Pins

Spring Pins

Spring pins are hollow, cylindrical fasteners with a slotted or coiled design that compress upon insertion to exert continuous radial tension against the hole walls. Their inherent elasticity allows them to absorb impact loads and accommodate wider manufacturing tolerances than rigid solid pins. These self-retaining fasteners are widely used for securing gears to shafts, forming hinge pivots, and aligning assemblies in heavy machinery and automotive applications.
