Welding nuts were designed and engineered to be welded to another steel object. Depending on the application, weld nuts can come in numerous sizes, shapes, thicknesses, and configurations. One overarching benefit of a weld nut is that it can be used in restricted or limited space areas after installation. The thicker design of a hex weld nut makes it ideal for heavy duty applications, in place of a tab nut that is typically used for lighter jobs.
Overall, weld nuts form the strongest bonds when compared to mechanically clinched fasteners. However, due to the necessary welding process, welding nuts are not plated for corrosion protection; subsequent painting or plating processes would be required to protect the assembly from corrosion after the welding process has been completed.

Premium Weld Nut OptionsWeld nuts are highly specialized fasteners that are designed to be welded to another object. There are numerous weld nut options to suit a wide range of applications. The different types of weld nuts, include:
Round Weld NutsRound weld nuts have a long-threaded cylinder with a large circular base to make welding easy. They also sometimes have projections (known as weld nibs or bosses) to keep the nut from warping while welding with a high current.
Slab Base NutsThese nuts are closely related to round weld nuts, but with an obround slab shaped base. They are used in channels, tubes, or other tight quarters.
Tab Base Nuts
These nuts are designed for spot welding on flat workpieces. They have a locating boss around the threads to locate it in a pilot hole.
Hex Weld Nuts
Hex weld nuts are very similar to standard square, or hex nuts, but with locating boss and welding projections. The bosses also keep weld spatter out of the threads.
Retainer Weld Nuts
Retainer weld nuts, also known as bridge weld nuts, have a floating nut retained inside a retainer to compensate for inconsistencies. The retainer is welded to the workpiece while the nut can float.
Tube End Nuts
Tube end nuts are sized to fit into the end of standard sized tubing, thus creating a threaded tube from standard stock.
Flange Weld Nuts
Hex weld nuts with flanges are designed with greater strength and are capable of meeting higher proofloads in many welding applications. Performance and weld timing are better than a standard hex weld nut due to the larger bearing surface and projection size and placement. Because of the flange, the spacing between the threads and the projections decreases the chance of getting weld splatter on the threads.
Projection Weld Nuts
Projection weld nuts provide a high torque value, allowing them to withstand heavy duty, industrial applications. Projection weld nuts are generally resistant to twisting and deforming when used in higher torque situations. These specialized weld nuts have 3 projections that melt into the host material during the welding process, allowing for a fast and secure hold.

Welding Nut Material Options
Typical weld nut suppliers offer weld nuts that are manufactured utilizing a low carbon steel with a plain finish. However, other materials, such as stainless steel, are available depending on the parent material in the application. Weld nuts are available with either inch or metric threads. As a premium weld nut distributor, JHP Fasteners serves American and European (metric, DIN style) weld fasteners.
Your specific application will dictate the fastener material, size, and design that you will need. For more information, contact us. We’ll help you select the industrial fasteners you need to complete your job right the first time.
Choosing the Correct Weld Nut
Each job you take on will require the use of different types of fasteners, depending on the specifics of the job. Choosing the correct weld nuts to complete your application depends on a wide range of factors including:
- Application type
- Parent material
- Weld nut material
- Type of welding
- Base design
