Washers come in all manner of shapes. However, the two most common ones include the square and the rectangular washers. In some ways, they are similar and work to distribute load.
But while that’s true, these two also differ, especially regarding application. Here, we’ll discuss the differences between square and rectangular washers.
Difference in Shape
As the names suggest, these two fasters differ in shape. Square washers are square-shaped plates, while rectangular washers are rectangular. They both have larger surface areas than regular disk-shaped washers, but rectangular washers have a longer length due to their shape.
Difference In Application
Square washers are ideal for tight spaces with little room for movement. The flat side of the washer flashes squarely against the flat surface and creates a grip. Usually, these are the washers you will see in aircraft exhaust manifolds.
They are also used in other areas, such as:
- Sea Water Equipment
- Off-Shore Oil Drillers
- Spiral Welded tube for flues and burner pipes
- Gas Processing
- Pharmaceutical Equipment
- Power Generation
- Specialty Chemicals
- Heat Exchangers
On the other hand, rectangular washers are more popular in heavy-duty applications where there is more load to hold. The longer length of the rectangular shape provides more support for a heavy load that is distributed further from the fastener.
They are also helpful when fastening in areas with large holes. The rectangular, longer surface area helps cover the spaces while allowing the fastener to secure the joint. Additionally, they help prevent damage to soft materials.
For example, square washers can dig into soft material such as wood when tightened too much. Rectangular washers protect the surface. They spread out the force and decrease the chance of damage, hence why they are popular in woodwork and carpentry. Other uses for rectangular washers include:
- Construction
- Automotive Industry
- Structural Steelwork
- Heavy Machinery
- Pipelines
