Description

Electrical & Thermal Insulation

Standard metal washers conduct electricity and heat, which can lead to catastrophic shorts on printed circuit boards or terminal blocks.

Nylon is a natural insulator. Using these washers gives you the practical advantage of a completely safe, non-conductive barrier, ensuring your sensitive electrical and electronic installations remain fully protected.

Ultimate Surface Protection

Tightening a steel washer against soft plastics, glass, painted metal, or finished wood often results in cracking or deep scratches.

The slightly compressible nature of high-grade nylon evenly distributes the clamping load without biting into the substrate. This guarantees a secure, flush fit while preserving your delicate and decorative finishes.

Vibration & Noise Dampening

Metal-on-metal joints can rattle loose or generate unwanted noise under continuous vibration.

Nylon naturally absorbs shock and dampens vibration, making these washers ideal for automotive interiors, HVAC equipment, and moving machinery where a quiet, secure, and rattle-free assembly is completely essential.

Prevents Galvanic Corrosion

When you fasten two different metals together (such as a stainless steel bolt into an aluminium panel), an electrical reaction can cause rapid corrosion.

By placing a non-conductive nylon washer between the dissimilar metals, you instantly break the electrical circuit, preventing galvanic corrosion and drastically extending the lifespan of your hardware.

Frequently Asked Questions

Why use nylon instead of a rubber washer?

Nylon is significantly harder and more rigid than rubber. This means it can withstand higher clamping forces without flattening out completely or perishing over time, while still providing excellent surface protection and electrical insulation.

Will these washers stop my assemblies from rusting?

The washers themselves are completely immune to rust. Furthermore, if you are joining two dissimilar metals, using a nylon washer between them stops the electrical reaction that causes galvanic corrosion, protecting your entire assembly.

Can I use these for high-temperature engine parts?

No. While high-grade nylon is highly durable for everyday applications, it will melt or deform under extreme heat. For high-temperature automotive applications (like exhaust manifolds), a copper or specialized heat-resistant metal washer is strictly required.
