How to choose the right size HELIFOUNER copper washer for my bolt?

Select a washer where the inner diameter matches your bolt size. For these M16 washers, the inner diameter is 16mm. The outer diameter (22mm) and thickness (1.5mm) determine load distribution and sealing capability. Ensure the washer's dimensions are appropriate for your specific application and the fastener being used.

What are the main benefits of using copper washers over steel or rubber?

Copper washers offer higher heat resistance and create a tighter seal than steel or rubber. They are also corrosion-resistant and highly conductive, making them ideal for fuel, hydraulic, and automotive applications where temperature and leak prevention are critical.

Are these HELIFOUNER copper washers suitable for use in India?

Yes, these washers are suitable for use in India. Their copper material provides good corrosion resistance, which is beneficial in humid Indian climates. All customs duties and GST are included in the price, and they are shipped via ExpressBox for reliable delivery across India.

What applications are these M16 copper washers best suited for?

These M16x22x1.5mm copper washers are best suited for applications requiring a tight seal and high heat resistance, such as sump plugs, water, fuel, and hydraulic fittings. They also prevent bolt heads from tearing through materials in industrial, automotive, and home appliance builds.

How do these copper washers prevent loosening or pressure dispersion?

The washers provide a solid bearing surface that spreads the load of the nut or bolt head over a larger area. This prevents the fastener from tearing through the material and helps to isolate vibrations, thereby preventing loosening and pressure dispersion.

What is the difference between a flat washer and a fender washer?

A standard flat washer, like these HELIFOUNER copper washers, has an outer diameter suited to distribute load under a bolt head. A fender washer has a significantly larger outer diameter relative to its hole, providing a wider bearing surface for soft materials or oversized holes.

Why choose this product

Engineered for Durability and Performance

These HELIFOUNER copper washers are crafted from high-quality copper, offering superior heat resistance and corrosion protection compared to common steel or rubber alternatives. Their smooth surface reduces friction, ensuring a tighter seal and preventing leaks in critical applications like fuel and hydraulic fittings. The M16 size with a 22mm outer diameter and 1.5mm thickness effectively spreads load, preventing damage to fastened materials and ensuring long-term reliability in industrial and automotive settings.

Ideal for Indian Conditions vs. Local Options

For Indian users, these washers are a robust choice for projects exposed to varying temperatures and humidity. While local hardware stores offer basic steel washers, they may corrode faster and lack the heat tolerance of copper. These imported washers provide a more durable and reliable seal for automotive repairs, plumbing, and industrial machinery, ensuring longevity where local options might fail prematurely.

How to use

Select the Correct Washer — Choose an M16 copper washer from the HELIFOUNER 60-piece set. Ensure the inner diameter (16mm) matches your M16 bolt or screw precisely for a snug fit.
Position the Washer — Place the washer onto the bolt or screw before inserting it through the material. The washer should sit flat against the surface where the nut or bolt head will rest.
Tighten the Fastener — Thread the nut or bolt and tighten securely. The copper washer will spread the load, prevent the fastener head from damaging the material, and create a tight seal to prevent leaks.
