Description
Product Overview
The SUKATC 4 piece threaded ball knob set is engineered to meet the demanding requirements of industrial and hobbyist applications alike. Each knob features a precision‑machined M6 thread that ensures a secure fit on standard M6 screws, while the 35 mm (1‑3/8″) ball‑top diameter provides a comfortable grip for frequent adjustments. Constructed from high‑grade black‑finished metal, the knobs deliver both aesthetic appeal and resistance to wear, making them suitable for environments where durability and a professional appearance are essential.
In addition to the robust threading, the knobs are lightweight yet solid, weighing just 3.84 ounces each and measuring 1.18 × 1.18 × 1.18 inches. This compact size allows for easy integration into tight spaces without sacrificing strength. The black coating not only adds a modern look but also offers protection against corrosion, dust, and moisture, extending the service life of the product even in harsh conditions.
Compatibility is a key advantage of this set. The M6 thread size aligns with a wide range of standard hardware, enabling seamless replacement or upgrade of existing controls. Whether you are retrofitting an older system or building a new assembly, the knobs provide a reliable connection that maintains precise control over mechanical movements.

The smooth rotation and firm grip allow for fine‑tuned adjustments without slipping, ensuring consistent illumination levels and reducing the need for frequent recalibration.
Control levers in machinery and equipment benefit from the ergonomic design of the ball knobs. Operators can quickly modify speed, pressure, or direction settings, improving workflow efficiency and reducing operator fatigue during prolonged use.
