TEC-MEC Iron Square Washers 30-45mm

A square washer is a type of washer with a square shape, commonly used in various mechanical and structural applications. Unlike the more common round washers, square washers provide a larger surface area to distribute the load evenly across the surface they are placed on. This can help prevent damage to softer materials and ensure a more secure connection.

1. Shape: Square washers have a square shape, providing better contact with the material, especially in cases where the fastener (like a bolt or screw) has a square or rectangular hole.

2. Material: Square washers are usually made from the same materials as standard washers, such as steel, stainless steel, zinc-coated steel, brass, and plastic. The material selection depends on the application, environment, and load requirements.

3. Size: They come in various sizes to fit different bolt or screw sizes. The size is typically defined by the outer dimensions of the square, and the hole size in the center, which is designed to fit the corresponding bolt or screw diameter.

4. Load Distribution: Square washers provide a larger bearing surface than round washers, which can help to distribute the load more evenly, reducing the risk of the material being damaged.

1. Standard Square Washers:

   • These are flat washers with a square shape and a central hole for the bolt or screw. They are primarily used to distribute the load evenly over a larger area than a round washer.

2. Square Tapered Washers:

   • These washers are designed with a tapered edge and are often used in applications where the load needs to be distributed more efficiently across a joint or surface. They can also help to prevent loosening over time.

3. Square Plate Washers:

   • Larger square washers that act as plate washers, often used for heavy-duty applications, like securing large steel plates or securing bolts in construction or machinery.

1. Woodworking and Furniture:

   • Square washers are often used in woodworking to distribute the load of screws or bolts and prevent the material from being crushed or deformed.

2. Construction and Engineering:

   • They are used in construction to reinforce connections in steel structures, concrete, and wood, ensuring a more secure fastening with better load distribution.

3. Electrical Equipment:

   • Square washers are sometimes used in electrical equipment and enclosures to secure components to panels or provide grounding connections.

4. Automotive:

   • In automotive applications, square washers are used to provide better stability and load-bearing capacity for various fasteners in suspension systems, machinery, or bodywork.

5. Machinery and Industrial Equipment:

   • They are often used in machinery for securing parts together, such as in engines, assembly lines, or conveyor systems, especially when large forces are applied to the fasteners.

1. Better Load Distribution: The square shape helps distribute the load evenly across a larger surface area compared to round washers.

2. Increased Surface Contact: The larger surface area provides better friction and can prevent damage to the material being fastened.

3. Prevents Pull-Through: In softer materials (like wood or plastic), the larger contact area helps prevent the bolt or screw from pulling through.

4. Better for Square or Rectangular Holes: They are particularly useful when the material or fastening component has a square or rectangular hole, providing a better fit than round washers.

Square washers come in a variety of sizes, and the size is typically chosen based on the bolt or screw size. Here are some typical measurements:

• Small Sizes: For smaller bolts or screws, you might find square washers ranging from 10mm x 10mm to 25mm x 25mm.

• Larger Sizes: For larger bolts or industrial applications, square washers can range up to 100mm x 100mm or more.
