Butterfly nut CTD.48 B-M5-2-C2 Z070563

Torque-limiting butterfly nut – precision and protection

The CTD.48 B-M5-2-C2 butterfly nut is a mechanical component designed for applications where controlled tightening torque is crucial. Made of high-quality polyamide-based technopolymer, combined with a steel threaded element and a torque-limiting mechanism, it ensures reliable and safe fastening. This is an ideal solution for both professional installers and end-users who value precision and protection of structural elements.

Design and application

This nut operates on a principle similar to a torque wrench – when a defined tightening torque is reached (2 Nm in this case), the mechanism disengages, signaling with an audible “click” that further tightening is unnecessary. This prevents damage to the fastened elements caused by excessive force. When loosening, the torque limitation does not occur, making disassembly easier. The nut's design allows it to be used in various fixtures and in places where delicate components require special protection against damage.

Advantages of the CTD.48 B-M5-2-C2 nut

• Limited tightening torque: Ensures precise fastening and protects elements from damage caused by excessive force.
• Durable materials: Made of polyamide-based technopolymer and nickel-plated steel guarantees long-lasting and reliable operation.
• Audible signaling: A characteristic “click” sound indicates that the maximum tightening torque has been reached, eliminating the risk of exceeding the permissible value.
• Versatility: Available in black or orange (orange color facilitates identification of the clamping element).
• Easy assembly and disassembly: The mechanism does not limit torque during loosening, making servicing and maintenance easier.
• Precision: Allows repeatable tightening with the same force, which is important in applications requiring high accuracy.

The CTD.48 B-M5-2-C2 nut uses polyamide-based technopolymer for the housing and nickel-plated steel for the threaded element. Its operation is based on a mechanical limitation of the tightening torque to 2 Nm with an M5 thread.

The CTD.48 B-M5-2-C2 nut is an optimal solution for anyone who needs a reliable and precise fastening element, providing protection against damage caused by overtightening. This is a product of Elesa+Ganter – a synonym for quality and innovative solutions in the standard components industry.
