Wing nut CTD.48 B-M5-3-C9 Z070566

Torque-limiting butterfly nut

The CTD.48 B-M5-3-C9 butterfly nut is a fastening element designed for precise tightening and protection of sensitive components. Its construction, based on a torque-limiting mechanism, makes it ideal for applications where excessive force could damage the mounted elements. This solution is particularly appreciated in tooling and devices requiring delicate assembly.

Construction and application

The nut is made of durable polyamide-based technopolymer, which ensures its resistance to mechanical damage and corrosion. The threaded element and torque-limiting mechanism are made of nickel-plated steel – guaranteeing durability and reliable operation. Available in black and orange (facilitating identification of the clamping element), the CTD.48 B-M5-3-C9 nut offers flexibility in terms of mounting and integration with various structures.

The nut's operating mechanism is similar to that of a torque wrench – when the set torque value (3 Nm in this case) is reached, a characteristic “click” occurs, signaling the need to stop tightening. It is worth remembering that there is no torque limitation when loosening. This design allows for safe and repeatable fastening of elements, minimizing the risk of damage.

Advantages and benefits

• Protection against damage: Torque limitation protects delicate components from overload and damage during assembly.
• Precision: The “click” mechanism ensures accurate and repeatable tightening with a set amount of force.
• Durability: Made of high-quality materials (polyamide and nickel-plated steel) guarantees a long service life of the nut even in demanding working conditions.
• Versatility: Availability in two colors (black and orange) and with an internal thread makes it easy to adapt to different applications.
• Easy identification: The orange color allows for quick identification of the clamping element in complex structures.
• Application in precision devices: Ideal for tooling, machines and devices where torque control is crucial for proper operation.
