[First Industrial Co., Ltd.] is currently publishing "Useful Information about Screws" on its website. A leading fastener manufacturer explains the basics of screws and more.

[Attention Engineers] The Basics of Screw Manufacturing Technology: "Forging Process." We are currently offering free technical materials on "Basic Knowledge of Forging Process," which explains the differences in the manufacturing of bolts and nuts.

Many "screw products" such as bolts and nuts are manufactured using "forging." "Forging" is a processing method that uses molds to shape metal materials by compressing them. It has many advantages, such as good yield, suitability for mass production, and increased strength due to work hardening. Although both are "screw products," bolts and nuts differ in materials, manufacturing processes, and manufacturing equipment. At Daiichi Kogyo, as a specialized group that manufactures both bolts and nuts, we have accumulated production and manufacturing technologies that correspond to each of these differences. We also utilize FEM analysis to conduct forging simulations, which are applied in process design and mold design. The reason we can manufacture both bolts and nuts can be found in the link below: "Production and Manufacturing Technology of the Specialized Group." A specialized group that manufactures both bolts and nuts has compiled "Basic Knowledge of Forging." We provide a clear explanation of the actual processing steps with accompanying photographs. Improvement examples utilizing FEM analysis are also included. Please download and take a look.

[Attention Engineers] Screw manufacturing is not just about forging. There is also cutting and welding. We offer a free [technical document] that provides fundamental knowledge of each technique!

Daiichi Kogyo is a specialized group that develops and manufactures fastening components, including bolts and nuts. 【What a specialized group can do】 While "forging" is the common method for screw manufacturing, "cutting" is also an important processing technique for screw production when complex shapes or additional processes like drilling are required. Daiichi Kogyo possesses the manufacturing know-how necessary for "forging," "cutting," and "welding" in screw production. We can perform "composite processing" that combines these techniques. Forging + Cutting + Welding ⇒ Composite products With the accumulation of each processing technique, we can set up processes that leverage the characteristics of each method. 【Manufacturing Example】Production of parts with strict precision requirements. ● When manufactured using only "forging," the load on the mold increases, raising concerns about mold lifespan and quality deterioration. ↓ ● By switching from "forging" to "cutting" for manufacturing, we can reduce the load on the mold and lower forging costs, achieving quality improvement as well. For more details, please visit the following 【Daiichi Kogyo Co., Ltd. Fastener Division Fastening Components Site】. We are currently offering free technical materials that provide basic knowledge of screw manufacturing techniques, including "cutting and welding." Please download and take a look.

What is delayed fracture? Why does hydrogen embrittlement occur? What are the prevention measures? I will explain the basics of delayed fracture and hydrogen embrittlement in an easy-to-understand manner.

Are you familiar with "delayed fracture of screws"? "Delayed fracture" refers to the phenomenon where a static stress (tensile or bending load) is applied at room temperature for a certain period of time, and then it suddenly fractures without any apparent plastic deformation. Despite the absence of large or repeated loads, the bolt suddenly fails... It might be due to delayed fracture. In fact, the mechanism behind "delayed fracture" has not been fully elucidated. The phenomenon of hydrogen embrittlement is considered to be an important factor. - What is delayed fracture? What are its testing methods? - What is hydrogen embrittlement? What are the countermeasures? This is a technical document that provides a basic understanding of these topics. Please refer to the PDF for more details. As a specialist in manufacturing both bolts and nuts, our company conducts performance testing and evaluation from the development stage at our R&D center to ensure that we meet our customers' performance requirements.

You will understand the basics of "surface treatment" that improves the corrosion resistance and appearance of screws. This will explain the characteristics of representative surface treatments.

Metal screws, such as those made of iron, will corrode and rust due to electrochemical reactions after being molded for a while. Corrosion and rust can lead to poor appearance and reduced strength of the screws. To prevent such issues, surface treatment is applied to improve the rust and corrosion resistance of the screws. There are many types of surface treatment methods, each differing in functions such as corrosion resistance and appearance (color). It is necessary to choose the optimal surface treatment according to the purpose and usage environment. This document clearly explains the characteristics of commonly used surface treatments for screws: "Electrogalvanizing," "High Nickel Type - Zinc-Nickel Alloy Plating," and "GeometⓇ Treatment." It is a compact version that can be easily viewed. [Contents] ● Main types and overviews of surface treatments ● Surface treatments commonly used for screws For those who want to know more about surface treatments for resin fastening components, you can view more details here.
