[About the Material] Loosening Prevention Bolt "Motion Tight"

【*Prototype trials now open!】 Materials compatible include stainless steel and iron (plated, blackened, etc.)! "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 side, providing strong rebound force and high loosening prevention capability. 【Materials of Motion Tight】 ■ Stainless steel ■ Iron (plated, blackened) Various materials and surface treatments are available as per your request.
