DUBRO DURA COLLARS 1/8" BULK 12

The DU-BRO Nickel Plated Shaft / Wheel Collars are precision-machined, high-quality brass collars designed to provide a secure, reliable hold on wire landing gear, axle shafts, control systems, and many other RC applications. Each collar is nickel plated for long-lasting durability, corrosion resistance, and a clean, professional appearance on your aircraft, car, boat, or robotics project.

DU-BRO designs these collars with enough material around the threads to prevent stripping, even after repeated tightening or adjustments. This makes them extremely dependable for landing gear retention, wheel positioning, pushrod stops, and hundreds of custom uses across the hobby and engineering world. Each collar includes a matching set screw, and most sizes also include an Allen wrench for quick and easy installation. (Wrench not included with sizes #243 & #244.)

These collars are available in a wide range of inside diameters (1/16" to 1/4") so you can choose the perfect fit for your landing gear wire or axle. The consistent machining ensures smooth operation, tight clamping force, and vibration-resistant performance.
