Castle nuts from ITA Fasteners come with pre-drilled holes through which cotter pins can be inserted to hold the nuts securely in place. This gives the nuts the ability to withstand constant vibrations and allows them to stay in place during small movements. As these nuts are pre-drilled, they can be used without a pilot hole. These nuts are slotted, allowing it to be installed and removed using screwdrivers. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
