Enhance safety and make maintenance easier! As a non-loosening nut, it is useful in various situations.
The "Tentacle Nut" is a product developed based on years of screw research, which elucidates the causes of nut loosening. It can be mounted on standard market bolts, achieving a bolt + nut combination that does not loosen with just the replacement of the nut. Results from loosening tests and analyses have proven that there is no self-loosening. 【Features】 ■ The axes of the bolt and nut are perfectly aligned, taking the bolt into consideration. ■ Torque and tension management can be achieved with the lower nut. ■ It can be easily removed when rotated in reverse order from the upper nut to the lower nut. ■ It does not damage the seating surface, just like a standard nut. *For more details, please refer to the PDF materials or feel free to contact us.
