Furthermore, which side of nut goes down?
In my experience if you are not using pal nuts put the square side down . if you are using them put the beveled side down as the pal nut gets a better grip against a flat surface. On curved washers The beveled side goes down always.
Subsequently, one may also ask, which way do Bolts go on?
Usually clockwise. If reaching around behind, I use the right hand rule. You turn the fastener in the direction your curled fingers point and it will move in the direction indicated by your thumb.
The bevel side of the washer is facing towards the bolt head.
