Weld nut designs are based on size, shape, thickness, and configuration. These industrial fasteners are welded onto another metal piece and can bridge gaps or seams. A weld nut is able to be used in restricted or limited space areas. The hex weld nut design is ideal for heavy duty applications whereas a tab nut is typically used for lighter jobs. A right-angle weld nut attaches to the parent material and creates a threaded hole vertical to base material.
Weld Nut Types
A weld nut is a highly specialized type of fastener nut that is designed to be welded to another object. Furthermore, weld nuts are made with a greater amount of material than other nuts, so their form is maintained after being 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 Nuts – Round 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 Nuts – These 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 flange weld nuts are lighter than weld nuts with similar strengths.

Choosing the correct weld nuts to complete your application depends on various factors including:
- Application type
- Parent material
- Weld nut material
- Type of welding
- Base design
JHP Fasteners, the Leader of Weld Nut Suppliers
Weld nuts from JHP Fasteners are available in many configurations including hex, round, slab, and tab base weld nuts. The hex weld nut design is ideal for heavy-duty applications whereas a tab nut is typically used for lighter jobs. A right angle weld nut attaches to the parent material and creates a threaded hole vertical to base material. Metal weld nuts have a critical design in that accurate pressure and current must be used during the welding process to secure optimal performance in aftermarket use.
Typical welding nuts are manufactured in a low carbon steel with a plain finish. However, other materials, such as stainless, are available depending on the parent material in the application. Weld nuts are available with either inch or metric threads. JHP Fasteners distributes American, European, and American metric fasteners.
