Square flat washers are commonly used in mechanical equipment and industrial equipment, wood structures, decoration, electrical, automotive industrial applications, construction, pipelines, etc. Square washers provide a larger contact area for fasteners, provide higher load-bearing capacity and higher stability, can reduce friction and prevent loosening.

Specification ：
Material: Carbon Steel
Size: 9x18 mm / 0.35x0.71 inch ( Inner diameter x width )
Thickness: 2mm
Height:5 mm / 0.2 inch

Advantages:Square washers are made of rust-proof and corrosion-resistant Carbon Steel. They have excellent heat and low temperature strength, good oxidation resistance, durable, not easy to break or deform, suitable for indoor and outdoor use.

Instruction :The beveled edge of the washers is designed to wedge and level uneven surfaces, making them suitable for shim leveling and adjustment. Beveled square washers create a more stable surface, they keep the thrust faces parallel, preventing bolted joints from shifting.
