Due to the high strength of the nut, it can be used with bolts of strength grades 8.8, 10.9, and 12.9.
By filling the gap between the male and female threads over 360 degrees, the prevention of loosening is ensured against any vibrations.

Applications/Examples of results
The Flex Lock Nut is a high-quality locking nut developed by SPS Technologies in the United States for aerospace applications. It is now widely adopted across various industries, from general manufacturing to aviation, earning immense trust from users. In our country, it is also extensively used in general industrial machinery, semiconductor manufacturing equipment, various engines, and nuclear power plants. The Flex Lock Nut features an all-metal integrated structure where the locking mechanism and the nut are combined, making it a resistance torque type locking nut (All Metal Torque Self-Locking Nuts). The standard version is non-heat-treated; however, due to its longer engagement length compared to conventional products, it possesses mechanical properties equivalent to ISO Class 8, and it has been confirmed that it far exceeds the guaranteed load of Class 12 nuts in strength tests. Therefore, it satisfies the high strength conditions necessary to generate sufficient preload, which is fundamental to preventing screw loosening.

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.
