Strong against vibrations, reusable! Anti-loosening! 'E-LOCK Nut'

Strong against vibrations, reusable! Anti-loosening! 'E-LOCK Nut'

The three-blade design provides stable anti-loosening effects! Thanks to the high-strength friction ring, it can be reused multiple times! [Manufactured by Osaka Forming Co., Ltd.]

The "E-LOCK Nut" handled by Daiichi Industry features a three-blade design that enhances its anti-loosening function and possesses the strength to withstand repeated use. In the case of conventional two-blade products, one blade gets lodged in the thread valley, effectively resulting in a state of anti-loosening with only "one blade," leading to concerns about stability. However, this product's three-blade design effectively increases thread stability with "two blades." Additionally, durability tests under vibration showed no deformation in the three friction rings of this product, proving its ability to withstand repeated use due to the sustained effect of the springs. (Other manufacturers' nuts with high anti-loosening functions may experience deformation.) **Features** 1) The three-blade design provides a more stable anti-loosening effect compared to conventional products. 2) Prevents early detachment even if the tightening axial force decreases. 3) Strong and capable of withstanding repeated use. ★ This product is from Osaka Forming Co., Ltd.
