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.

"What is an insert nut?" "What is the difference between an insert nut and an outsert nut?" For those who have these questions, please check out our company's website on the "Basic Knowledge of Screws" page. Daiichi Kogyo, a total fastener manufacturer, explains the "basics of screws" that you may be hesitant to ask about. - A fastening technology specialist provides useful information about screws! Basic Knowledge of Screws <https://screw.daiichikogyo.co.jp/blog> We will clearly explain the characteristics and types of screws, fastening principles, as well as technical content such as materials, manufacturing methods, and surface treatments, along with images of our original products like insert bolts. Please take a look at the "Basic Knowledge of Screws" presented by our fastening technology specialists.

We have published a handbook summarizing the "materials" related to the strength and mechanical properties of screws. If you want to learn about screw materials, please take a look. A screw is a mechanical element used to fasten and secure parts together by tightening. There are many types of screws, and in recent years, due to increasing customer demands for corrosion resistance, resistance to loosening, lightweight design, and miniaturization, the selection of materials other than steel has also increased. The properties and strength of screw materials change depending on their composition and manufacturing methods. If inappropriate materials are used, the necessary force for fastening may not be achieved, increasing the risk of serious accidents due to loosening or breaking of the screw. The "Materials Edition" of the Screw Peripheral Technology Handbook introduces the mechanical properties of conventional steel materials, stainless steel, aluminum, titanium, and plastics. We hope it will be useful for your material selection. As a precision screw manufacturer, we handle a wide variety of bolt and nut products. Please feel free to consult us regarding product inquiries or any other concerns. [Contents included *For details, please refer to the catalog]

We have published a handbook summarizing the "processing methods" related to screw manufacturing, including molding processes, heat treatment, and surface treatment. The general process for manufacturing screws is carried out in the following steps: (1) material preparation → (2) molding process → (3) heat treatment → (4) surface treatment → (5) inspection → (6) shipping. To improve the strength and mechanical properties of screws, it is necessary to perform strong processing through screw molding, heat treatment, and surface treatment. The "Processing Methods" section of the Screw Peripheral Technology Handbook introduces general screw manufacturing methods (cutting and plastic processing) and methods for strengthening metals (heat treatment and surface treatment). If you want to learn about screw processing methods, please take a look. As a precision screw manufacturer, we handle a wide variety of bolt and nut products.
