UJEN Indexing Pins (Spring Pull Pins) offer an ideal solution for rapid fastening and frequent repositioning of components. Simply pull the top knob to release the pin from the positioning hole, adjust the component to your desired location, and release—built-in spring action instantly re-engages the pin for precise positioning.

Additionally, UJEN indexing pins feature an ergonomic knob design, allowing you to easily tighten the screw manually, securely clamping the component and eliminating vibration or movement, widely used across fitness equipment, industrial machinery, medical devices, and furniture hardware industries.
