Thread Type: Square weld nuts typically feature a threaded hole, enabling the use of bolts or screws for secure fastening. They can be manufactured with various thread types, such as UNC (Unified National Coarse) or UNF (Unified National Fine), to meet specific application requirements.
Welding Projections: Square weld nuts have projections or raised areas on one side, which provide additional surface area for welding. These projections help create a strong and reliable weld connection between the nut and the metal structure.
Materials: Square weld nuts are commonly made from materials like stainless steel, carbon steel, or alloy steel. Material selection depends on factors such as the intended application, load-bearing requirements, and environmental conditions.

Benefits of Square Weld Nuts

Square weld nuts offer several benefits when used for fastening metal structures:

Strong and Secure Connection: Square weld nuts provide a robust connection when welded to metal structures, ensuring high strength and reliability. The weld creates a permanent bond, preventing loosening or separation under heavy loads or vibrations.
Ease of Assembly: Square weld nuts simplify the assembly process, reducing the time and effort required for fastening. Their square shape allows for easy alignment, enabling straightforward installation and welding.
Increased Load-Bearing Capacity: The welding projections on square weld nuts enhance load distribution and increase the load-bearing capacity of the joint. This is particularly important in applications where high strength and resistance to shear or tension forces are required.
