High Qulity DIN436 Square Washer Customized Zinc Plated Washer

The distinguishing characteristic of a square washer is its square, rather than round, outer profile.

This square shape contrasts with the more common circular washers.

Square washers typically have a circular or square-shaped hole in the center to accommodate the fastener (bolt, screw, etc.).

The hole size corresponds to the diameter of the fastener.

Square washers are commonly made from steel, stainless steel, or other metals.

They may also be made from engineering plastics or composites in some applications.

The thickness of square washers can vary, typically ranging from very thin (e.g. 0.5 mm) to relatively thick (e.g. 3-5 mm).

Thicker washers provide more support and load distribution.

Square washers are often used in construction, machinery, and industrial applications.

They can be used to distribute the load under the head of a fastener or to prevent the fastener from pulling through the material.

Common uses include securing structural elements, machinery mounts, electrical equipment, and more.

The square shape can provide more surface area contact compared to a round washer, improving load distribution.

Square washers can be easier to align and position than round washers, especially in tight or constrained spaces.

The square profile can also help prevent the washer from rotating when the fastener is tightened.
