Machine Screw Flat Washer

Machine screw flat washers are made with smaller outside diameters to be used with machine screws, but they are also used in many other applications where large diameters just don’t work. Machine screw flat washers feature the littlest form factor when compared with other types of flat washers due to the fact that their outside diameter is only about twice the inside diameter. Machine screw washers are utilized to ensure an even distribution of loads. This type of flat washer helps prevent damage to products and materials that can be caused by machine screws. Machine screw flat washers are most commonly supplied in low carbon steel with a zinc plating. However, these flat washers are also available in stainless steel, brass, and other materials and finishes. Screw washers are utilized to build fences, decks, and other types of products. Machine screw flat washers are supplied in varying thickness levels to meet your preferences and specifications. Choose a screw washer with a screw size, O.D., I.D., and thickness that aligns with your needs.
