Square Weld Nut
Square weld nuts are internally threaded fasteners with a four-sided profile, designed for secure welding onto metal surfaces. Commonly used in automotive, construction, and heavy fabrication, their flat base and large contact area ensure strong weld integrity. Ideal for applications requiring durable, fixed-thread points, they offer excellent resistance to torque and vibration after installation.
