FAQs

What material are these washers made of?

These washers are constructed from durable carbon steel.

What size bolt or screw do these washers fit?

They are designed to fit M4 size bolts and screws.

How many washers are in a pack?

Each pack contains 10 large flat washers.

Can I use these washers for outdoor projects?

Yes, but for prolonged outdoor exposure, especially in damp conditions, it is recommended to apply a rust-inhibiting coating or oil to prevent corrosion.

What is the primary function of a flat washer?

A flat washer's primary function is to distribute the load of a threaded fastener, such as a screw or nut, over a larger surface area, preventing damage to the material being fastened and ensuring a more secure connection.

Are these washers hardened?

While constructed from carbon steel for durability, the product information does not specify if they are hardened. They are suitable for general DIY applications.

Troubleshooting

Washer does not fit on the bolt.

Ensure you are using an M4 bolt. This washer is specifically designed for M4 size hardware.

Washer shows signs of rust.

This is typical for carbon steel if exposed to moisture. Clean lightly with a wire brush and apply a protective oil or coating for further prevention.

Washer deforms under pressure.

Ensure the load is being distributed evenly. If the force is excessive for an M4 fastener, consider using a larger bolt size or a washer made from a stronger material.
