RENY Series ｜ High-Strength Plastic Screws for Structural Applications
🌟 Key Takeaways
- The RENY Series is a plastic screw series made from RENY (glass fiber–reinforced polyamide MXD6)
- Provides metal-like mechanical strength and fastening performance, suitable for structural applications
- Offers electrical insulation, lightweight design, and corrosion resistance
- Widely adopted in automotive, industrial machinery, structural components, and various industrial fields
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
In fastening design using non-metal fasteners, material selection has a critical impact on fastening strength, safety, and long-term reliability.
The RENY Series was developed specifically for applications where general-purpose materials such as PC or PPS do not provide sufficient fastening strength,
with high mechanical strength as its primary design objective.
🔷 What Is the RENY Series
Within the non-metal fastener lineup of Nippon Chemical Screw Co., Ltd., the RENY Series is positioned as a high-strength grade.
RENY is a glass fiber–reinforced polyamide (MXD6–based) material with exceptionally high mechanical strength.
As a result, RENY screws are used in certain applications as alternatives to metal screws.
At the same time, they retain the inherent advantages of plastics, including
lightweight construction, non-magnetic properties, and corrosion resistance.
🔷 When Fastening Strength Is a Key Design Requirement
In mechanical and structural fields, fastening points are often exposed to:
- High tensile and tightening loads
- Repeated loading and vibration
- Long-term, maintenance-free operation
The RENY Series is selected when designers need to achieve sufficient fastening strength with non-metal fasteners under these demanding conditions.
🔷 Key Features of the RENY Series
Based on product specifications and field applications:
- Very high mechanical strength : Suitable for high-load and vibration-prone fastening points
- Lighter than metal : Contributes to overall structural weight reduction
- Electrical insulation & non-magnetic : Ideal for electrical and electronic safety requirements
- Corrosion and environmental resistance : Stable performance in environments where rust or degradation is a concern
- Designed for structural-grade applications
🔹 The RENY Series enables high-strength fastening using non-metal materials.
🔷 Application Areas
🚗 Automotive & Energy-Related Fields
Used in automotive components, electrical modules, and battery-related parts,
from prototyping through mass production.
The balance of fastening strength and weight reduction is highly valued.
🏭 Industrial Machinery, Manufacturing Equipment & Infrastructure
Applied in industrial machines, jigs, fixtures, robots, production equipment,
as well as railways, ships, and factory facilities requiring structural reliability.
🔌 Electronics & Semiconductor Equipment
Used in locations requiring both high fastening strength and electrical insulation,
reducing electrical risks associated with metal fasteners.
🏥 Specialized Applications
Including medical devices, food processing machinery, and professional equipment,
where safety, durability, and strength are simultaneously required.
🔷 Suitable Usage Conditions for the RENY Series
- Fastening applications requiring high load capacity and strength
- Operating conditions where PC or PPS materials are insufficient
- Designs aiming to replace metal fasteners for weight reduction or corrosion resistance
- Non-metal fasteners used in near-structural applications
🔷 Next Material Selection Step
When applications require both higher strength and resistance to high-temperature environments,
the PEEK Series becomes the next recommended material option.
📘 Summary
The RENY Series is a high-strength plastic screw series that delivers metal-like fastening performance.
It supports designs seeking non-metal solutions, weight reduction, corrosion resistance, and high reliability,
particularly in structural, industrial machinery, and automotive applications.
