FAQ

What size bolt or screw should I use with these washers?

The washers are designed to fit standard bolts and screws with a shank diameter of approximately 4.2mm (0.17″). They work well with M4 and #8 fasteners, but always verify the exact fit for your specific application.

Can these copper washers be used in high‑temperature environments?

Yes, copper maintains its mechanical properties at elevated temperatures up to about 200 °C (392 °F). For applications exceeding this range, consider a material specifically rated for high‑heat service.

Are the washers reusable after removal?

Because they are made of copper and have a spring design, they can be reused a limited number of times without significant loss of performance. However, for critical safety‑related applications, it is recommended to replace them after each major maintenance cycle.

How do I ensure the washers are installed correctly?

Place the washer between the bolt head or nut and the mating surface, ensuring the conical side faces the load direction. Tighten the fastener to the specified torque, allowing the washer to compress and provide the intended preload.

What is the warranty coverage for these washers?

Aexit offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues, contact our support team with the product details for a prompt resolution.
