Bolts and nuts that can accommodate a variety of applications! Packed with helpful information for selection!

The "Bolt and Nut Handbook" is a catalog from Sanwa Iron Works Co., Ltd., which manufactures and sells bolts and nuts for piping and pressure vessels. It includes useful information for selecting bolts and nuts, such as types of bolts, shapes of nuts, and a list of standards. In situations like these... I want to know the standards of the screws currently in use! I want to find an equivalent product since I can't obtain the same one I'm currently using! I want to know about high-strength screws and nuts! You can find solutions in the "Handbook"! ★ We also offer a convenient business card-sized "Screw Handy Guide" as a gift. If you would like one, please contact us. (The content is almost the same as the handbook.) 【Contents (partial)】 ■ Types of bolts ■ Shapes of nuts ■ Stud bolt and nut weight calculation table ■ Bolt and nut hardness conversion table ■ Chemical composition standards list *For more details, please refer to the catalog or feel free to contact us.

A pipe thread with strong joint strength! Achieves excellent earthquake resistance, pressure resistance, and durability!

The "Rolling Nipple" is a pipe thread that has a strong connection strength with fittings and excels in earthquake resistance, pressure resistance, and durability. Traditionally, pipe threads used in piping fittings were mainly produced through cutting processes, but there were various performance issues due to the reduction of effective pipe thickness from cutting, as well as inconsistencies in thread precision and surface smoothness. Our product achieves a high-precision and smooth thread surface through rolling threads, improving the adhesion between male and female threads. It resolves the issues associated with cutting threads. 【Features】 ■ Earthquake resistance ■ Pressure resistance ■ Durability ■ Sealing performance *For more details, please refer to the catalog or feel free to contact us.
