"Axial force tool to replace existing nuts" - The 'Load Nut' that knows no loosening.
Are you troubled by "nut loosening" caused by vibration devices? No special tools are needed; you can achieve axial force management with just one hand torque wrench! *Patent obtained.
"LOAD NUT" is a "loosening prevention mechanism axial force management nut" that allows for axial force management with just one hand torque wrench, and it does not loosen. (Compatible with large bolts from M16 to M100 and above.) By tightening multiple pressed screws on the nut, high-precision bolt axial force is achieved, and the patented sloped washer prevents loosening. Unlike typical axial force management tools like "bolt tensioners," which experience a 10% to 20% reduction in residual axial force after tightening, this product has absolutely no "residual axial force," and there are no limitations on the thickness of the objects being fastened. Once tightened, it does not loosen remarkably, and conversely, it can be easily loosened when desired. 【Common Issues】 ■ Frequent use of vibrating equipment causes nuts to loosen... ■ Large hydraulic wrenches or tensioners are expensive and difficult to introduce... ■ There is no power source at the work site... ■ The working space is narrow, making it difficult to use standard tensioners... These issues can be resolved with "LOAD NUT"! For more details, please refer to the PDF materials or feel free to contact us.
