The E-LOCK series bearing stop nut type does not require washers or keyway machining and can be installed as is. The friction ring incorporated into the top surface of the nut contacts the threads of the bolt, applying strong pressure through spring action stress and reaction force, preventing loosening and free rotation. Torque management is easy, and installation is simple. A wide range of sizes is available! **Features** - No keyway machining required for the shaft - Reduction of machining costs possible - No need for a washer, minimizing bending errors - Effective in preventing loosening due to vibrations - NETIS registration number: KK-180059-A *For more details, please refer to the catalog. Feel free to contact us with any inquiries.*

The "High-Performance Lock Nut SMART NUT" is designed to provide a more straightforward, more effective, and more stable locking function, ensuring greater safety and reliability, as well as enhanced anti-loosening effects, while also emphasizing usability. The spiral shape of the three-blade friction ring (special spring) achieves stable anti-loosening performance and prevents early detachment even when axial force decreases. Additionally, by incorporating a countersink on the seating surface, it reduces stress concentration on various parts of the bolt during tightening, preventing bolt breakage accidents. *For more details, please download the PDF or contact us. -------------------------------------------------------- The unit price may vary depending on the purchase quantity, and larger lot sizes may result in lower unit prices.
