The basics of materials for screws, steel materials. I will teach you tips for selecting materials according to processing methods and applications. Includes a material table by strength classification.

Steel is widely used as a material for screws because it is inexpensive, readily available, and strong. The main types of steel used for screws include carbon steel, which is primarily composed of iron and carbon, and alloy steel, which has elements such as chromium and molybdenum added. When strength and corrosion resistance are required for screws, the chemical composition of the steel can be altered, processing methods can be changed, or heat treatment can be applied to modify the material's mechanical properties. By utilizing the characteristics of the materials, various steel screws are produced to suit different applications and purposes. This document provides a clear explanation of the types and characteristics of steel materials suitable for screw processing methods and applications, as well as the strength classifications of steel screws, offering fundamental knowledge about steel materials for screws. *If you would like to learn more about steel materials for screws, please feel free to check the PDF document. Do not hesitate to contact us with any inquiries.*

This document explains why stainless steel does not rust and why it can rust. It is a technical document that outlines the types and characteristics of stainless steel.

Stainless steel is a highly corrosion-resistant alloy made by adding elements such as chromium and nickel to a base of iron to enhance its corrosion resistance. Due to its properties such as corrosion resistance, heat resistance, workability, and ease of maintenance, it is widely used in everyday items as well as large structures, with various applications ranging from household goods and transportation equipment to nuclear power and space development. Different types of stainless steel have been developed and manufactured to suit these applications. This document provides a clear explanation of the types and characteristics of stainless steel, the reasons for its rust resistance, and the conditions under which it rusts, offering fundamental knowledge about stainless steel. *For more details, please download the document or contact us directly.*

We are evaluating the performance of screws and fasteners. We will introduce the testing equipment and test examples to ensure the performance of the "screw"!

Screws are the fundamental mechanical elements that "connect things." Despite being small parts, the role of screws in "fastening" is significant. To fulfill this important role, various functions and performances are required of screws. Evaluations are diverse to confirm whether the "required performance is met." At Daiichi Industry, we assess the performance of screws and fastening bodies using various testing equipment. Due to the wide range of required functions and performances, many testing facilities are necessary, including those uniquely developed in collaboration with academia. What kind of equipment is used, and what items are evaluated? What evaluation results can be obtained from actual test examples? We introduce the test contents and inspection items with accompanying photos. Please check it out through the PDF download. Feel free to contact us as well.

A high-torque compatible embedded bolt for resin that is strong against rotation and withdrawal, and does not damage the resin. It allows for nut tightening when embedded in resin parts.

The "SSOO Bolt" is a resin embedded bolt (insert bolt) with a special octagonal head shape, offering excellent torque resistance and pull-out strength. An insert bolt is a bolt that is embedded in resin and fastened with a nut. By tightening with a nut, it allows for the fastening of resin parts to each other or resin parts to metal. It minimizes deformation and cam-out of the resin when fastened with high torque, enabling nut tightening at high torque levels. It can also be used for back embedding (thermal press fitting), making it suitable for shapes that cannot be integrally molded. Since the bolt can be used in an upright position within the resin, it improves the assembly of parts. The product design has been completely revamped, and sizes from M4 to M8 are now available. 【Features】 ● Special shape that minimizes cam-out and slip even when tightened with high torque ● Strong against pull-out, preventing deformation of resin parts ● Usable for both insert (simultaneous molding) and outsert (thermal press fitting) ● Mass production possible due to unique manufacturing methods ● Trusted Octa Lobular series *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Swallow Incubate Co., Ltd. has launched the Swallow Incubate Tech Blog, a technical site covering the implementation of liveness detection, face recognition and image processing. Developers who design and build face recognition systems have told us they lack the information needed to judge which technology to choose and what it can and cannot do. In particular, face recognition and liveness detection (protection against presentation attacks) are separate technologies - a point that is often recognised only at the implementation stage. The blog publishes that material. Our editorial rule is that every article carries implementation code and measured results. It is organised into three categories: Liveness Detection, OpenCV for C++, and OpenCV for C#.
