If we look to modern engines we can see that lockwashers are being used 
less and less as understanding of their minimal benifits comes to light. 
Rod caps, crank mains, and even transmission pans (yes, a gasketed 
joint), no longer have lockwashers on them because they tear up the base 
metal when removed, and because they are completely unnecessary to keep 
the bolted connection tight.

Gastonia, 
I have a small collection of square head fasteners here. I have a square nut 
that is convex on one side with no flat area at all. The corners are slightly 
rounded and the 'flat' side is concave. No place for a lock washer on the top 
which is  not suitable for a bearing surface at all.
I got a 5/16 square head bolt and nut. The nut is flat on the bottom and 
rounded on the corners on the top side with a bearing area. Just like a modern hex 
nut. The bolt head is identical with the exception that there is to hole in 
the center, just flat with beveled corners and a raised letter 'E' . Nice place 
for a bearing surface but no way to make something  bear on it except maybe a 
die with a female 'E' in it.
Maybe some vendors just have better nuts than others.
Remember when they were called bolts and burrs?
