Front sprocket lock washer direction

I went to change my chain and sprockets, only to find that the retaining nut and lock washer were both missing from the front sprocket.
I ordered the parts, but I'm not sure which direction the washer is supposed to face. Are those flanges supposed to face inward toward the shaft, so that when the nut is tightened down on top of it they bend and apply pressure against the nut? That's what I would assume, but they seem fairly pronounced, and they're also not evenly distributed around the circumference. I wasn't sure if they would be serving a different purpose by facing outward.

Re: Front sprocket lock washer direction

they go out. so after you torque the nut to spec you bend it down over the nut. you will need a big set of adjustable pliers. you only need to bend one of them down to touch the nut. you want to bend it down to one of the flat areas. don't bend it around the corners.
