They may be used to replace nuts, threaded sleeves, cotter pin, rivets, set collars, machined shoulders and many bulkier and more expensive fastening devices. As circlips are installed in pre-cut grooves, these pre-cut grooves can often be machined simultaneously with other production process; they eliminate threading, tapping, drilling, and other costly machining operations. Speed of assembly and disassembly further reduces manufacturing costs. Space saving, compared to contemporary methods. Reduces assembly weight. Longer service life. All sizes available as per Standard.
