Winged Fastening Pull Pin, Winged locking Indexing Plunger, D31 D35 D39 D44 D49 | UJEN DEVELOPMENT CO., LTD.
The wing pull pin, also known as the dual-wing fastening pin, is engineered for enhanced grip efficiency and structural stability. Compared to traditional round pull pins, its dual-wing design improves directional force and provides a 30% increase in fastening strength—making it ideal for high-frequency manual adjustments where ease and reliability are essential. Typical applications include medical carts, foldable structures, AV mounts, and industrial rails.
UJEN has optimized the wing shape with smooth curves for superior ergonomics and visual refinement. The main body is constructed from PA6 + glass fiber composite for high mechanical strength and long-term durability. The matte surface finish is comfortable to touch and easy to grip. The internal spring mechanism enables consistent, smooth operation without sticking. The default metal shaft uses carbon steel with trivalent zinc plating, and we also offer stainless steel (SUS304), alloy steel, or tool steel options based on your strength requirements.
Multiple stroke lengths, thread sizes, and custom head or body finishes are available. You may also personalize the color, surface treatment, or logo to align with your product design. This component is ideal for hidden mechanisms, unified aesthetics, or assembly-driven applications—offering a smart balance of performance and design detail.
