Attention those struggling with spinning or pulling out nuts embedded in resin! Introducing outsert nuts that protect resin components and allow for high torque tightening.

"Do you have any of these concerns?" - When tightening conventional insert nuts, they can spin or come loose... - I am looking for an insert nut that can be embedded after resin molding... - I want to reduce the number of screw parts for weight reduction... - Brass insert nuts are expensive due to material and processing costs... With the 'SSOO Nut', these concerns can be resolved. 【5 Features】 ● A shape that is resistant to spinning, preventing damage to resin products ● Can be heated instantly by high-frequency vibrations, allowing for post-embedding ● Excellent pull-out strength enables reduction in the number of screw parts and weight reduction ● Uses a widely distributed material (SWCH10R), eliminating worries about material cost fluctuations ● High-speed production through forging and rolling. Allows for cost-effective mass production compared to machining *For detailed information about the SSOO Nut that can solve your concerns, please view the catalog available for download or feel free to contact us.

Non-magnetic, high-strength, and highly corrosion-resistant austenitic stainless steel bolts. They are environmentally friendly products that do not require heat treatment.

The "high-strength, high-corrosion-resistant stainless steel bolt" is made from austenitic stainless steel based on SUS304 and exceeds the strength classification A2 standard values of JIS B 1054. Through a proprietary molding process (patent obtained), it has achieved strength without the need for heat treatment. 【Features】 - Uses high-corrosion-resistant austenitic stainless steels SUS304 and SUS316 - Achieves high strength by utilizing material strength and work hardening through forging - The proprietary Bausinger effect suppression processing method eliminates the need for strengthening heat treatment, reducing environmental impact - Maintains high corrosion resistance and shortens lead time due to the absence of heat treatment processes - The screw head shape adopts a hexalobular design that offers high torque transmission - Balances corrosion resistance and strength, with a proven track record for use in automotive components (Note) The Bausinger effect refers to the phenomenon where, after applying plastic deformation in one direction, applying a load in the opposite direction results in plastic deformation occurring at a lower stress than when a load is applied again in the same direction. If you are interested in fastening with stainless steel components, please feel free to contact us.

The weight is about two-thirds that of iron! Titanium bag nuts (cap nuts) that are resistant to salt damage, rust, chemicals, and heat.

The founder of Daiichi Kogyo Co., Ltd., Akira Suzuki, was the first in Japan to manufacture and sell a bag nut (JIS Type 3 cap nut) with a cap pressed onto a nut. Since its release, it has received positive feedback for being lighter and more affordable compared to traditional cutting types, and it has evolved into a wide variety of forms to suit various applications. From this bag nut series, we offer lightweight and highly corrosion-resistant titanium cap nuts. 【Features】 ○ Lightweight (titanium is about two-thirds the weight of iron and half the weight of copper) ○ Excellent corrosion resistance, chemical resistance, and heat resistance ○ Smart design with excellent decorative qualities ○ Standardized and suitable for mass production 【Standard Sizes】Hexagonal type: Compatible with sizes M6 to M12. *Some are made to order. For more details, please contact us or download the catalog.

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.
