Butterfly nut CTD.48 B-M5-2-C9 Z070564

Torque-limiting butterfly nut – precision and protection

The CTD.48 B-M5-2-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 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 or affect their proper operation.

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" the need to stop tightening. This design allows for repeatable and precise fastening of elements, eliminating the risk of damage. It is important to remember that the torque limitation does not apply when loosening.

CTD butterfly nuts find applications in many industries, including:

• precision tooling, where delicate and controlled fastening of elements is required;

• electronic and mechanical devices, where excessive force could damage sensitive components;

• production machines and equipment, where fastening precision affects the quality of operations.

Advantages of the CTD.48 B-M5-2-C9 nut

• Protection against damage: The torque-limiting mechanism protects components from overload and damage.

• Precision: Provides repeatable and controlled fastening with a torque of 2 Nm.

• High-quality materials: Made of durable technopolymer and nickel-plated steel, guaranteeing long-lasting and reliable operation.

• Easy installation: The nut design allows for quick and convenient assembly and disassembly.

• Distinctive color: Available in black or orange – the orange version makes it easier to identify the clamping element.
