It has excellent design, corrosion resistance, and durability, and is widely used in various fields.
Stainless steel is excellent in design, corrosion resistance, and durability, and has been widely used in various fields for a long time. High-strength hex bolts used for stainless steel structural materials are regulated by JIS B1186 "Set of High-Strength Hex Bolts, Hex Nuts, and Flat Washers for Friction Joints." However, since the chemical composition and manufacturing methods of the material are not specified here, high-strength hex bolts made of stainless steel are manufactured based on the standards of the Stainless Steel Structural Engineering Association, SSBS301 "Set of High-Strength Hex Bolts, Hex Nuts, and Flat Washers for Structural Stainless Steel" (10T-SUS, 10-SUS, 35-SUS). *For urgent or emergency cases, or for technical inquiries, please contact us directly through our website.
We can manufacture bolts of all sizes according to user needs.
There are two types of hexagon head bolts based on the size of the width across the flats: 1. Standard hexagon bolts (regular hexagon bolts), and 2. Small hexagon bolts (hexagon bolts with a head width across the flats smaller than that of standard ones). The applicable strength grades are 4.6, 8.8, and 10.9. Teikoku Seiko Co., Ltd. can manufacture bolts of all sizes according to user needs. Additionally, since October 1993, Teikoku Seiko Co., Ltd. has been producing high-strength hexagon bolts with a diameter of 10.9 (JIS standard) using advanced heat treatment technology that leverages hot forging technology (with a maximum shank length of 1,000 mm possible). *For urgent or emergency inquiries, or for technical questions, please contact us directly through our website.
