Toilet Seat Hinge Bolt Screws 4 Pack Toilet Seat Top Fixing Part Expanding Rubber Bolts with Metal Washers

Worked great. It was tough at first trying to get them in.

This hinge kit was the perfect fix for my Kohler Swiss Madison toilet seat cover after one of the original hinge screws rusted and broke. Easy to install. Push in the black plastic piece first and then insert the screw. The seat cover is now secure again. (Note: I didn't need to use the white plastic ring for my installation).

Bought this a couple months ago, and I have to say my toilet seat has not moved at all. Great product

These worked great for me. They fit tightly enough that it was a bit of a task getting them inserted, then once tightened they're rock solid. The supplied washers are too small to cover the hole in the seat mounts, fortunately I had some that worked. But these definitely cured a problem for me.

I had just bought a new toilet seat and the included plastic bolts were crap. The seat came loose after a week. I knew there were metal ones out there but I had never seen this design before. Install wasn't super difficult. I removed the seat completely, took the screw out of the rubber piece, and then used a little finesse to twist and push them through the hole. The "ball" should be under the hole and the flared out end should rest on top of it. Once I got the seat lined up and put the metal bolt/washer in, it was as simple as screwing them in place. Didn't even have to hold the rubber underneath the seat. Just make sure you don't over tighten it. The seat is VERY secure. Wish I had known about these earlier.

so much for "standard" sizing. does not fit in hole for toilet hinge screw. so i put it in upside down thinking that might help. it fit, but upon putting in screw/washer, toilet seat is loose & all over the place. the old cheap plastic screw must go back in. sigh. thought we'd finally found a solution to errant toilet seat.

Not universal. Different sizes have the same size rubber housing, so just wasted $20 UPDATE: if you’re having trouble with the fit, first try unscrewing the screw out of the rubber completely. Push the rubber into the toilet holes, and assemble the seat on top. The top rubber will be easier to squeeze through without the screw there. Once everything is together, then screw in the screws. Docking a couple stars for no instructions, and for confusing options. Ended up using the thicker screws with the larger washers from the thinner set.

I had about given up finding something to secure a new toilet seat to my useless Toto toilet ( never buy one ). You can not get to the underside of the hole that the seat fastens to. The engineer that designed this probably died of frustration trying to use his toilet. I saw these on Amazon and a last ditch effort tried them. You have to really crank the screw tight but once they tighten it the seat will not move a bit. You have to carefully push the ball inside the rubber sleeve firmly but if you bought the right model it will go in the hole and hold the seat.

De maravilla este producto, he probado otros y no he tenido buenos resultados, pero este me fue fenomenal, lo recomiendo 100%

I have one of those new style toilets where the bottom of the screws are not exposed but I wanted to put a bidet top on. This saved the project. Glad I found them.

Perfect solution
