Internal snap rings are circular fasteners used to secure components within a housing or bore. They fit into a groove on the inside of a shaft or housing, preventing parts from moving out of place. These rings are commonly made from spring steel, which allows them to maintain tension and resist deformation. These fasteners are essential in various applications, including automotive assemblies and industrial machinery. Internal snap rings come in different sizes and thicknesses, making them versatile for securing bearings, gears, and other components. Their design allows for easy installation and removal, contributing to efficient assembly and maintenance processes.
