Weld Nuts

Weld nuts are known for their welded base (including three or six equidistant welded projections and a long or short collar pilot), which allows seamless integration to metal surfaces via the welding process. 

Frequently Asked Questions About Weld Nuts

What are weld nuts used for? 

Weld nuts are most frequently used in applications where conventional fasteners may not suffice. This commonly means use in conjunction with metallic components, such as in automotive manufacturing, industrial machinery, and structural steel construction.

What are the advantages of using weld nuts? 

There are several significant advantages associated with using weld nuts, including secure attachment, enhanced structural integrity and reliability, corrosion resistance, compatibility with various welding techniques, and use with diverse metal thicknesses and configurations. 

What is the difference between a weld nut and a rivet nut? 

The main difference is found in how they attach to metal: weld nuts are fused to the metal using a welder, whereas a rivet nut is clamped onto a pre-drilled hole. 

What sizes do weld nuts come in? 

AFT offers weld nut sizing in both metric and SAE standards. Diameter-thread sizes range from 1/4”-20 to 1/2”-13, or M3-0.50 to M16-2.00. 

What materials and finishes are available for weld nuts? 

Weld nuts are available in plain steel or stainless steel.
