Product Introduction:
Square washers are a type of washer used in wood construction and concrete floor applications, mainly to increase the load distribution and meet the structural requirements when bolts pass through walls or wood.

Specific uses:
Square washers are often used in the construction field to replace round washers in order to distribute pressure and prevent damage to the surface of the connected parts. Its structural features enable it to better adapt to the load-bearing requirements of materials such as wood or concrete.
Application field:
The application fields of square washers mainly include building steel structures, installation of new energy equipment and mechanical design, etc.
Building steel structure
The square inclined washer is used in conjunction with structural components such as channel steel and I-beam. Through the design of the inclined surface, it compensates for the angular deviation of the contact surface of the structural components, ensuring the stability of the connection.
New energy equipment
The square gasket made of 304 stainless steel can withstand salt spray corrosion environments and is suitable for the installation scenarios of outdoor equipment such as solar and wind energy.
Mechanical design
Selecting in accordance with the GB 853 standard can ensure connection reliability and is commonly seen in industrial scenarios where pressure needs to be evenly distributed.
