Nylon Washer Size: 8 x 30 x 2 mm / 0.31 x 1.18 x 0.08 inch(ODxIDxT). Metal Washer Size: M8. Manual measurement; there may be slight differences. Please refer to the actual product.
- Material - Crafted from phenolic plastic, this ball nut offers good heat resistance, electrical insulation, and durability. The material avoids rusting and reduces overall equipment weight without compromising structural stability, ensuring the ball knob maintains its appearance over time and has a long service life.
- Feature - The ball knob features a bright polished surface that enhances tactile comfort and grip stability, while its spherical ergonomic design conforms to hand contours, reducing strain during extended use. The sturdy knob has a built-in, long-lasting female thread that firmly attaches to machine handles. It also comes with nylon and metal washers to keep it steady and prevent wear over time.
- Easy to Use - Installing these spherical knobs is straightforward. Align the threads with the equipment shaft, hand-twist to secure, and tighten. No special tools are required in most cases. You can quickly and conveniently install them to achieve the desired connection.
- Wide Application - This ball handle is suited for a broad range of equipment, including machine tools, lathes, drill presses, and control panels. It integrates seamlessly with gear levers, pull rods, and valve handles on devices from CNC systems and woodworking machinery to automotive components, exercise equipment, and jigs or fixtures.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
