We would like to introduce our "Titanium Wedge Nut," which combines excellent workability with anti-loosening performance. Unlike anti-loosening nuts with pre-tension torque or those with inserted resin rings, there is no resistance until the nut is seated. Additionally, since there is no damage to the bolt threads, it can be reused repeatedly without degrading performance. 【Features】 ■ Significantly improved workability with free spinning ■ Reusable ■ High anti-loosening performance utilizing wedge-shaped threads ■ Made from high-strength grade 64 titanium material ■ Available sizes in hex flange shape: M6, M8, M10 *For more details, please download the PDF or feel free to contact us.
