Material and construction

Made of a technopolymer based on polyamide (PA) reinforced with glass fibers, it provides high resistance to mechanical damage and external factors. The gray-black color and matte finish give it an aesthetic appearance. The chamfered end of the stud minimizes the risk of damage to the clamped surface even with high tightening torque. Versions with a clamping pad made of plastic or brass are also available – this option allows you to adapt the nut to specific application requirements, increasing the durability of the clamping surface or providing additional protection for delicate materials.

Ease of use and installation

Light recesses at the ends of the wings make it easier to grip and allow for effective use of force during tightening. This makes working with the nut comfortable even in difficult conditions. The butterfly nut EWN.55 SST-P-M8x20-C3 is easy to install and disassemble, which translates into time savings during servicing or modification of devices.
