Knob REG.MOMENT MZD.50-A-M8 Z071233

Product features

• Adjustable tightening torque for precise fastening

The MZD.50-A-M8 knob is part of a series of knobs with adjustable tightening force, designed for applications requiring precise control of clamping force. Thanks to its unique spring mechanism (ELESA patent), it allows setting the torque in the range of 0.2 Nm to 1 Nm, minimizing the risk of damage to threads or delicate components. This solution is ideal for both professional installers and end-users who need a reliable and safe way to fasten.

Design and application

The knob is made of polyamide (PA), which ensures strength and resistance to mechanical damage. The thread length is 15 mm, and the diameter is 47 mm. The metric thread size is M8. The design with a threaded sleeve facilitates assembly and provides a stable connection. The spring mechanism works similarly to a torque wrench – when the set torque is reached, a characteristic “click” occurs, signaling the need to stop tightening. This solution is particularly useful in applications where excessive force could damage the fastened components, e.g., when working with glass or plastics.

Advantages and benefits

• Torque adjustment: The ability to smoothly adjust the tightening torque in the range of 0.2 - 1 Nm allows adapting the clamping force to specific application needs.
• Protection against damage: The disengaging mechanism protects threads and delicate components from damage caused by overtightening.
• Durability: Tests confirm the high durability of the mechanism – after 60,000 cycles, the tightening torque remains unchanged.
• Versatility: The knob finds application in various applications, from fastening elements in tooling to protecting against damage during glass processing or assembly of machines with plastic threads.
• Ease of use: Quick and easy reading of the set torque thanks to the scale under the cover of the socket head cap screw with a hexagonal socket.
• Cost-effectiveness: Compared to other knobs with limited tightening force available on the market, the MZD model offers an attractive price while maintaining high functionality.
