The "Kobe Steel High Tension Bolt" allows for stable tightening axial force and flawless construction. Since it is manufactured under a consistent quality control system, the quality is uniform. This ensures that the torque coefficient value is stable, allowing for a consistent axial force. Please feel free to contact us if you have any requests. 【Features】 ■ Stable tightening axial force ■ Stability of torque coefficient value ■ Minimal rotation of bolts and washers together *For more details, please download the PDF or contact us.

The 'Shinko Hot-Dip Galvanized High-Strength Bolt' improves corrosion resistance through surface treatment with hot-dip galvanization. The coating weight is 550g/m2 or more, the same as the material. Compared to the coating weight of 350g/m2 for medium bolts, it is thicker, providing long-term corrosion protection. [Features] ■ Coating weight of hot-dip galvanization is 550g/m2 or more ■ The threaded parts of bolts and nuts are processed before coating ■ Stable strength ■ Stable workability ■ Suitable for construction and civil engineering *For more details, please download the PDF or contact us.

The "Shinko Hexagonal Torque Control Bolt" was developed to solve the problem of not being able to use torsional high-strength bolts in temporary construction. The tightening axial force is stable and construction is possible. Please feel free to contact us if you have any requests. 【Features】 ■ Torque coefficient is stable against temperature changes ■ No forgetting to tighten ■ Does not require skilled tightening ■ Easy to disassemble *For more details, please download the PDF or contact us.

The 'Weather-Resistant Shinko High-Strength Bolt' generates a dense amorphous layer continuously on the base metal, suppressing the permeation of water and oxygen, making it easier to form stable rust. It suppresses the formation of galvanic cells between nickel-based high-weather-resistance steel plates. It is adjusted to have a corrosion potential similar to that of the steel plate. [Features] ■ Suppresses the permeation of water and oxygen ■ Corrosion prevention effect ■ Corrosion potential similar to that of the steel plate ■ Can be used as a bolt specifically for Kobe Steel's long-life coating steel plate 'Eco View' ■ High-strength bolts with rust stabilization treatment are also manufactured *For more details, please download the PDF or contact us.

The "Anti-Corrosion Treatment Shinko High-Tension Bolt" has a surface treatment that excels in corrosion resistance and compatibility with topcoats. Corrosion resistance has been tested in two ways: a salt spray test for 100 hours and a weather resistance test for 1000 hours, with no abnormalities observed. 【Features】 ■ Excellent compatibility with topcoats and corrosion resistance ■ Joint characteristics (slip resistance, stress relaxation, loosening, etc.) are comparable to standard high-strength bolts ■ No contamination from anti-corrosion oil, and no adhesion of dust or debris ■ Bolt performance equivalent to standard high-strength bolts ■ The threads of the nuts are over-tapped before anti-corrosion treatment, but this does not affect strength *For more details, please download the PDF or contact us.

The "Rust-Resistant Treated Sectioned Double-Thread High-Strength Bolt" has been developed for use in panel joints of steel composite floor slabs and has been adopted in numerous construction projects. Since the composite floor slab can be fixed to the panel before being installed on the bridge girder, bolt tightening can be performed with only top-side work during construction. 【Overview】 ■ The shaft has a section (Φ25.5mm) and is threaded at both ends. ■ Composed of one bolt, two nuts, and two washers. ■ There are two types of nuts: one for the bolt fixing side (white) and one for the connecting plate side (green). ■ The two washers are the same. ■ Surface treatment for rust prevention is applied to the bolt, nuts, and washers. *For more details, please download the PDF or contact us.
