Weld Nut

Weld Nuts are specialized nuts designed to be permanently welded onto metal surfaces, providing a secure threaded connection. They are available in square, hex, round, flanged, and projection types to suit different welding applications. Manufactured to ASTM and DIN standards, they are typically produced from low-carbon or stainless steel for weldability. Weld nuts are commonly used in automotive, aerospace, furniture, and heavy machinery manufacturing. They ensure reliable fastening in thin sheet metals and components where tapped holes are not feasible.
