Flat washers are thin metal discs featuring smooth surfaces on both sides. They are positioned between fastening components during assembly. The central hole in washers permits easy passage of bolts or screws and creates a secure seal upon tightening.

Flat washers help spread force uniformly across the fastener's surface, preventing damage from concentrated pressure points. They also serve as effective barriers against corrosive elements.

The most common material types for flat washers are:
Stainless Steel - corrosion-resistant and durable. Widely used in marine, food processing, and outdoor applications.
Carbon Steel - strong and durable. Used in heavy machinery and automotive parts.
Aluminum - lightweight with good corrosion resistance. Used in aerospace and automotive applications.
Copper - excellent conductor with good corrosion resistance. Used in electrical, plumbing and high-heat applications.
Brass - corrosion-resistant with good electrical conductivity. Common in electrical, plumbing and decorative uses.
Nylon - lightweight, non-conductive and chemical-resistant. Used in electrical and plumbing applications.
Rubber - provides sealing and vibration absorption. Common in plumbing and automotive uses.
