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.

Outstanding workability at a low cost! Introducing screws that are resistant to breakage and loosening.
The "Motion Tight N Type" has a structure that averages the load on the screw threads, which disperses the stress on the screw valleys, making it less likely to break. It reduces the variation in axial force to about half, providing a more stable axial force than standard screws. By simply tightening, it can effectively prevent loosening, allowing for proper torque management. It achieves low production costs through rolling processing, and it can be replaced with existing screws while maintaining high quality. 【Features】 ■ Fatigue strength 1.2 times higher, excellent workability ■ Stable axial force even without lubrication ■ High loosening prevention capability with the bolt alone ■ Low cost, high quality, reusable *For more details, please refer to the PDF document or feel free to contact us.
![[NS Low Head Introduction Case Study] Nursing Care Industry](https://image.www.ipros.com/public/product/image/2e5/2000483005/IPROS95475664950952647046.jpeg?w=280&h=280)
Introduction of examples in the nursing care industry that have led to injury prevention and weight reduction of parts!
Here is an example of the introduction of the "NS Low Head" in the nursing care industry. The "NS Low Head" has a low head height, making it suitable for use in narrow spaces. In the nursing care industry, there has been a demand to eliminate protrusions such as screws on products like beds and stretchers. This product features a low head shape that does not compromise the design of the product. By having a low head, it eliminates protrusions and allows the fastening area to be flat, which contributes to injury prevention and the reduction of component weight. [Example] ■ Implementation location: Nursing care industry ■ Implemented product: Ultra-thin head shape bolt "NS Low Head" *For more details, please refer to the PDF document or feel free to contact us.
