YAMAZAKI ACTIVE Co.,Ltd
“Active X” with an ideal shape that has excellent power to absorb vibration and impact.
We manufacture "Active X" anti-loosening bolts, nuts and washers which deliver stable unloosening tightness due to the unique configuration. "Active X" has the characteristic skirt-shaped internal space extended, and we developed a fastening member that produces a high unloosening effect. Our products are used in vehicles, bridges, airplanes, ships and other vibratory objects.
[Product description] The catenary structure of Active X absorbs vibrations and impacts with elastic deformation. It has a simple structure with only one component that enables easy torque management and retightening. You can use it any number of times. "Active X nut/bolt" and "Active X washer", developed by collaboration of industry, academia and government, including Faculty of Engineering at Shinshu University and Nagano Prefecture General Industrial Technology Center, have superior anti-loosening effects that greatly enhance safety to help your operation. We appreciate your trial use and consideration. [Market share/Ranking] Acquired Patent No. 4975879. Bolt = Design Registration No.1439822 and 1439959.

[Company strength] We develop, manufacture and sell "Active X" anti-loosening bolts, nuts and washers which are used in vehicles, bridges, airplanes and ships. We tailor our bolts to your needs; M30 or larger bolts (our forte is in larger sizes) custom-made bolts etc. We take orders for one piece up. We accept urgent orders of special specifications. We are ready to deliver products immediately by using the system of Sunco Industries Co., Ltd. [Business description] Integrated production from raw materials to finished products of construction machine parts, hydraulic valves and spools. Development, manufacturing and sales of "Active X" anti-loosening bolts, nuts and washers . Custom-made bolts are also available. [Industry] Manufacturing [Strength of products/technologies] Our "Active X" anti-loosening bolts, nuts and washers absorb vibrations and impacts by elastic deformation with their unique shapes (skirt-shaped extended formation of internal space). The superior performance in reliability, workability, weather resistance, attachability and economic efficiency that has passed vibration tests is superior to conventional anti-loosening bolts/nuts. They are applicable to a wide variety of uses in railroads, bridges, buildings, civil engineering, vehicles, airplanes, construction machines and other vibratory products. [Representative's message] The fatal accident 10 years ago caused by a detached truck tire triggered our research on vibration absorption. A suction cup in a bathroom gave us a hint of shaping like a skirt. Our research for many years resulted in the development of catenary type fastening member that produces a high anti-loosening effect. We are determined to make efforts to enter into and contribute to the screw industry where safety, security and high quality are always demanded while, improving our technical capabilities. We will also advance into overseas markets. [Company structure for market development/overseas expansion] We have positioned new staffs to cater to our potential new customers. In Sunco Industries Co., Ltd., a study session for all salespersons is held to teach them know-how so they become the contact point for major companies and overseas companies. Our Engineering/Manufacturing Division staff will visit your workplace as required to solve any of your technical problems. Our president will provide sincere support for developing new customers and overseas companies as well as for gathering and managing necessary information.
