Custom Slotted Toothed Spring Pin Manufacturer & OEM Fastening Supplier
Slotted tooth spring pins feature a split cylindrical body with formed teeth along the slot. During installation, the pin compresses inside the hole and generates radial pressure against the hole wall, while the toothed profile provides additional resistance to rotation and axial movement. This structure is used for component retention, shaft fastening, hinge connections and mechanically locked joints.
As a China toothed spring pin manufacturer and factory, we produce standard and custom slotted toothed spring pins according to customer drawings, samples and specified requirements. Pin diameter, length, tooth profile, slot geometry, wall thickness, material, hardness and surface finish can be defined according to the required hole fit and retention characteristics.
