Comfort Seats C1B4E2-00WP Deluxe Molded Wood Toilet Seat with White Hinges, Elongated, White

I used these for six months and the hinge nuts broke off on two out of three seats. So, I went to my local home improvement store and bought the "universal" replacement nuts. They did not fit. So, I took the whole seat in and it turns out that it was a metric size. So, bought the metric stainless steel nuts home to reattach. Unfortunately one of the bolts was metric 10 and the other was a different size. In the process, the whole hinge attachment broke off and bent. So, it was cheap at the time $15. But I guess I got what I paid for.
