you would have to recut the groove to suit the square sides.
Some do have circlips but usually small engines
What square side's are you speaking of ?Quote:

Old outboards had stamped ones and you used circlip pliers to install/remove them
they are wire now so more tension and lighter
Stamped steel type, require's piler's to install or remove.Quote:

I think he's right ... retaining holes for wire are likely round, like the wire ... they may not allow the flat side and squared top shape of the stamped steel type to properly seat.
Ok I see your point! square sided ring vs. round mechined groove.Quote:

What you are calling a snap ring is commonly called an "E" clip and todays circlips are known as "C" clips, and the C is cheaper to make as well as the holding capability is really no different, and yes the E clip reqires a groove with sharp corners which is harder to maintain than the rounded corner groove used by the C clip.
Basically the C is cheaper and easier to manufacture and works just as well, sometimes better as gravity holds the wrist pin down and the chamfer of the pin will get down on the clip and then it really can't come out
In the serious old days of racing, in the '40s and '50s, we used aluminum buttons. Later, formica buttons. But when we started using "fly-weight" wrist pins, we had to use wires, because the edge of the pin was too small, because the ends of the pin had tapered holes.
Wires work.
