pst 1" torsion bars

My understanding is that the bars are built with a certain amount of twist into them. In this case the twist is 20*, meaning if you lay the bar on a flat surface and look down its length, placing the hexagonal end closest to you on a flat side you will see that the hexagonal end furthest from you is rotated, twisted or (clocked) 20* from the end closest to you.

Someone keep me honest here.
