Hexagonal rod wrench with outstanding wear resistance and tolerances exceeding JIS and ISO standards.

By improving machining accuracy, it fits perfectly into the bolt hole, demonstrating excellent wear resistance!

Eight is a manufacturer specializing in high-quality hexagonal wrenches. Our products are all made in Japan and not OEM from overseas. We use our unique steel that combines hardness and toughness, allowing us to produce hexagonal wrenches that are resistant to breaking even under high torque. Additionally, Eight's internal standards are stricter than JIS and ISO standards for both width and diagonal measurements. This machining precision further enhances wear resistance. As a specialized manufacturer, we offer a variety of products, including single-color wrenches, wrenches with auxiliary handles, additional inch sizes, and Torx Plus wrenches. We also have a comprehensive lineup that includes L-shaped, T-shaped, knife-type, and screwdriver-type wrenches. We are able to meet various customer requests, so please take a look and consider our offerings.
