We manufacture "Active X" anti-loosening bolts, nuts and washers which deliver stable unloosening tightness due to the unique configuration. "Active X" has the characteristic skirt-shaped internal space extended, and we developed a fastening member that produces a high unloosening effect. Our products are used in vehicles, bridges, airplanes, ships and other vibratory objects.

Message from President
Tadayoshi Yamazaki

The fatal accident 10 years ago caused by a detached truck tire triggered our research on vibration absorption. A suction cup in a bathroom gave us a hint of shaping like a skirt. Our research for many years resulted in the development of catenary type fastening member that produces a high anti-loosening effect. We are determined to make efforts to enter into and contribute to the screw industry where safety, security and high quality are always demanded while, improving our technical capabilities. We will also advance into overseas markets.
