Butterfly nut EWN.55 P-M8x20-C4 Z016667

Wing nuts – quick assembly and ergonomics

The EWN.55 P-M8x20-C4 wing nut is a component from the family of standard machine parts, designed with convenience and assembly efficiency in mind. It is characterized by an ergonomic wing shape, allowing for quick tightening and loosening by hand, without the need for tools. This is an ideal solution for both professionals working on an assembly line and end-users assembling furniture or devices themselves.

Wing nuts of this type are widely used in machine and device structures where frequent disassembly of components is required. Made of technopolymer, they are resistant to corrosion and mechanical damage, guaranteeing long-term reliability. This material also provides good electrical insulation, which may be important in some applications.

Design and application

The EWN.55 P-M8x20-C4 nut has a metric M8 thread with a length of 20 mm, ensuring compatibility with a wide range of screws and threaded rods. The wings of the nut facilitate grip and precise adjustment of the tightening force. This makes it possible to obtain an optimal connection without the risk of damaging the fastened elements. The wide range of applications includes:

• Assembly of machine and device housings
• Furniture structures requiring frequent disassembly
• Laboratory and measuring equipment
• Applications in the food industry (due to the hygienic material)
• Fastening elements in profile systems

Advantages of wing nuts

• Quick assembly: No need for tools significantly speeds up the assembly and disassembly process.
• Ergonomics: The comfortable shape of the wings provides a secure grip and minimizes effort during tightening.
• Corrosion resistance: The technopolymer material is resistant to moisture and chemicals.
• Versatility: Compatibility with M8 thread allows the nut to be used in many different applications.
• Aesthetics: The aesthetic appearance of the nut improves the visual values of the assembled structures.
