Achieve weight reduction with bolt downsizing! Introducing the new screw 'Motion Tight', which is resistant to contamination and strong against temperature changes.
The "Motion Tight" developed by Art Screw is a "looseness prevention bolt" that solves the problem of loosening bolts and screws. It achieves downsizing with high axial force and fatigue strength, and since it does not require a locking mechanism, it contributes to the "lightweight" of bolts and screws, leading to cost reduction! Additionally, it has excellent functionality that withstands temperature changes. [Conditions for Enabling Bolt Downsizing] ◆ Must not loosen ◆ Must maintain high axial force ⇒ Motion Tight meets these conditions! [Benefits of Adopting Motion Tight] ■ Weight reduction through bolt downsizing ⇒ Half the cost of bolts + no need for locking mechanism = significant reduction in material costs ■ Shortening the engagement length of screws allows for thinner and lighter fastening components ⇒ Lightweight components + cost reduction ■ Standardizing bolts to the same size ⇒ Significant improvement in work efficiency = expected increase in factory profits *For more details, please contact us directly using the "Contact Us" button below.

Detailed information
-
Motion tight structure diagram The entire thread profile exerts a strong spring force, working to return to the seat side.
-
Before the conclusion: Contact from the summit. The axis of the bolt is drawn out and extended from the summit.
-
After the connection: Contact on the plane The axis makes contact with the female thread (nut) on the plane as it extends. The extended axis generates a strong anti-loosening force as it tries to return to its original state.
-
[Regarding Stress Concentration] - General screws have stress concentration at 3 threads. - MotionTite distributes stress across all threads. - Fatigue strength is improved, making it more resistant to delayed failure.
