ART SCREW CO., LTD. 

The most reliable "screw" that eliminates anxiety of 1%.

"Motiontite" is the screw (bolt) that has the entirely new structure with the innovated thread shape to resolve both of the two biggest complaints about the screw, "loosening" and "breakage."
Work is completed by only tightening in a normal way like a normal screw.
We provide innovative technologies achieving reduction in weight and cost.
