TOTO Toilet Hinge Screw Kit - Expanding Rubber Bolt Top Nuts Set for Top Mount Toilet Seat Tightening, Blind Hole Fixing, 2 Pack

Work great so far, easy install,fits good

These resolved my issue where I couldn’t reach inside nut to securely tighten the previous seat. These worked great! Only had to tighten the top side screw. No more plastic cheap nuts that won’t stay tight!

The project works but 1) no instructions; 2) washers that came with the package were too small and goes through the holes in the seats so I had to find bigger washers;3) at first I thought they didn’t work and was about to return them, but screwing them further eventually tightened and was strong enough to hold the seat down firmly.

Exactly what I needed. The toilet seat was wiggling, I took it apart and the rubber surrounding the screws had split. I looked and found these exact replacements and it was an easy fix!

These things are STURDY and are about 2.5 inches long. Long gone are the days of tightening the toilet seat lid every couple of weeks- I imagine these will stay tight for quite a long time since the screws are so long. These are much better than the flimsy ones they replaced, and are a great value ! Compatible with our american standard straight walled toilet.

Does exactly what it says, worked for us.

The rubber gasket did not hold at all, and slid around enough to the point where it was functionally useless. As others have mentioned the washer was also too small and had to be replaced with a larger washer. It still was not a useful product and did not firmly seal the seat to the toilet. Good in theory, not in practice.

Mine were too small and rubberized parts wouldn’t fit. Had the great idea of cutting off one of the bulbous parts. I then managed to fit it in. Using this with TOTO bidet seat.

Very good
