【*Prototype trials now open!】Hard to loosen and hard to break! A bolt that enhances work efficiency while promoting lightweight and energy-saving features.
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 surface, 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, since the screw threads are formed through rolling processing, it is low-cost and high-quality. 【Features】 ■ Powerful 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 lubricating oil ■ Low price, high quality ■ Reusable For more details, please refer to the catalog.
