Butterfly nut EWN.70-SST-P-M10x20-PO-C4 Z041984

Wing nut – solid mounting with comfort

The EWN.70-SST-P-M10x20-PO-C4 wing nut is a connecting element that combines functionality and ease of use. Designed for precise and quick tightening, it is suitable for both professional and amateur applications. Its construction allows for manual tightening without tools, which significantly speeds up assembly and disassembly.

Material and construction

Made of a technopolymer based on polyamide (PA) reinforced with glass fibers, which guarantees high mechanical strength and resistance to damage. The gray-black color provides a discreet appearance and good visibility in various lighting conditions. The matte surface finish improves comfort and prevents hands from slipping.

• Reinforced polyamide: Provides high resistance to loads and long-term use.
• Glass fibers: Increase the mechanical strength of the nut.
• Chamfered stem end: Protects the clamped surface from damage, even with high tightening torque. This is especially important for delicate materials or where aesthetics matter.
• Available washers: Possibility of using plastic (surface protection) or brass (increased durability) compression washers.

Ease of use and assembly

The ergonomic shape of the wings with slight recesses makes it easy to grip and allows for effective application of force during tightening. This translates to faster and more convenient assembly, as well as reducing the risk of hands slipping. The wing nut is ideal for applications where frequent tightening and loosening are required – e.g. in devices, machines or structures requiring regular adjustment.
