Sturdy spring tension ensures that the T-handle pin remains firmly in place. Screws and knobs dominate many production lines, yet a UJEN T-type pull offers an upgrade: a comfortable T-handle with seven color disc options for visual impact. Opt for oyster shell or wood fiber to minimize plastic use, backed by Taiwan CNC and mold precision. Ergonomic details lower strain under frequent locking. ISO9001-certified production addresses bulk or custom orders swiftly, fitting B2B settings from medical and sports to automotive, aerospace, and semiconductors.
Function
UJEN T-Handle Spring Pull Pins are designed for rapid fastening and frequent repositioning of components. Simply pull the T-shaped handle to quickly disengage the pin from the component's hole. After adjusting to your desired position, release the handle—built-in spring action instantly re-engages the pin for precise and secure positioning.
Additionally, these T-Handle Spring Pull Pins feature a threaded locking design, allowing pre-tightening with a wrench to enhance the stability and precision of the fixed components. Ideal for use in industrial machinery, fitness equipment, medical devices, furniture hardware, and more.
