Wing nut CTD.48 B-M5-3-C2 Z070565

Torque-limited butterfly nut – precision and protection

The CTD.48 B-M5-3-C2 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 element and a torque-limiting mechanism, it provides reliable and safe fastening. This is an ideal solution where excessive force could damage the mounted components.

Design and application

This nut operates on a principle similar to a torque wrench – when the set tightening torque (3 Nm in this case) is reached, a characteristic “click” occurs, signaling the need to stop tightening. This mechanism protects components from overload, which is particularly important in precision devices and equipment. When loosening, there is no torque limitation, which facilitates disassembly.

CTD butterfly nuts find applications in many industries, including:

• in tooling, where precise mounting of elements is required;
• in devices where delicate components may be damaged by overtightening;
• in applications requiring easy and quick assembly and disassembly without tools.

Advantages of the CTD.48 B-M5-3-C2 nut

• Limited tightening torque: Ensures protection against damage to mounted elements thanks to precise limitation of the tightening force to 3 Nm.
• Durable materials: Made of polyamide-based technopolymer and nickel-plated steel guarantees long-lasting and reliable operation.
• Convenient installation: The butterfly design allows for quick and intuitive assembly and disassembly without the use of additional tools – saving time during installation and service.
• Audible signal: A characteristic “click” informs about reaching the maximum tightening torque, eliminating the risk of exceeding the permissible value.
• Aesthetic appearance: Available in black or orange (orange facilitates identification of the clamping element).
• Versatility: Available with an internal thread (M5), allowing it to be adapted to various applications.
