Wing nut CTD.48 P-M6x25-3-C9 Z070586

Torque-limiting butterfly nut – precision and protection

The CTD.48 P-M6x25-3-C9 butterfly nut is part of the CTD family, designed for applications where controlled tightening torque is crucial. Made of high-quality polyamide-based technopolymer, combined with a steel threaded pin, it ensures durability and reliability. This is an ideal solution for installers and users who want to avoid damage to fastened elements due to excessive force.

Design and application

This nut works on the principle of a disengaging mechanism, similar to a torque wrench. Once the set tightening torque is reached (3 Nm in this case), a characteristic “click” occurs, signaling the end of the process. This allows for precise fastening of elements without the risk of damage. The mechanism is unidirectional – there is no torque limitation during loosening.

CTD nuts are used in many industries, especially where protection of delicate components is required:

• in precision tooling,
• in electronic devices,
• in machines and equipment where overtightening can lead to failure.

Because the nut is available in black and orange, it is easy to distinguish the clamping element from the other parts of the structure. The version with a threaded pin (stud) facilitates assembly and disassembly.
