Both types offer a number of advantages over other fastening methods.
– Their cost is relatively low when compared with other types of fasteners.
– Their use often results in savings in raw materials and simplified machining operations for other parts in the
assembly.
– One circlip often can replace two or more parts.
– Assembly toolings developed for circlips usually permit very rapid assembly of the fasteners, even by unskilled
workers.
Material: Circlips are manufactured from spring steel with high tensile and yield strength.
