Many thanks to Derek Job for pointing out the very interesting Bolt Science
site!
Have to say, though, the original Healey lock washers with the barb on the
end _do_ seem to work. Loosening them makes an audible snap when the nut
breaks loose and the barb digs in to the nut. Springwise they look as good
as new - seem to be made of very high quality steel.
On the other hand, the split ring lock washers on my Toyota trans are
totally flat and appear to be completely worthless.
Am curious how other lock washers - such as inside & outside stars and
belleville & wave washers - hold compared to split rings. Didn't see any
discussion of those on the Bolt Science site.
FWIW - I've used bellevilles on my front upper shock bolts for several years
and they've never loosened. I also use them on any aluminum and on the rear
axle pumpkin with rubber o-rings underneath to prevent leakage.
