basic information
**Features** ■ Torsion Shape High Strength Bolt (S10T) Developed to simplify construction management and improve construction accuracy, this is a high-strength bolt set that complies with the standards of the Japan Steel Structure Association and the Japan Road Association. It is manufactured through a consistent process from steelmaking and rolling to product shipment, boasting high quality and certified by the Minister of Land, Infrastructure, Transport and Tourism. ■ High Strength Hex Bolt (F10T) Similar to the torsion shape, this product is manufactured under strict quality control through a consistent process from steelmaking and rolling to bolt set shipment, and it is a high-quality product certified with JIS marking. The material is made from dedicated high-quality steel, particularly excelling in resistance to delayed fracture characteristics. ■ Hot-Dip Galvanized High Strength Bolt (F8T) When using hot-dip galvanized high strength bolts in construction structures, it typically requires certification from the Minister of Land, Infrastructure, Transport and Tourism for each construction structure. However, the bolts we provide have obtained certification for "Hot-Dip Galvanized High Strength Bolt Joints" from the Minister. Therefore, when using our hot-dip galvanized high strength bolts and conducting design and construction in accordance with the "Design and Construction Guidelines" and "Construction Management Guidelines," you can use them freely without needing individual certification for each project.
