You will understand the basics of screws. You will also learn about performance evaluation and manufacturing methods. This is a new website dedicated to fastening components!

We are engaged in product development and performance evaluation to shape our customers' requests. We provide testing evaluation equipment and examples of evaluations. We will teach you the basics of performance evaluation.

Screws are small components, but they play a significant role as functional parts in "fastening." Performance evaluation is essential to shape our customers' requests. For example, we have a series of screws designed for special octagonal shapes in resin. The starting point was a customer's request for a nut that wouldn't rotate when embedded in resin. Using FEM analysis, we selected the optimal shape from 40 different designs. Collaborating with the production technology and manufacturing departments, we developed an insert nut that can withstand high torque fastening. To turn requests into reality, it is necessary to have evaluation capabilities to ensure proposed performance. During the development stage, we need to consider performance requirements and mass production feasibility, and after development, we must confirm the design performance and mass production quality, among various evaluations. Our company is equipped with various testing and evaluation facilities, including those developed in collaboration with academia. You can understand the basics of screw performance evaluation, including what kind of equipment is used and what evaluations are conducted. We also provide actual evaluation examples. Please take a look at our development and evaluation tests to shape our customers' requests. More details can be downloaded, and feel free to contact us with any inquiries.

This document clearly explains the forging process of bolts, nuts, and collars. It provides information on the basics of screw manufacturing technology, specifically "forging."

"Forging processing" refers to a type of plastic processing that shapes metal materials using molds. Unlike cutting processes, it minimizes material waste and is suitable for mass production. At Daiichi Industry, we manufacture both "bolts" and "nuts" through "cold forging processing." This document includes the advantages and disadvantages of forging processing, as well as examples of the forming processes for bolts and nuts/colors. It also illustrates the differences in manufacturing methods for bolts and nuts with accompanying photos. Additionally, we present examples of improvements in mold design using FEM analysis. <Note> We have added "Types of Cold Forging Processing" to the document. It explains how screws are formed using dies and punches, accompanied by illustrations. For more details, please refer to the download. Feel free to contact us with any inquiries.

We are offering the textbook "Learning the Basics of Screws" for free, which helps you understand the fundamentals of screws. It includes topics such as "How Tightening Works" and "Loosening and Countermeasures," and is available as part of a series.

Screws are the fundamental mechanical elements that "connect things." They are utilized in various fields, including automobiles, buildings, computers, robots, as well as in asteroid exploration and medical applications. It is said that screws are so common that they can be found "within a radius of 1 meter." Do you know what types of screws exist? You can easily find out by looking at Screw Textbook Vol. 1 [Basic Terms and Types]. Do you know why screws tighten? Screw Textbook Vol. 2 [The Mechanism of Screw Tightening] explains it clearly with illustrations. Do you know why screws loosen? Screw Textbook Vol. 3 [Loosening and Countermeasures] provides a detailed explanation of the mechanisms behind screw loosening and preventive measures. Are you familiar with screw fastening design? Screw Textbook Vol. 4 [Screw Design Part 1] offers an easy-to-understand explanation of the fundamental knowledge necessary for screw fastening design. If you want to learn about screws from the basics, please refer to the PDF materials. Feel free to contact us with any inquiries.

Cannot secure the resin. The resin cracks. "Screws for insert molding" support the fastening of the resin. Free distribution of "Basic Knowledge of Insert Nuts" is ongoing!

Are you having trouble with fastening resin products? You want to tighten them strongly, but the resin cracks. Conventional fastening designs can't be used. You can bond with resin clips or adhesives, but it's a problem if they can't be removed... We have a solution for such "troubles": "screws for insert molding." "What are screws for insert molding?" We offer a technical document that answers that question for free. An insert nut is one type of screw for insert molding. By embedding it in the resin and reinforcing the fastening part, it enables fastening of resin using "bolt + nut." We clearly explain why insert nuts are necessary, how to use them, and the types of resins used, covering the "basics of insert nuts." Our company manufactures the "Octa Lobular Series," screws specifically for fastening resin products. With a special octagonal head shape, it ensures 1.8 times the torque resistance and pull-out strength compared to knurled products, protecting the resin and achieving high-torque fastening. We solve the "troubles" of fastening resin. Please check the detailed documentation of the series available for download. We also have a wide variety of colors for resin. Feel free to contact us with any inquiries.

We have newly added the "RB Catcher," a log capture device installed on impermeable sediment control dams in flow sections, to our product lineup and have started sales. The RB Catcher is directly attached to the upstream part of the impermeable sediment control dam to enhance log capture functionality. Unlike the conventional straight arrangement, it features a structural layout that creates gaps between units, ensuring that water flow is maintained without causing blockages after capturing logs. This allows for the reliable capture of subsequent logs without overflow, preventing damage downstream. By adding this new log capture device to our lineup, we will flexibly respond to various needs in the field.

We have introduced Majesta Fragrance to a luxury lounge establishment located in the Kitashinchi area of Osaka. This time, we have adopted "Majesta Fragrance" as part of the in-store space branding. The moment you open the door, you are enveloped in a delicate and sophisticated scent, as if wrapped in high-quality silk. The elegant atmosphere reminiscent of a luxury hotel lounge invites customers into an extraordinary world. Majesta Fragrance has been implemented as an invisible scent branding in many establishments and companies. For scent production in the Kansai area, please leave it to Majesta Fragrance. If you are interested in scent production, please feel free to contact us.

This time, the ACS-5000 is available as a facial recognition terminal compatible with FaceMe Security's add-on feature "Face Terminal," enabling access control management that combines "advanced anti-spoofing features" with high-speed facial recognition powered by edge AI. ■ Main Features 1. Accelerated Authentication Processing FaceMe Security is optimized for the MediaTek Genio 700's NPU, achieving faster facial recognition processing and reduced CPU load compared to processing with only the CPU. It ensures stable authentication without delays even during peak times, such as clocking in and out, contributing to alleviating congestion. 2. Advanced "Anti-Spoofing" Optimized for the IR + RGB camera mounted on the ACS-5000. It can quickly detect fraudulent authentication using photos, videos, or 3D masks within 0.6 seconds, ensuring reliable identity verification. 3.
