PA Series ｜ Plastic Components for Surface Protection and Electrical Insulation in Industrial Applications
🌟 Key Takeaways
- PA Series is a range of fasteners and plastic components made from PA (Polyamide / Nylon)
- Primarily used as washers and auxiliary parts in combination with metal screws
- Contributes to surface protection, damage reduction, and electrical insulation
- Suitable for automotive electrical systems, OA equipment, and home appliances
- Designed for protection and insulation, not for primary load-bearing purposes
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
🔷 Overview of the PA Series
The PA Series is a plastic component line developed by Nippon Chemical Screw Co., Ltd.
Rather than serving as primary fastening elements, these components are designed to enhance the safety and reliability of fastening points by providing surface protection and electrical insulation.
🔷 Core Concept of the PA Series
- Not intended to support primary structural loads
- Functions as a spacer or buffer between metal fasteners and mating materials
- Reduces problems caused by direct metal-to-metal contact
🔷 Material: PA (Polyamide / Nylon)
- Engineering-grade plastic material
- Good mechanical strength for auxiliary fastening use
- Lightweight and highly versatile
- Ideal for washers and protective support components
🔷 Problems Addressed by the PA Series
- Surface scratches and damage caused by metal fasteners
- Electrical conduction between metal components
- Variations in fastening quality during assembly
🔷 Key Features of the PA Series
- Sufficient mechanical strength for use with metal screws
- Protects the surface of mating materials
- Functions as an electrical insulator
- Lightweight and easy to install
- Optimized for washer and auxiliary component applications
🔹The PA Series is designed for protection and insulation, not for load-bearing applications.
🔷 Typical Application Industries
🚗 Automotive Electrical Systems
- Acts as a buffer between metal parts at fastening points
- Reduces electrical conduction risks
- Prevents surface damage during assembly
🖥️ OA Equipment
- Used as washers and auxiliary parts in office equipment
- Improves assembly quality and operational safety
🔌 Home Appliances
- Protects housing surfaces
- Reduces stress concentration during screw tightening
- Contributes to longer product lifespan
🔷 Suitable Usage Conditions
- When washers or auxiliary components are required alongside metal screws
- When surface protection from metal fastening is necessary
- When electrical insulation between metal components is required
- When higher mechanical strength than PC material is preferred
📘 Summary
The PA Series is a plastic component line designed to improve product safety and durability through surface protection and electrical insulation at fastening points.
It is well suited for industrial applications where long-term stability, assembly quality, and protection of components are required.
