Stainless steel, known for its properties such as corrosion resistance, heat resistance, and workability, as well as its ease of maintenance, is widely used in everything from everyday household items to large structures. Stainless steel is also commonly used as a material for screws. We are currently offering a technical document titled "Why Doesn't It Rust?! Basic Knowledge of Stainless Steel: Understanding Types and Characteristics," which clearly explains the types and characteristics of stainless steel, the reasons it is resistant to rust, and the conditions under which it can rust, complete with illustrations. If you want to learn the basics of stainless steel, please take a look.

Do you know about the performance evaluation of screws? Screws are often perceived as standard products, but many of the precision screws we handle are developed through various performance evaluations based on customer requirements. Screws are fastening components that significantly impact the strength of mechanical structures. Loosening or breaking of screws can lead to major accidents. The performance evaluation of screws includes many items, such as the unique "axial force," "loosening," and "tensile strength," as well as the screw's own "durability," "mechanical strength," and "fatigue strength." Our company is equipped with testing facilities to conduct evaluations for each of these performance aspects. We have summarized the types of equipment we use for performance evaluation. Each test is explained with photos, detailing the overview of the testing machines, as well as the purpose and content of the tests. Some of the testing machines have been developed in collaboration with academic institutions. *Specific examples of tightening tests and delayed fracture tests have been added. Please take a look at the performance evaluations accumulated by Daiichi Kogyo Co., Ltd. as a total fastener manufacturer. Feel free to contact us with any inquiries.

We would like to introduce a document summarizing case studies of SSOO nuts. SSOO nuts are 'heat-pressed insert nuts (outsert nuts)' that achieve high "torque resistance" and "pull-out strength." They prevent nut rotation (slipping) and pull-out that can occur during high-torque tightening, ensuring safe fastening of plastic products. The features of SSOO nuts have solved various problems for our customers. [Case Study 1] - High tightening torque is required, but the insert nut rotates. → Meets tightening requirements with high torque resistance. Fastens plastic components without rotation. [Case Study 2] - Want to reduce the number of screws used for weight reduction. → Achieves a reduction in the number of screws while ensuring fastening strength with high pull-out strength. Additionally, we have realized many benefits, including reducing environmental impact and responding to strong vibrations. For more details, please download the document or feel free to contact us.

Why was the SSOO nut adopted? We will explain it clearly through case studies. We are currently offering free materials that explain the benefits of adopting the SSOO nut. *This material was published in December 2023. The SSOO nut is a press-in insert nut that is gentle on resin parts and contributes to weight reduction. Even when tightened with high torque, the nut does not spin (co-rotate), preventing damage to the resin parts. Additionally, its high pull-out strength allows for a reduction in the number of nuts used compared to conventional methods. We introduce case studies and performance test results of the SSOO nut, along with the benefits of its adoption, accompanied by photos. We also include examples of reduced environmental impact by switching to iron SSOO nuts.
