Daiichi Kogyo Co., Ltd. has been selected as a "Regional Future Leading Company"!

This is a strong insert nut that prevents slippage (co-rotation and idling) caused by bolt tightening and protects resin products from damage.

Insert nuts for resin (plastic) have traditionally utilized knurled, square, and hexagonal shapes, which have raised concerns about the nuts deforming the resin and spinning freely (slipping or idling) when bolts are tightened with high torque. As a result, we received strong requests from customers to develop insert nuts with shapes that can withstand high torque (high torque strength). We conducted research, development, and prototyping in-house and devised an original shape of insert nut that can handle high torque. It is designed for use during resin molding and also boasts excellent tensile strength (pull-out strength). 【Features】 - Strong nuts that prevent spinning (slipping or idling) and protect resin products from damage. - A unique octagonal shape that enables "high torque tightening," which has not been available before. - We have realized a shape that is difficult to spin, as requested by many customers. For more details, please contact us or download the catalog.

The three-blade design provides stable anti-loosening effects! Thanks to the high-strength friction ring, it can be reused multiple times! [Manufactured by Osaka Forming Co., Ltd.]

The "E-LOCK Nut" handled by Daiichi Industry features a three-blade design that enhances its anti-loosening function and possesses the strength to withstand repeated use. In the case of conventional two-blade products, one blade gets lodged in the thread valley, effectively resulting in a state of anti-loosening with only "one blade," leading to concerns about stability. However, this product's three-blade design effectively increases thread stability with "two blades." Additionally, durability tests under vibration showed no deformation in the three friction rings of this product, proving its ability to withstand repeated use due to the sustained effect of the springs. (Other manufacturers' nuts with high anti-loosening functions may experience deformation.) **Features** 1) The three-blade design provides a more stable anti-loosening effect compared to conventional products. 2) Prevents early detachment even if the tightening axial force decreases. 3) Strong and capable of withstanding repeated use. ★ This product is from Osaka Forming Co., Ltd.

Through research and development, we are striving to improve the safety, performance, and quality of our screw products!

Mechanical structures such as automobiles, home appliances, and buildings are assembled by joining multiple parts together. Therefore, joining is common across all industries and is the most fundamental technology for maintaining performance and quality. Joining can be broadly classified into welding through the melting and solidification of metals, chemical adhesion, and mechanical fastening through screws. Each of these methods has many advantages and is an important joining technique, but the only method that allows for high strength and the possibility of disassembly and reuse is mechanical fastening with screws, which is also considered to play an important role in today's environmental issues. Screws are a representative mechanical component that was standardized by ISO early on as a key element of globalization and are widely distributed in the market; however, there are significant differences in safety, performance, and quality among manufacturers. Through diligent research activities to meet users' needs for screw fastening, we are committed to improving the safety, performance, and quality of screw products.

The recognition that "the PDF invoice received from the other party must be stored as electronic data" is widely accepted. However, is that response truly sufficient for perfection? ◆ The "receipt" of electronic transactions includes issuance and delivery The Electronic Bookkeeping Act defines "electronic transactions" as the receipt of electromagnetic records related to transaction information. Breaking down the term "receipt" is key to understanding. - "Receipt": Receiving electronic data such as invoices and receipts from business partners - "Issuance": Issuing and delivering electronic data such as invoices and estimates to business partners When downloading a PDF from your company's accounting system and attaching it to an email, or concluding electronic contracts through a cloud-based invoicing service, both the receiving party and the issuing party (your company) are obligated to store the data. 【Utilizing paperlogic DESKTOP for document management】 - Elimination of manual input - Assurance of reliable searchability - Centralized management of receipt and issuance → paperlogic DESKTOP addresses the challenges of complex metadata management in the storage of these issued documents.
