Cotter Pins


Cotter pins from ITA Fasteners are fragile pins used for precision applications in masonry jobs. These pins are used to secure an already fastened system. They are first bent into the perfect shape to be used with other fasteners. They are one of the very few wire-formed fasteners which can be used externally in equipment building or home constructions. Due to their ductility, they are versatile as they can be used along with several fasteners. Their low cost and high versatility have made it one of the favourite fasteners used by masons around the world.

These pins, also known as split cotter pins, are self-locking and can be installed quickly without using any special equipment. In addition to that, the pins can be removed quickly and can be reused in other applications. This will ultimately lead to saving money and time for yourself. There are several types of split pins for you to choose from, depending on the specifications of your project. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
