What is the difference between copper and steel washers?

Copper washers offer superior heat resistance and a tighter seal compared to steel or rubber washers. They are also highly conductive and corrosion-resistant, ensuring greater durability and performance in applications like fuel and hydraulic fittings.

How do I choose the right size copper washer?

Match the inner diameter of the washer to the diameter of your bolt or screw. For these M16 washers, the inner diameter is 16mm, designed for M16 fasteners. Ensure the outer diameter (22mm) and thickness (1.5mm) are also suitable for your specific application's load-spreading needs.

What are copper washers used for?

Copper washers are used with nuts and bolts to provide a larger bearing surface, preventing the fastener head from tearing through materials. They help spread load, prevent leaks, isolate components, and prevent loosening, especially in applications involving fuel, hydraulics, and high heat.

Are these HELIFOUNER washers suitable for Indian conditions?

Yes, the corrosion-resistant nature of copper makes these washers suitable for India's varied climate, including humid coastal regions. They are imported and offer a durable solution for automotive, industrial, and plumbing needs.
