The new locking nut we propose!
The "SSN (Super Slit Nut)" is a screw that can withstand 1 million vibration tests (NAS test) and exhibits excellent anti-loosening effects. It is equipped with a spring function that generates pre-bolting torque at the top of the nut. There are two springs at the top of the nut with a specific shape, and during tightening, these parts undergo elastic deformation, gripping the threads of the counterpart near the slit area with spring force. This simple structure provides stable anti-loosening effects. 【Features】 ■ Anti-loosening performance that withstands 1 million vibration tests (NAS test) ■ Reusable ■ Prevents dislodgment in environments with intermediate stops or unstable axial forces ■ Can be produced in small lots with short delivery times ■ Adjustable strength of anti-loosening (pre-bolting torque) *For more details, please download the PDF or contact us.
