[About Strength Classification] Loosening Prevention Bolt "Motion Tight"
【※Prototype trials now recruiting!】Strength grades correspond to 8.8, 10.9, and 12.9! "Motion Tight" bolts that are resistant to loosening and breaking.
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 side, providing strong rebound force and high loosening prevention capability. 【Strength Classification of Motion Tight】 ■8.8 ■10.9 ■12.9 For more details, please contact us directly.
