2 Packs Toilet Seat Hinges Fixings, Quick Release Toilet Top Fix Blind Hole Fittings,Toilet Seat Hinge with Spare Expanding Rubber Screws Nuts Bolts for WC Toilet Blind Holes.

Great, worked as intended.

Just what I needed toilet seat decided to losen and ultimately fall off when I first installed it I remember having problems with the side slip when you sit on it had to upgrade the security with an long screw accompanied with nut and washer.during the time it's been fixed on I had a stroke so when it came off I thought oh this is going to be fun with only 1 working hand to secure it I Needn't have worried literally 10 minutes and toilet seat is back on and extremely secure was so much easier than first time round wil update at a later day to see if it's still holding or if we have gone back to the side slip the only down side is the metal cap that covers the scre is blue I thought it was maybe a protective cover but no I can't get it off so I'm going with quirky

Excellent product. Very easy to fit. Works well.

The installation was simple enough and they work good. At first, I thought the screws weren't tightening properly but it just ended up taking longer than expected to get a tight fit. The only reason I didn't give five stars was because even when tightened to the max, they still have the tiniest bit of a wiggle/give to them. It's not even that noticeable when actually using the toilet, I just wanted to make a note of it

Bought to replace the screw fixing as it had broken off. That worked fine but as the other reviews say, these are not universal. The “spikes” did not fit my toilet seat, they were too big but I just used the old ones as they were still fine.
