ロックファスナー Company Profile

The lock fastener is the only nylon nut manufacturing company in Japan that has received direct technical support from the U.S. company Esna.

Since its establishment in 1966, Rock Fastener has been pursuing the goal of being a company that is needed by our customers through the manufacturing of our main products, the locking nuts and special nuts, and before we knew it, we have surpassed half a century. Now, our products are utilized in various fields, from everyday living spaces to energy and transportation. In order to continue being a company that is needed by our customers in the future, there is nothing more important than "further improving quality." Of course, quality is not just about enhancing the precision of our products. It is equally important to respond flexibly and promptly to all customer requests. On the other hand, we believe that valuing our employees is also a significant mission of Rock Fastener. To achieve this, we will continuously review and improve our workplace environment. The notion that manufacturing sites can be dirty is a thing of the past; we are confident that improving this work environment will also lead to a further enhancement of quality. Rock Fastener will continue to be a company that is needed by our customers in the future. To that end, we will not shy away from any challenges. Please look forward to our future endeavors.
