Loosening Prevention Bolt "Motion Tight" [*Prototype Trials Now Open!]
Reusable! The bolt 'Motion Tight' that can eliminate loosening and breakage. Patented in 11 countries worldwide with a unique structure! [Currently recruiting for prototype trials]
The "Motion Tight" handled by Art Screw is a revolutionary bolt that eliminates the two major complaints in screw fastening: "loosening and breakage of screws." The screw threads are slightly inclined on the seating side, providing strong rebound force and high loosening prevention capability. Additionally, the stress dispersion effect in the screw valleys enhances fatigue strength, making it resistant to delayed breakage. Furthermore, the threads are formed through rolling processing, ensuring low cost and high quality. 【Features】 ■ Strong loosening prevention capability with the bolt alone ■ Fatigue strength 1.2 to 1.3 times higher, with the same workability as standard bolts ■ Stable axial force even without lubrication ■ Low price, high quality ■ Reusable *If you wish to request a prototype trial, please contact us with "Prototype Request" clearly stated. *For more details on Motion Tight, please refer to the catalog or technical documents.
