Have just installed 36 x e-clips as one sided retainers for each individual the paddle blade shaft
The shafts are Imperial as 1/8" [0.125"] drawn brass bar.....for the individual [18 in total] paddle blade shafts
So I ordered 40 x N1500 Series Code 0012 in KSF material......[being non-magnetic & non rusting].....I was hoping for a Bronze material, however they turned out to be a Grade 300 series stainless material ........the nominated e-clip grooves were .023" wide x .018" deep
There is one at each inner end of the shafts, so the first one is relatively easy to install, the second on each shaft as it is hard up against a plate......
I should have ordered 50......as 2 snapped when being installed & 2 sprang into the air....never to be seen again
With the groove dimensions being correct, I suspect questionable heat treatment of the stainless sheet that these were stamped from, as the root cause of the e-clips failure
