KYOUJIN Series ｜ Ultra-High Strength Plastic Fasteners Designed to Replace Metal Screws
🌟 Key Takeaways
- KYOUJIN Series is a plastic fastener developed entirely from scratch with a new design concept
- The highest mechanical strength among all plastic fasteners in our product lineup
- Made from fiber-reinforced thermoplastic resin
- Specifically engineered as a metal screw replacement
- Combines high tensile strength, electrical insulation, non-magnetic, and corrosion resistance
- Intended for infrastructure, construction, industrial machinery, and heavy electrical equipment
ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー
🔷 The Role of Fasteners in Advanced Engineering
In high-level engineering applications, fasteners are not merely joining parts.
They are functional components that directly affect:
- Structural strength
- System safety
- Long-term reliability
Conventional plastic fasteners often lack sufficient strength, while metal fasteners introduce issues such as:
- Increased weight
- Corrosion
- Electrical interference
- Magnetic effects
The KYOUJIN Series was developed to solve these challenges with a clear goal:
👉 true replacement of metal screws using non-metal fasteners.
🔷 What Is the KYOUJIN Series?
The KYOUJIN Series is an ultra-high strength plastic fastener line under the CHEMIS X brand, developed by Nippon Chemical Screw Co., Ltd.
Unlike conventional products, KYOUJIN is not an extension of existing materials.
It was engineered from the ground up by fully optimizing:
- Material selection
- Fiber content and orientation
- Thread geometry and dimensional design
This integrated approach achieves the highest mechanical performance among the company’s plastic fasteners.
🔷 Design Philosophy: Metal Screw Replacement
The KYOUJIN Series was designed for fastening points that traditionally required metal bolts, delivering:
- High clamping and tensile strength
- Long-term structural reliability
- Unique advantages of non-metal materials
As a result, KYOUJIN is positioned as a non-metal fastener suitable for structural and high-load applications.
🔷 Key Engineering Characteristics
- Ultra-high tensile strength: Highest level among in-house plastic fasteners
- Lightweight: Significant weight reduction compared to metal fasteners
- Electrical insulation & non-magnetic: Ideal for electrical and control systems
- Corrosion resistance: Suitable for outdoor and corrosive environments
- Reduced thermal and electrical conductivity: Improves system safety
🔹KYOUJIN Series achieves the highest balance of strength, lightweight design, and non-metal functionality.
🔷 Typical Applications
🏗️ Infrastructure & Construction
Structural fastening points requiring high reliability and durability.
🏭 Industrial Machinery
Manufacturing equipment, robots, and machine structures under continuous high loads.
⚡ Heavy Electrical Equipment
Applications requiring high strength together with insulation and non-magnetic properties.
🚗 Automotive & Energy (Applied Fields)
Structural components demanding both strength and weight reduction.
🔷 Suitable Usage Conditions
- When replacing metal screws
- Applications requiring extremely high fastening strength
- Cases where standard engineering plastics are insufficient
- Designs demanding lightweight, insulation, and corrosion resistance
- Structural applications prioritizing long-term reliability
🔒 Trust
Performance data and product classification of the KYOUJIN Series are based on official technical documentation and CHEMIS X brand materials from Nippon Chemical Screw Co., Ltd.
An integrated in-house system covering design, tooling, and molding ensures stable quality for demanding industrial applications.
🔎 Next Step in Material Selection
For designs requiring maximum strength, lightweight performance, and non-metal characteristics, the KYOUJIN Series represents the ultimate solution in plastic fasteners.
📘 Summary
The KYOUJIN Series is an ultra-high strength plastic fastener developed from scratch with the explicit goal of replacing metal screws.
It provides a realistic and reliable alternative for infrastructure, construction, industrial machinery, and heavy electrical equipment where strength, safety, and durability cannot be compromised.
