Self-tapping screw with an improved thread design

A self-tapping screw with improved thread design comprising:

• a head;
• a screw body extending from said head, said screw body forming a point at an end opposite said head;
• a first thread being formed around said screw body from substantially said head to a tip, said first thread turning to become substantially parallel to a length of said screw body at substantially said tip;
• and
• a second thread having the same pitch as said first thread, said second thread being formed between said first thread, said second thread turning to become substantially parallel to the length of said screw body at substantially said tip, said second thread having a major diameter which is less than the major diameter of said first thread for substantially the length of the first thread, the major diameter of said second thread equalling the major diameter of the first thread for at least one thread from said head.
