The second end uses to connect the pin with an object.One end uses to connect the pin with the other pin.The standard pin has following two different ends. Due to its large surface, it has a good grip when connecting to other parts through the hand. These types of cotter pins may have curved or straight designs. You can also insert your finger in the ring located on the head and drag the pin out of the hole. The curved part is clamped on the outside of the shaft, and the straight part or section pushes to go into the shaft via a hole that holds the pin in place. This section is bent to make a ring or loop on the head, with a bent section balanced from the straight pin. The R-pin is a sprung pin that has a straight section.

It can be only one time for applications. It also uses as a brake for the clevis pin. The split cotter pin is usuallt installed in pre-drilled parts and secured with a deformable tine. These types of pins are constructed of semicircular wire, which is bent over the flat side to make bulbous heads. The split cotter pin is one of the most popular types of cotter pin. Cotter pin with a key 1) Split Cotter Pins.The cotter pin has the following major types: They are easy-to-use fasteners that only require a drilled bolt (a drill is required if the bolt doesn’t have a hole), pliers, and a castle nut. It can use for a variety of applications. The cotter or split pin works on the locking mechanism. These pins are most commonly used to secure clevis pins, bolts, and other fasteners that might come loose because of movement or vibration. When the pin compresses, it generates friction which prevents the pin from loosening and helps to work smoothly.Ĭotter pins are commonly used in engineering and mechanical systems to secure different components. The term tapered represents that the pins compress as they enter the holes. They are tapered or wedge pins that are driven into the holes. In most cases, these pins are employed to stop axial motion along the shaft. Cotter pins are available in different designs and sizes. This pin is inserted via the aligned holes in the parts and then bent to prevent it from falling out. The cotter or split pin is made of thick wire with a semicircular cross-section. In the USA, the cotter pin is also known as a split pin or cotter key.
What is a Cotter Pin?Ī cotter pin is a wedge or pin that is inserted through aligned holes in the components to secure them temporarily. This article explains the cottor pin use, function, and types.
It is usually a metal, short pin with a looped or bent end that look like the letter “C” or a hairpin. The cotter pin is a fastener utilized to temporarily secure two parts together. The cotter pins are most commonly used all over the world.
