When we use the screw and put it into a wall we rotate it to the clock wise
A screw gauge works on the principle of screw. This screw principle helps to convert smaller distances into larger ones by measuring the rotation of the screw. It amplifies the smaller dimensions and this converts into larger ones. When we rotate the screw, there's a linear movement of the main scale.

The most common means is by use of a spiral. Think of a long screw and a nut.
