"Anti-loosening bolt" *Achieves significant cost reduction without the need for adhesive*
A new screw, "Motion Tight," with an elastic structure of the thread that prevents loosening just by tightening it normally! It 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 has been adopted in various fields such as artificial satellites, automobiles, motorcycles, robots, wind power generation, and semiconductor manufacturing equipment. Since it does not require adhesives or other anti-loosening products, it achieves significant cost reductions! Additionally, it has excellent functionality that withstands temperature changes. 【Exhibition Information】 ■ First Event Exhibition Name: AXIA EXPO 2026 Date: June 3 - June 5 Venue: Aichi Sky Expo (5-10-1 Centrair, Tokoname City, Aichi Prefecture) Booth Number: E-36 ■ Second Event Exhibition Name: Automotive Technology Exhibition NAGOYA 2026 Date: June 17 - June 19 Venue: Aichi Sky Expo (5-10-1 Centrair, Tokoname City, Aichi Prefecture) Booth Number: 304 *For more details, please contact us via the "Contact Us" button below or feel free to view the materials from the "Download Catalog" button.

Detailed information
-
Motion-tight structural diagram The entire thread exhibits strong spring force, creating a force that tries 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 as the starting point.
-
After the connection: Contact on the plane The axis makes contact with the female thread (nut) on the plane as it extends. As the extended axis tries to return to its original state, a strong anti-loosening force is generated.
-
[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.

February 8 (Wednesday) to 9 (Thursday), 2023" Announcement of Participation in the "12th Next Generation Manufacturing Infrastructure Technology Industry Exhibition - TECH Biz EXPO 2023
Art Screw Co., Ltd. will exhibit at the "12th Next Generation Manufacturing Infrastructure Technology Industry Exhibition - TECH Biz EXPO 2023" held at Fukiage Hall from February 8 (Wednesday) to February 9 (Thursday), 2023. ■Highlights We will showcase a new shape of "Motion Tight" combined with high-strength materials classified as strength category 13.9. By combining high fastening power with strong loosening prevention, we have achieved downsizing of bolts from M12 to M10 and from M10 to M8. This results in more compact components and smaller main products. We can meet various demands such as wanting to reduce the size of bolts or the number of bolts. ■Main Business Targets Manufacturers in the automotive, motorcycle, aerospace, machinery, and tool industries. We sincerely look forward to your visit.
