mechanical assembly

hi guys as I have to face the industrial technical drawing exam I was practicing in view of the graphic test (to be done manually and not to the computer). In this regard I wanted a few tips on a total, in particular I do not understand what type of screw is component 6, same problem for the dice 7 from which I can not get the other views. Finally I would like to understand how they present on another view the recesses for the rings or.

Thanks to anyone who wants to help me!

# 6 = headless hexagon screw uni27434

#7 = is a nut with a cap, but looks like a special, unified. However, what you don't say is just the hexagon, for the rest it's definitely a solid revolution so you can model it from view 2d.
