Welding Nuts. They come with small three leg projections which are used to weld the nut into the material. These 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. These are used in channels tubes or other tight quarters. Structural nuts are typically heat treated so welding to them could cause issues and loss of strength.
Choose from a wide range of sizes and styles including round piloted weld nuts tab bases with offset holes or projections hex projections and more.
T-Nuts also known as Tee Nuts or Weld Nuts come in two broad types. Prevailing torque nut with metal insert is designed in accordance with engineering basic principal. This article examines recent experiments with projection welding of those components to various high-strength steel components. HS boltsnuts are heat treated to achieve their strength and when you weld on them you have a really good chance of destroying that heat treat plus weldability can be a problem along with crack potential.
