The term 'Belt Parts' can refer to a variety of components that make up a belt, such as BUCKLES. A buckle is a fastening device used to hold two ends of a belt together. It typically consists of a metal frame with a hinged catch and a prong or hook that fits into a loop or hole on the other end of the belt. BUCKLES are commonly used in clothing, shoes, and accessories, as well as in military and law enforcement equipment.
