Du-Bro 4-40 Swivel Ball Link (12 Pack)

4-40 Swivel Ball Link (12 Pack) from Du-Bro - DUB861

The DU-BRO Swivel Ball Link is a high-quality control linkage designed to give your RC aircraft smoother and more accurate control movement. If you want a linkage that operates cleanly, reduces friction, and stays reliable over time, this swivel ball link is an excellent choice for many different types of models. Each link features a burnished, nickel-plated brass swivel ball. This ball rotates freely inside its socket, allowing your control rod to move smoothly in any direction. The nickel plating helps the ball resist wear and corrosion, so it continues to perform well even after many flights. This design helps reduce binding and slop—two common issues that can affect how your aircraft responds in the air.

The DU-BRO Swivel Ball Link comes as a complete assembly, including:
A socket head cap screw
A brass shim
A hex nut

These parts work together to create a strong, secure, and easy-to-install connection. The brass shim improves alignment and smooth movement, while the cap screw and hex nut hold everything tightly in place. Despite its strength and durability, each assembly weighs only 2 grams, keeping your aircraft light and responsive. This swivel ball link is a great upgrade for elevators, rudders, ailerons, throttle linkages, or any control surface that needs clean and accurate motion. It is also ideal for builders who want long-lasting hardware they can count on.

Proudly Made in the USA, the DU-BRO Swivel Ball Link delivers smooth operation, dependable performance, and the quality engineering RC pilots trust.
