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.

【Patent Numbers】 ■Patent No. 4806103 ■Patent No. 4878407 【Evaluation Tests】 ■NAS Vibration Test → Cleared a vibration test with a total of 30,000 rotations in 17 minutes ■Yunker Vibration Test → Comparison data with standard products available on the official website ■Fatigue Test: JISB1081 → Approximately 20% improvement ■Load Distribution Ratio (%) 　　　 Standard Bolt: Motion Tight Thread No. 1 32.9:26.4 Thread No. 2 19.7:19.6 Thread No. 3 14.1:15.6 Thread No. 4 11.5:13.4 Thread No. 5 10.4:12.2 Thread No. 6 11.4:12.8 　Total 　　 100.0:100.0 *Motion Tight has a more averaged load distribution ratio compared to standard products, resulting in higher fatigue strength and reduced likelihood of breakage. ■Torque and Axial Force Test → Variability of axial force is about half that of standard products.
