nut and bolts

Start at the left

Schematically with note.

I have seen a lot of questions but this one takes the cake.

and the answer is.....

Method-1

1. Take all the nuts in this thread (starting with the OP or may be that is the only one)

2. Check its thread starting from the root (may find some thing interesting over there)

3. Make a circle around its pitch and check its diameter. You may take some small pins to stick around it for convenience.

4. Find its inclination and slope.

5. Use suitable apparatus for making the drawing.

Method-2

1. Walk into the open while the weather is just suitable.

2. Stick a long metal rod into the ground pointing up. Minimum length 4 meters

3. Log into it with your notebook/Laptop.

4. Wait for the lightning to strike.
