Hex Weld Nut
Click image to enlarge
Standard hex weld nuts are available in short and long projection. The projection refers to the raised feature on the nuts that connect with base material during welding. Short projections offer many advantages such as reduced heat impact which reduces the risk of damage during welding and quicker installation time. Long projections offer other advantages such as increased strength and alignment due to greater welding surface area compared to that offered from short projections. A user will need to consider the mechanical stress and space constraints to select the best option for the application.
