Distributes Fastening Pressure

A FLAT WASHER increases the contact area between the screw head or nut and the workpiece, allowing fastening pressure to be distributed more evenly across the workpiece surface and reducing excessive localized stress.

Protects the Workpiece Surface

The washer separates the screw head or nut from the workpiece, helping reduce scratches, indentations, coating damage, and deformation around the mounting hole during tightening or removal.

Compensates for Hole Size and Assembly Spacing

A FLAT WASHER can cover larger mounting holes or adjust spacing between components, making it suitable for sheet metal, machinery, furniture, and various assembly structures.

Multiple Material Options Available

Metallic or non-metallic materials can be selected according to strength, rust resistance, corrosion resistance, electrical conductivity, insulation, and weight requirements, with different surface treatments available as needed.

Wide Range of Applications

FLAT WASHERS can be used with screws, bolts, nuts, and other fasteners. They are commonly used in machinery, automotive components, electronics, home appliances, architectural hardware, and industrial equipment.
