Simultaneously solve rotational loosening due to vibration and non-rotational loosening caused by metal settling and relaxation!
The two most important issues in bolt fastening are rotation loosening due to vibration and non-rotation loosening caused by metal settling or relaxation. 【Rotation loosening... causes spontaneous loosening rotation.】 ● Vibration ● Variable load Vibration and variable loads continuously apply external pressure to the fastened bolt, eventually causing the bolt to rotate back and reducing the axial force. 【Non-rotation loosening... causes a decrease in fastening force without triggering back rotation.】 ● Settling of metals and other materials Within the first few hours of fastening the bolt, the materials come into contact and exert pressure on each other. The surface irregularities that typically exist in any material settle against each other, leading to a decrease in axial force. ● Relaxation of the joined materials Certain materials, such as soft metals or composite polymers, may lose their resistance over time after being fastened, resulting in a decrease in axial force. Nord-Lock X-series washers solve both of these issues simultaneously!

Company information
Since our founding in 1927, we have gained the trust of many people through the manufacturing and sales of machine tools, screws, and industrial machinery and equipment. Additionally, since being appointed as a member of the JIS standard committee for hexagon socket screws, steel taper pins, and oilers by the Industrial Technology Institute in 1955, we have been dedicated to the development of the industrial sector for over 50 years. Currently, we are focusing on the manufacturing and sales of machine tools, precision cutting tools, and high-quality screws, which have been our core business since our inception. We are also expanding our global product offerings with the manufacturing and sales of OSG cutting tools, Ambraco products from the U.S. SPS company, and JST-branded industrial machinery and equipment, thereby establishing a solid position in the industry. As the 21st century becomes increasingly complex and diverse, we aim to continue our efforts based on our fundamental principle of "prudent management" since our founding, in order to be of service to everyone.
