A screw that won't loosen! It's a bolt that won't come off the nut!
The "locking bolt" is a product of Iijima Manufacturing Co., Ltd., which manufactures parts for metal machinery and machine tools, as well as jigs. It is a screw that can be used multiple times without loosening. (It is a bolt that does not allow the nut to come off.) 【Features】 ■ Does not loosen ■ Patent Certificate No. 5712408 *For more details, please contact us.
The bolt alone has a high anti-loosening effect! The special valley-shaped design demonstrates a wedging effect, providing a solid lock.
The "Wedge Lock Bolt" features an asymmetric thread profile in the valley and utilizes a wedge surface to provide a powerful anti-loosening effect. It prevents loosening simply by tightening. It can be reused by reducing the adhesive application process. Additionally, it allows for anti-loosening in blind hole environments where nuts cannot be used. 【Features】 ■ Reduction of adhesive ■ High anti-loosening performance - Junker: Residual axial force of over 80% - NAS method: 17 minutes of durability (3000 cycles) ■ Usable in blind holes *For more details, please refer to the PDF document or feel free to contact us.
