コーエーテック Company Profile

The value that surpasses the bolt.

Koei Tech Co., Ltd. has been contributing to a wide range of manufacturing, primarily for major automobile manufacturers and machine tool manufacturers, through the production of specialized bolts that require advanced technology, such as union bolts and plug bolts, since its establishment in 1970. With facilities that boast one of the largest scales in the prefecture, we perform "cutting, grinding, and rolling" in an integrated manner, enabling meticulous manufacturing management at each stage until completion, thus achieving a high-precision and low-cost mass production system. We take pride in having supported product development with functionalities that go beyond mere bolts, as well as providing added value such as improved functionality and cost reduction, which we believe has been well received. Please feel free to contact us with any inquiries. We will consolidate the knowledge and know-how we have cultivated to offer high-quality, high-function products and new proposals that will bring new value to your business.
