How to Use a Weld Nut
December 30, 2021Weld nuts are one of the most underappreciated and underrecognized industrial fastener products. Both standard spot and projection weld nuts provide an effective way to permanently attach a fastener to a metal workpiece, allowing additional fasteners or parts to be added to the initial workpiece. Weld nuts are available in several sizes and styles for a broad range of applications.
Weld Nut Classifications & Material OptionsWeld nuts are commonly manufactured from stainless steel (to enhance corrosion resistance) or low carbon steel materials. These materials allow the weld nut fastener to be protected from all types of environmental stresses, including highly corrosive salts and acidic materials with the use of 316 S.S.
Weld Nut Configurations & ClassesWhether your application requires a weld nut that can withstand light-, medium-, or heavy-duty loads, there is a configuration that provides the features that match your project specifications. The hex weld nut is suitable for a wide range of heavy-duty applications, while tab nuts are best for lighter applications.
Spot Weld NutsTab weld nuts are specifically designed to be spot welded onto flat applications. These types of weld nuts are also manufactured with a locating boss around the base threads, which assists in locating the pilot hole. When space limitation is a primary concern, tab spot weld nuts provide an effective solution that will accommodate several electrode sizes for use in a standard production/fabrication environment. Spot weld nut options include:
- Single tab
- Double tab
- Twin pilot
- Single tab with target
Projection Weld NutsTab projection weld nuts are ideal for heavier gauge materials and can be applied to flat or curved surfaces. Projection weld nuts feature a single projection that facilitates a strong and penetrating weld. Projection weld nuts are available with several projection configurations, some of which include:
- Single projection
- Dual rib projection
- Four projection
- Hex, six projection
- Square projection
