Hi all,
Star Washers - Push Nut - Internal Tooth Lock Washer - Tooth Lock Washer - Plum Clamp Flange Shaft Positioning Meson Push On Fasteners Locking Speed Clips .

A lot of the time they snap when removing,I think they are a good idea so spare parts makes more money, not really made to be reused,I know you
can reuse them if you are not willing to buy replacements,they are about 62 cents each.
