Company Mission

“Screw” has a history of more than 2,000 years and the most widespread industrial product in the world.
Screws as a fastening material must depend on frictional force, therefore to solve loosening issues is an eternal theme, and it is still the cause of many accidents resulting in loss of human life.
NejiLaw inc. was born with the mission to solve the unprecedented problem with the creation of screws that never loosen, and to contribute to solving the problems of all kinds of things/products, industries, and companies in the world that are related to the tangible object of "Screw" and to open up new connections with the numerous social issues and various technological problems lying in the world, thereby we can solve a wider range of problems with our inventions as the driving force.

To contribute to the construction of a more prosperous, advanced, safe, secure, progressive, and sustainable society by solving the world's unsolved issues via problem-solving inventions, our mission is constantly to bring new value to the world with new value-creating inventions, being rooted in the providence of nature and based on science and technology.
