Square Washers, as the name implies, feature a square-shaped body with a central circular hole designed to accommodate bolts or screws. Compared to standard round flat washers, square washers offer a greater surface area, which enhances load distribution and friction during tightening. Their larger footprint makes them especially suitable for structural and seismic applications where added stability is critical.

Adfast Component manufactures square washers in a variety of metric and imperial sizes, providing extensive material options and customizations to meet diverse industry needs. Common materials include zinc-plated steel, stainless steel, and hardened alloy steel, ensuring both strength and durability in demanding environments.
