What is r-clips?

R-clips, also known as hairpin cotter pins or hitch pin clips, are small, U-shaped wire clips that are used to secure a pin or bolt in place. They have a loop on one end and two straight legs on the other, which are bent back to hook onto the pin or bolt. The R-shape of the clip provides resistance and prevents it from coming out on its own, making it a reliable locking mechanism. R-clips are commonly used in applications such as automotive, agriculture, and machinery industries. They come in various sizes and materials, including stainless steel, zinc-plated steel, and brass.
