Knurled knobs – precision and functionality in every detail

The B.259/20 B-M6 knurled knob is a standard machine part, valued by professionals for its solid construction and ease of use. Made of high-quality Duroplast, it combines durability and optimal weight. It is an ideal solution for precise control of devices where a firm grip and easy adjustment are important.

Construction and application

The knob is characterized by a knurled surface, which provides excellent grip even in wet or dirty conditions. The brass insert with M6 thread guarantees stable mounting to the shaft or axis. The thread length of 16 mm provides adequate clamping force. The knob diameter is 21 mm, and its total height is 25 mm – these dimensions make it comfortable to use and does not take up much space.

These types of knobs are widely used in:

• Industrial machines and equipment – as control elements for speed, position or force.
• Laboratory equipment – for precise adjustment of experiment parameters.
• Medical equipment – where accuracy and hygiene are required.
• Metalworking - as regulating knobs on lathes, milling machines, etc.
• Industrial furniture - as regulating elements in lifting or rotating mechanisms.

Advantages and benefits

• Durable material: Duroplast is a plastic with high resistance to abrasion, impact and chemicals, which translates to a long service life of the knob.
• Comfortable grip: The knurled surface provides a firm grip even with work gloves, minimizing the risk of slipping during operation.
• Easy installation: The M6 thread and brass insert allow for quick and easy mounting of the knob to various types of shafts and axles.
• Aesthetic appearance: The black color gives the knob an elegant look that blends well with most devices and machines.
• Versatility: The knob will work both in professional applications (workshops, factories) and amateur (DIY).
• Corrosion resistance: Duroplast material is corrosion resistant, allowing the knob to be used in harsh environmental conditions.
• Precise adjustment: Thanks to the knurled surface, it is possible to precisely set the value of the adjusted function.

Thanks to the combination of functionality, durability and aesthetics, the B.259/20 B-M6 knurled knob is a reliable element of equipment in every workshop or industrial device.
