Abstract
A tube and method for sizing the effective inside diameter of the tube to a smaller effective inside diameter is provided. The method uses rollers that apply focused pressure to the tube to create a crease that reduces the effective inside diameter without substantially changing the outside envelope of the tube. The crease may be either a radius or squared. Reducing the effective inside diameter of the tube creates radiused surfaces for a self-tapping screw to cut threads.
