Here I will tell you about 3dsmax 3d model nuts studio tutorial. I have used following techniques in this 3ds max tutorial. Editable poly and shell modifier techniques.
Cylinder Radius: 50,0 Height: 240,0 Cap Segments: 2 Sides: 24
This will be the base we can copy several times to get the whole bolt. Duplicate it once and move it 1.52 in the z-axis. You'll see that the duplicate lands exactly where the other stops.... Why is that? Because the height of the helix is 1.52 :)
