Bolts and nuts that can accommodate a variety of applications! Packed with useful 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 such cases... I want to know the standards of the screws currently in use! I want to find an equivalent product when the same one I am using is unavailable! I want to know about high-strength screws and nuts! These can be resolved with 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 strong bonding 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 this led to various issues in performance due to the reduction of effective pipe thickness and inconsistencies in thread precision and surface smoothness. Our product achieves a high-precision and smooth thread surface through rolling, 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.

This is a high-strength stainless steel bolt that achieves high strength, corrosion resistance, high-temperature resistance, and low-temperature impact resistance.

The High Strength 100 Series is a high-strength stainless steel bolt that takes advantage of the main components of stainless steel, such as Ni, Cr, and Mo, while enhancing the cold work rate in our own factory. It excels in high-temperature resistance, corrosion resistance, and low-temperature impact resistance. As fastening components for equipment used in ultra-low temperature high pressure and high temperature high pressure applications, stud bolts, embedded bolts, and chemical anchors are now available for use. 【Features】 - Custom-made products possible due to in-house manufacturing - High strength with a tensile strength of 1,000 N/mm² - High strength even at elevated temperatures - Absorbs low-temperature impact energy despite high strength - Longer lifespan compared to iron, reducing the hassle of replacements For more details, please contact us or download the catalog.

Custom-made insulating bolts and nuts.

The bolts and nuts are manufactured and sold not only based on the distinction between iron and stainless steel but also according to specifications regarding material, strength, and plating. Since they are made to order, there is flexibility in the shape of the bolt body and insulating parts. The bolts and nuts can comply with not only JIS standards but also ASTM and ANSI/ASME, and various test certificates can be issued.

This is a notice for the rebroadcast of the co-hosted seminar with Live Consulting Co., Ltd. held on September 11 and 15, 2026. "The New AI Tools Are No Longer Needed" This seminar allows participants to experience Microsoft Copilot, which can be used directly within familiar Word, Excel, and Teams, through a demonstration of actual operating screens. The answers are already within your existing Microsoft 365. You can use AI directly in Word, Excel, and Teams without the need for additional tool selection, all within the security framework of M365. We will explain the basics to practical applications of Copilot in 90 minutes, aimed at executives and managers in the manufacturing industry. We sincerely look forward to your participation. 【Recommended for】 - Executives and managers in the manufacturing industry who have not yet mastered generative AI/Copilot - Those considering AI implementation but are stalled due to tool selection, security, or promotion systems - Those who prefer to see "actual screens" rather than just "reading" before making a decision - Those who are concerned about security and cannot use ChatGPT in their company

We will be exhibiting at "CEATEC 2026," which will be held at Makuhari Messe from October 13 to 16. We provide information technology and process informatics (PI) that optimize "how to create" using physical simulations, AI, and machine learning in process development. We look forward to your visit to our booth. 【Seminar Information】 "Process Informatics for Exploring Optimal Manufacturing Conditions" Date and Time: October 16, 2026 (Friday) 12:45 - 13:00 Venue: Makuhari Messe Exhibition Hall 4 P Stage Speaker: CEO Takaishi Please check the link below for details on our exhibition.

In recent years, weather risks that affect construction sites, such as localized heavy rain, strong winds, and extreme heat, have been increasing. In response to this situation, more companies are implementing weather information services at the company or branch level to manage weather risks across multiple sites collectively. On the other hand, is there a challenge where "the company checks weather information, but it is not used much on-site"? To implement weather measures across the entire company, it is important not only for managers to easily grasp multiple sites but also for the personnel working on-site to be able to easily check the information necessary for their specific site. We are releasing a new feature called "Field View." For more details, please visit our website.
