Square OD Washers | Square Plate Washers

Square OD Washers are offered for applications where a round washer might not work. Square washers have a larger surface area than round washers with the same outside diameter. The larger surface area on square washers spreads loads over a larger area and also increases resistance. Stainless steel square washers are utilized to protect surface finishes and spread loads in a fastener assembly system that utilizes square headed fasteners.

Square plate washers are able to gain a lot of friction when applied to wood, which is why they are utilized for seismic projects and applications. Square washers are engineered to prolong the life of parts and are utilized to control sound levels and motion such as vibration. In addition, square washers can be utilized to reduce electrical current. This type of washer is broader and thicker when compared to a majority of round washers.

This part can be inserted into channels and slots to meet the requirements of your application. Square OD washers are useful in timber construction, automotive projects, and with machinery. Square washers are designed to eliminate rotation issues and fit in small spaces that are not compatible with round washers.

Types of Materials

These square plate washers are usually made from low carbon steel, but other materials are available. Square OD washers are also available in stainless steel, brass, spring steel, aluminum, copper and many non-metallic materials. We offer stainless steel square washers in various types of finishes to meet the guidelines of your project. Stainless steel square washers are resistant to chemicals and salt water.

If you are looking for square washers that are resistant to deterioration in wet environments, we recommend purchasing washers with a zinc finish. On the other hand, black-oxide steel washers are resistant to deterioration in dry environments. Galvanized steel washers feature a higher resistance to corrosion when compared to washers with a zinc finish.

Square washers or square plate washers are available in finishes such as black oxide, nickel, zinc & clear, phosphate & oil, zinc & yellow, and galvanized. Square washers are available in a variety of bolt sizes and thicknesses to ensure compatibility with your application. Willie Washer also offers other types of washers such as Slotted Square, D Shaped ID, and Wave Spring.
