I lost the Winco RW-S450 Nut that holds the pin in place so in turn it can hold the lid.
After going to Lowe’s I found the perfect nut size for it. It is M4-0.7 Metric; I bought these 2 pack at Lowe’s.
It goes on the other end of the pin. FYI, the metal pin is not sold by Winco. I have already asked Winco Customer Support.
