Construction-related products: hot-dip galvanized high-strength hex bolts

Construction-related products: hot-dip galvanized high-strength hex bolts

We have undergone examination based on the Building Standards Act and obtained general certification from the Minister of Land, Infrastructure, Transport and Tourism.

The high-strength hex bolts with hot-dip galvanized coating from Teikoku Seibou Co., Ltd. have undergone examination based on the Building Standards Act regarding corrosion resistance, mechanical properties, tightening functionality, delayed fracture characteristics, and construction performance, and have obtained general certification from the Minister of Land, Infrastructure, Transport and Tourism. The coating weight of the bolts, nuts, and washers is 550g/m² or more. Furthermore, the coating weight of the components is managed under the same standards, ensuring maintenance-free corrosion resistance over the long term. In the zinc plating process, acid washing is avoided as much as possible to prevent hydrogen intrusion, eliminating concerns about delayed fracture. The nuts are treated with a special lubrication process, guaranteeing stable axial force during tightening construction using the nut rotation angle method. *For urgent or emergency cases, or for technical inquiries, please contact us directly through our website.*

Magnet (Neodymium cap magnet) round hex bolt with anti-slip rubber.

Magnet (Neodymium cap magnet) round hex bolt with anti-slip rubber.

To enhance the adhesive force, the neodymium magnet is covered with an iron cap. The magnet is secured with a hex bolt, and the length can be adjusted and tightened with a hex nut and a wrench.

There is a slight gap between the magnet and the hex bolt, allowing the magnet (φD) part to rotate freely. By using the separately sold [bracket for horizontal and vertical types with hex nut], it can be installed in various orientations. By attaching the included anti-slip rubber to the adhesion surface, it provides scratch prevention and slip resistance.
