AI summary

A digital threaded plug gauge, including a barrel, a sleeve disposed around the barrel configured to move up and down with respect to the barrel, the sleeve including a serrated rod having serrations thereupon, a spring attached to the serrated rod to allow for elastic functionality of the serrated rod as the sleeve moves up and down with respect to the barrel, and a sprocket disposed within the sleeve to cause the serrations of the serrated rod to catch upon the sprocket to allow the digital threaded plug gauge to obtain a depth reading corresponding to a distance that the sleeve has traveled, a display unit to display a distance that the sleeve has traveled, and a caliper circuit board to sense a distance that the sleeve has traveled with respect to the barrel, thereby allowing the display unit to display the distance that the sleeve has traveled.
