Place the JEGS transfer stud punch in a quarter-turn weld plate or body panel. The slot in the back of the transfer punch fits over the existing quarter-turn spring. Position the panel over the top of the punch and lightly tap on the panel with a soft hammer to mark it for drilling of the hole. Choose from #5 or #6 sizes. Use several transfer punches to mark several locations on larger panels in order to save time. 1/pkg. .
