FAQs

What does M20 mean?

M20 refers to the metric thread size, indicating the nominal diameter of the bolt or screw is 20 millimeters.

Are these washers suitable for outdoor use?

They can be used outdoors, but carbon steel is prone to rust. For long-term outdoor applications where exposure to elements is high, consider galvanized or stainless steel options.

Can I use these with a bolt smaller than M20?

No, these washers are sized for M20 bolts. Using them with smaller bolts will result in excessive play and reduced effectiveness.

How many washers are in a pack?

Each pack contains 50 flat washers.

What is the primary purpose of a flat washer?

A flat washer is used to distribute the load of a threaded fastener, such as a bolt or nut, over a larger surface area, preventing damage to the material being fastened and helping to prevent loosening.

What material are these washers made from?

They are constructed from durable carbon steel.

Troubleshooting

Washer does not fit on bolt

Ensure the bolt is indeed M20 size. These washers are only compatible with M20 hardware.

Rust spots appearing on washers

Store washers in a dry location away from humidity. Minor rust can often be cleaned with a wire brush and the area protected.

Washer feels too thin for the application

While designed for load distribution, consider thicker washers or alternative materials if extreme pressure is expected.
