A washer is a small fastener placed between a bolt and a material, for example, a metallic bolt on a wood stand. Its purpose is to spread the pressure applied by the screw head across a wider area, preventing the bolt from sinking into the soft wood.
As the name suggests, a square washer is a square-shaped washer that offers the unique advantage of providing a larger bearing surface area than the standard round washer, improving performance in fastening structures.
A washer may seem like a small detail, but it plays an important role in ensuring even load distributions, balance, and long-term durability.
Load Distribution
When a bolt is under a heavy load or during heavy-duty construction, the pressure builds up in that area, which can cause damage. The larger surface area provided by a square washer helps distribute the force more, preventing the risk of material damage, like the fastener drilling through the wood.
The flat and cornered sides of the washer keeps the material fixed and prevents it from rotating, especially in corners or places where the surface area is not perfectly round. This is ideal for spaces that require specific alignment and constraints.
Their shape also means that we can safely unfasten screws without causing any damage to the material.
Balance
Thanks to their square shape, the straight edges fit pleasantly into slots, reinforcing the grip between connections in high-vibrating environments.
They prevent any basic movement or rotation, hence providing additional support and stability to the fastener components.
Durability
Square washers are made from hardened stainless steel and can withstand harsh conditions such as high humidity or temperature variations without wearing down or loosening.
They come in handy in outdoor structures like fencing and decking, where exposure to various conditions can break down fasteners.
Flexibility
Square washers are compatible with different wood densities, even treated lumber, which is coated with chemicals to resist moisture. Their design allows them to accommodate various fastener types, guaranteeing a secure connection with any material.
Due to their large surface area, they help distribute the pressure evenly, making them perfect for weak materials like wood that can expand and contract or wear over time.
Square washers provide ultimate load management and offer longevity. Minneapolis Washer & Stamping has a huge product selection and is eager to provide the highest level of service to satisfy all your washer needs.
