Plastic Nylon Flat Washer Plane Spacer Insulation Gasket Ring for Screws M1.5–M12

Plastic Nylon Flat Washer Plane Spacer Insulation Gasket Ring for Screws M1.5–M12

Nylon plastic flat washers for electrical isolation, PCB assembly, and precision mechanical spacing. Non-conductive nylon prevents galvanic corrosion between dissimilar metals and provides electrical isolation between fasteners and sensitive PCB components. Lightweight and chemically resistant, nylon washers are the standard choice for electronics assembly and general-purpose insulating applications.

Key Specifications

Why Choose Nylon Flat Washers?

• Electrical isolation — non-conductive nylon prevents current flow between fastener and PCB or chassis
• Galvanic corrosion prevention — isolates dissimilar metals (e.g., steel screw on aluminium chassis)
• Lightweight — significantly lighter than metal washers; ideal for weight-sensitive electronics assemblies
• Chemical resistance — resistant to oils, fuels, and most solvents
• Wide size range — M1.5 to M12 covers all standard electronics and mechanical assembly sizes

Typical Applications

• PCB mounting isolation (between screw head and PCB surface)
• Electronics enclosure assembly (isolating steel screws from aluminium panels)
• Precision instrument and sensor mounting
• Battery terminal isolation and insulation
• General mechanical assembly requiring electrical isolation
• 3D printer frame and electronics assembly

Compatible With

M1.5–M12 metric screws and bolts. Compatible with DIN125 flat washer dimensions. Suitable for use with: PCB mounting screws, electronics enclosure fasteners, Arduino/Raspberry Pi mounting hardware, and general metric fasteners requiring electrical isolation.

FAQ

Q: What is the difference between nylon and PVC insulating washers?
A: Nylon (PA66) has higher mechanical strength, better temperature resistance (80°C vs 60°C for PVC), and better chemical resistance. PVC is more flexible and transparent. For most electronics applications, nylon is the preferred choice.

Q: Can I use these outdoors?
A: PA66 nylon has moderate UV resistance. For long-term outdoor applications, UV-stabilized nylon or PTFE washers are recommended.
