CV bolt, lock washers Options

[Elliot Cannon]

I sent to Pellican for CV bolt lock washers. I think I could have found these at the local hardware store. Are the others not available anymore. Should I trust these?

The benefi ts
of SCHNORR® Disc Springs
also known as Belleville Springs result in
design engineers continually increasing
preference for them:
1. Load/defl ection curve of straight,
progressive or regressive character,
according to the design requirements.
2. Alteration of spring performance as
desired by the addition or removal of
single discs.
3. Space saving.
4. Largely self-damping, particularly
with parallel stacking, giving good
shock absorption and energy dissipation.
5. No deformation or fatigue under
normal loads.
6. Long service life.
7. The large range of possible applications
for individual spring sizes simplifi
es stock-keeping.
