Did I forget a screw?

Hi,

I replaced the grease in my old KitchenAid K45SS two weeks ago. The machine works and I thought everything is right.

But yesterday, during cleaning the room, I found a small screw on the floor and I don´t know where it came from.

I thought about my KitchenAid repair and now I´m scared if I forgot one screw.

Can someone tell me if the KitchenAid K45SS Classic has such a screw, and if where did i forgot mine? (It is regular check paper so each square is 5mm. the screw has a length of ca. 1cm and the hea is about 6mm)

Thanks in advance!
