Bolts. They are mainly used in transportation equipment parts and are also engaged in research and development.
Bolts are one of the essential mechanical components for fastening products and are used in various machine structures. Our company, as a total fastener manufacturer supporting Japanese industry, produces and sells a wide variety of bolt products, including high-strength bolts, flange bolts, washer-integrated bolts, welded bolts, riveted bolts, and serration bolts. We also have manufacturing and sales bases overseas, including in China and India, to meet our customers' needs. So far, we have developed and mass-produced stainless bolts made from stainless steel SUS304, achieving high strength and corrosion resistance without heat treatment, as well as aluminum bolts based on aluminum alloy A7050, which achieve high strength through a special strengthening process. If you are interested, please feel free to contact us.
A manufacturing method that ensures strength without heat treatment through an independent forming process, taking environmental impact into consideration.
Plastic deformation is applied to metals, and as the degree of deformation increases, work hardening is achieved, resulting in a higher yield point than the original metal. The metal exhibits strong resistance to loads in the direction of the work hardening, but the yield point against loads in the opposite direction decreases, making it easier to undergo plastic deformation at lower stress levels. This phenomenon is called the Bauschinger effect. Our company has developed and launched a molding process technology that suppresses the Bauschinger effect. This special molding process enables the production of bolts with mechanical properties without the need for heat treatment. Non-quenched, medium-strength bolts are products that secure a strength classification equivalent to 8.8 without heat treatment. The absence of heat treatment reduces environmental impact and shortens manufacturing lead times. From development to evaluation, our team of experts is here to assist with the optimal design of screws. Please feel free to reach out to us.
We provide various technical information, including test results and material properties, about "high-strength, high-corrosion-resistant stainless steel bolts" that excel in strength and corrosion resistance.
The "high-strength, high-corrosion-resistant stainless steel bolt" is made from austenitic stainless steel materials SUS304 and SUS316, which excel in corrosion resistance. By utilizing forging processes to enhance material strength and work hardening, it surpasses the JISB1054 A2 standard values. 【Verification Experiment】 Stainless Steel Bolt Tensile Test (Size: M8 P1.25) ○ Tensile Strength: 1018.3 MPa ○ 0.2% Yield Strength: 854.6 MPa By introducing our self-developed Bauschinger effect suppression processing method into the manufacturing process, we have made it possible to secure strength without heat treatment. ○ It allows for strong processing without enhanced heat treatment, reducing environmental impact. ○ By eliminating the heat treatment process, lead time can be shortened. (※) The Bauschinger 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. This stainless steel bolt achieves both corrosion resistance and strength while also contributing to cost reduction. Detailed technical information is available in the technical report.

![[Technical Data] High Torque Compatible Resin Embedded Bolt "SSOO Bolt"](https://image.www.ipros.com/public/product/image/657/2000640145/IPROS18041682138058844781.jpeg?w=280&h=280)
Free technical documentation for the resin embedding bolt "SSOO Bolt" is available. It includes results from verification tests such as torque strength tests and pull-out load tests, as well as specifications.
The high-torque compatible embedded bolt "SSOO Bolt" features a special octagonal head shape that prevents slipping, protecting the resin from damage and enabling tightening at high torque. This document is a technical report that includes experimental results such as torque strength tests and pull-out load tests for the SSOO Bolt, as well as specifications and other technical information. ● Usable for both insert during molding and outsert after molding The method of inserting the bolt can be adapted to suit the application. ● Since the bolt can be used in an upright position in the resin, the assembly of parts is also improved. For detailed technical information, please refer to the download.
From the development stage, the bolt shape has been redesigned for weight reduction!
The "SSOO Bolt" is a high-torque embedded bolt (insert bolt) designed for resin that minimizes deformation and rotation of the resin when tightened with high torque, and is also resistant to pull-out. This bolt is embedded in the resin component with its head, and is secured with a nut. Since the male thread of the bolt stands above the resin, it improves the assembly characteristics of the components. It has been successfully used in the junction boxes and busbars of the traction motor system "e-Axle." Please feel free to contact us if you would like a sample. 【Features】 ■ Minimizes deformation and rotation of the resin when tightened with high torque, and is resistant to pull-out ■ Improved assembly characteristics due to the standing threads of the bolt ■ The special octagonal shape of the head and the serrated grooves on the outer circumference allow the resin to easily engage when embedded ■ Can be embedded either through simultaneous molding or post-insertion via thermal press fitting ■ The shape of the bolt head has been modified for weight reduction *For more details, please refer to the PDF document or feel free to contact us. *Thread sizes range from M4 to M8.

A reduction of approximately 79% in process time is possible compared to conventional construction methods! [Technical materials including construction achievements are currently being distributed.]
In recent years, the installation of anti-fall devices and similar measures in seismic reinforcement work for existing bridges has been increasing. For the bracket fixing method on RC structures, adhesive post-installed anchor bolts are used, with epoxy resin-based adhesives being commonly employed. However, challenges include long curing times, failure to cure at low temperatures below 5°C, and poor adhesion on wet surfaces. To address these issues, we have developed an adhesive post-installed anchor using "acrylic resin," called "NR Anchor" and "R Anchor." (The "R Anchor" is a removable anchor bolt.) By using acrylic resin, it is possible to achieve approximately a 79% reduction in process time compared to conventional methods. ■□ We are providing technical materials that include construction achievements! □■ 【Contents (excerpt)】 - About acrylic resin - Performance verification tests - Construction achievements ■□ For more details, we will contact you from the manufacturing company of the R Anchor, "Sanpo Co., Ltd." □■ *For more details, please inquire or refer to the catalog.
