Spread the load

A washer under the screw head spreads the clamping force over a larger area. That protects soft or thin parts, such as plastic fan frames or acrylic panels, from being dented or cracked when the screw is tightened.

Space and protect

A washer also covers an oversized hole, and it can add a little spacing where a screw is slightly too long for its hole.

Black to match

The black finish matches our black screws and nuts, so the hardware stays dark in a black build.
