2.Nuts/washers
a.Use a flanged hex nut.
b.Use washers on both the bolt head and the nut side. This is to provide clearance for the bolt head fillet and to provide greater stress equalisation and transfer through the spacer.
c.Use a spring washer on the nut side, between the flat washer, and the nut..
d.Ensure, like the bolt, that the nuts/washers are corrosion resistant (again, Magni 560/565).
e.Ensure it is also Grade 8!

Helical spring washers (I'm assuming that's what you're referring to) are actually worse than just using a nut. Testing has shown they actually contribute to fastener loosening.
Junker test results.
Helical Spring Washers
If you want to lock a fastener you'd be better to omit the spring washer and use loctite, self locking nut or nord-lock washers.
