Weld Nuts

  • CAT 67

Weld nuts are designed and engineered to be welded to another metallic object, providing high strength fastening capabilities in restricted or limited space areas. Weld nuts are available in numerous sizes, shapes, thicknesses, and configurations. Depending on the application, welding nuts can be sometimes be used as a substitute for standard mechanically clinched fastener products. The generally 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.

Weld nuts form extremely strong bonds. 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.

For more information on our weld nut product options, get in touch with our sales team or call us at 800-783-0910 and we will gladly discuss your project needs. JHP Fasteners is your trusted provider of premium quality welding nuts and advanced fastener products.


Premium Weld Nut Options

Weld nuts are highly specialized fasteners that are designed to be welded to another metal object. There are numerous weld nut options to suit a wide range of applications. At JHP Fasteners, we provide a broad range of weld nut options for your project needs.

Round Weld Nuts 

Round weld nuts have a circular base with weld projections to make welding easy.

Square, Projection Weld Nuts

Square, projection weld nuts are equipped with four large, uniformly shaped weld projections that ensure exceptionally strong and reliable welds.

Tab Spot Weld 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.

Tab Projection Weld Nuts

Tab Projection Weld Nuts can feature single or multiple projections which facilitates a weld that is both strong and penetrating. These weld nuts are particularly well suited for use with heavier gauge materials and can be applied to flat or curved surfaces.

Hex-3 Projection Weld Nuts

Hex-3 projection (both low carbon mild and stainless steel) weld nuts ensure reliable surface contact during the welding process, even if that surface is not completely flat. The pilot accurately locates the nut in the pilot hole and keeps the nut on center. These weld nuts feature great torque out strength/resistance and can be utilized for a wide range of applications. 

Hex-6 Projection Weld Nuts

This hex-shaped Projection Weld Nut is equipped with six, large, uniformly shaped, weld projections that ensure superior contact with the weld surface. These are available with three different pilot heights that accommodate a variety of base material thicknesses

Flange Weld Nuts

Hex weld nuts with flanges are designed with greater strength in mind and are capable of meeting higher proofloads in many welding applications. Performance is often 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 is increased with decreases the chance of getting weld splatter on the threads. 

Stamped Flange Weld Nuts

Stamped flange weld nuts are specifically designed to be welded onto another metal surface into properly sized holes. The specialized round and slab base flange weld nut design helps overcome problems associated with other welded nuts.

Floating Cage Weld Nuts

Floating cage nuts are specifically manufactured with a floating nut that is held within a cage or retainer design to allow off-center or misaligned screws to be installed.

What are 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.

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

The Projection Weld Nut Installation Process

Projection weld nut installation is comprised of three distinct components. First, the nut with its projections is placed in contact with the sheet metal it will be welded to. Then the current and force are applied almost simultaneously but within a specific time frame. This causes the now super-heated projection to collapse rapidly under the pressure and fusion with the base metal takes place. Once the hex weld nut’s welding cycle is completed, the weld nut and substrate will not be able to be separated without destruction of the workpiece.
