Butterfly nut CTD.48 P-M5x16-3-C2 Z070577

Torque-limited butterfly nut

The CTD.48 P-M5x16-3-C2 butterfly nut is a fastening element designed for precise tightening and protection of sensitive components. Made of high-quality polyamide-based technopolymer in combination with a steel threaded pin, it ensures durability and reliable operation. Its construction is based on a mechanism that limits the torque, functioning like a torque wrench – when the set value (3 Nm in this case) is reached, a characteristic "click" occurs, signaling the end of tightening.

Application and benefits

This nut is particularly useful in situations where excessive tightening force could damage the mounted elements. Therefore, it finds application in various types of tooling, as well as in devices requiring delicate assembly. The torque-limiting mechanism minimizes the risk of damage and ensures repeatability of the tightening process. Importantly, there is no torque limitation during loosening, which facilitates disassembly.

• Protection against damage: The torque-limiting mechanism protects components from overload and potential damage.
• Precision: Ensures repeatable and controlled tightening process, eliminating the risk of errors.
• Durability: Made of high-quality materials guarantees long life and resistance to working conditions.
• Ease of use: A characteristic "click" informs about reaching the correct tightening torque, making it easier for the installer to work.
• Versatility: Available in black and orange (allowing easy identification of the clamping element).

Construction and assembly

The CTD.48 P-M5x16-3-C2 nut has an M5 thread with a length of 16 mm. It is made of polyamide-based technopolymer, which provides good chemical and mechanical resistance. The steel threaded pin is nickel-plated to increase corrosion resistance. Assembly is simple and intuitive – the nut is screwed onto the threaded fastening element until a characteristic "click" is heard. This solution will be appreciated by both professional installers and people who assemble devices themselves.
