A weld stud includes a cylindrical body having an outer surface and opposing first and second ends. At least one groove is formed in the outer surface of the cylindrical body. The groove extends helically about the cylindrical body from the first end toward the second end of the cylindrical body. A thread is formed on the cylindrical body and extends longitudinally from the first end towards the second end of the cylindrical body. The thread projects radially outward from the cylindrical body.
