard clevis pin. This is the flange-headed pin with a single hole located at the end of the shaft. The type of the flange head may come in four different styles: button or mushroom-headed, flat-headed, truss-headed or headless. The headless clevis pin has two holes at either end and uses two R or cotter pins to interlock the device. The adjustable clevis pin has several holes drilled through the shank, offering multiple placement of the locking R or cotter pin. Cotterless clevis pins have a spring-loaded ball bearing at the end, which presses inward to allow connection, and then the ball bearing pops back into place to lock. Grooved clevis pins have precision-machined channels (or grooves) on one or both ends of the clevis and use a hair-type or C-type retention clip in place of the R or cotter pins.
