What Are Plastic Fasteners?｜Key Advantages and Materials of Plastic Hardware

Plastic fasteners are lightweight, non-conductive, and resistant to rust and chemicals—making them ideal for electronics, medical devices, and industrial machinery. Learn the core strengths and best-use materials in this guide. 1. What Is Plastic Hardware? Plastic hardware—commonly known as plastic fasteners—includes screws, nuts, washers, and related components made from engineering plastics rather than metal. These are used in industries such as electronics, medical devices, chemical processing, and precision equipment. Plastic fasteners offer key benefits over metal: they do not conduct electricity, resist corrosion, and weigh significantly less. These features make them essential for applications that demand insulation, non-magnetic properties, and reduced weight. 2. Key Plastic Materials and Their Properties - PPS (Polyphenylene Sulfide) Excellent chemical and heat resistance. Ideal for semiconductor systems and chemical plant machinery. - PC (Polycarbonate) Transparent and impact-resistant. Used in visible or safety-critical parts of medical and electronic equipment. - PA (Polyamide/Nylon) Strong and abrasion-resistant. Widely applied in general machinery, though it can absorb moisture, which affects precision. - PEEK (Polyether Ether Ketone) Withstands temperatures up to 250°C and harsh chemicals. Perfect for aerospace, high-end medical tools, and ultra-precision components. 3. Strengths of Plastic Fasteners - Lightweight – Lowers total system weight and boosts energy efficiency - Electrical Insulation – Safe for sensitive electronics and circuit boards - Chemical Resistance – Performs in harsh chemical environments - Non-Magnetic – Prevents magnetic interference in precision instruments - Corrosion-Free – Suitable for outdoor or humid environments 4. Important Usage Considerations - Lower tensile strength and torque vs. metal counterparts - Heat resistance depends on plastic type—critical for material selection - Some types (like Nylon) absorb moisture, affecting dimensions - Susceptible to UV degradation if not UV-stabilized for outdoor use 5.

How to Install Plastic Screws (PEEK/PTFE) ｜ Tips to Prevent Deformation

Plastic screws made from high-performance materials like PEEK, PTFE, and PPS require careful installation to avoid deformation and ensure long-term structural integrity. This article offers essential industrial tips including torque control, hole dimensioning, and tool selection — especially for electronics, cleanroom, and chemical plant applications. 1. Why Do Plastic Screws Require Specialized Installation? Unlike metal fasteners, plastic screws offer chemical and heat resistance but have lower mechanical strength and elasticity. Improper installation may cause cracking, deformation, or failure — leading to reduced structural stability. Common materials include: - PEEK (Polyether Ether Ketone) - PPS (Polyphenylene Sulfide) - PTFE (Polytetrafluoroethylene) - PVDF (Polyvinylidene Fluoride) These materials excel in corrosive, cleanroom, and high-temperature environments, but require precision fastening techniques. 2. Use the Right Tools and Torque Settings Over-torqueing is one of the leading causes of plastic screw failure. Tips: - Use adjustable torque screwdrivers (manual or electronic). - Refer to the torque chart provided by the screw manufacturer. - Avoid high-RPM electric drivers unless equipped with torque limiters. 3. Maintain a Controlled Installation Environment Temperature and humidity impact plastic screw behavior. Tips: - Ideal installation temperature: 20°C–30°C - Avoid oils, chemicals, or lubricants on screw surfaces. - Store screws in a dry, temperature-stable area and inspect for warping before use. 4. Ensure Proper Pilot Hole Dimensions The pilot hole determines how the screw engages with the material. A misfit can lead to excessive stress or loosening. Tips: - Follow manufacturer’s exact pilot hole diameter. - Deburr the hole and clean it thoroughly. - For repeated assemblies, use metal inserts (threaded bushings) to preserve the integrity of the housing. 5. Avoid Over-Tightening — Apply “Just Enough” Torque Over-tightening damages the thread or head, especially in brittle or thin plastic parts. Tips: - Use a torque + angle method for consistent results in production environments. - Watch for visual cues: screw head distortion means you’ve tightened too much. - Use washers to evenly distribute clamping force. 6.
