ボルトワン Company Profile

What Bolt One aims for is to exceed customer expectations.

Bolt One Co., Ltd. has been a large hot-forged bolt manufacturer since its establishment in 1968, contributing significantly to the development of the construction, civil engineering, and machinery industries in Japan. In recent years, we have expanded our scope of activity into fields that require higher performance and reliability, such as nuclear power plants and large cranes. While we continue to insist on high quality as a machinery parts manufacturer, we have also focused on the development of new technologies, successfully mass-producing the world's first 10.9 high-strength hexagon socket bolts in a 33mm size through cold forging in 2006. Furthermore, we view not only our products but also the entire process from manufacturing to project completion for the end user as part of our offering. We aim to achieve the industry's shortest manufacturing lead times and provide inspection documents free of charge, establishing a trusted brand as an innovative company at the forefront of the industry.
