Non-reusable, waiting time for effect is approximately 6~72 hours
In the screw industry, screws have a lower limit value and nuts have an upper limit value. After the screw is tightened, a single-sided friction is formed, creating a tooth gap between the screw and the nut, making it more difficult to maintain the clamping force and causing loosening!
Anti-falling buckle utilizes the huge rebound elasticity of special engineering resin materials to exert a strong anti-loosening effect at the threaded part, turning ordinary screws into permanently strong anti-loosening screws.
After treatment with anti-falling buckle, the threaded part of the screw will have full tooth contact, eliminating any spinning or loosening. It is the world's first successful fully torque-type anti-loosening screw.
Selection of anti-loosening chemical adhesives- Adhesive series
The mixture of adhesive-containing microcapsules is processed at the bolt part to give the bolt itself sealing and locking properties.
Reaction starts when tightening the bolt: MEC processed screws do not react when not in use, but once tightened, the microcapsules rupture, the locking agent oozes out and immediately polymerizes, starting to take effect.
Just combine the screw, locking agent, and sealing agent into one, and it will work well when used directly.
Anti-loosening principle of anaerobic adhesive (such as Loctite 242)
In order to harden anaerobic adhesive, it must "isolate air" and have another condition. That is, it must be in contact with metal, which means that the adhesive cannot harden without metal. This means that anaerobic adhesive is suitable for bonding between metals.
