Review: Does the job perfectly. - Perfect, very easy to fit, no slip at all, great value, arrived within days of ordering, does the job.
Review: Simple, effective and cheap - In my rented home I have an expensive soft close toilet seat which was fine for almost 2 years then it started shifting no matter what I did. Took it off completely, cleaned every part thoroughly, reinstalled, was perfect... for a week, then started moving sideways again. Contacted the supplier who suggested buying a new one. At almost £100, em nooo. So I asked an AI tool what I could do and it suggested this product, which I had never heard of in my 66 years. Now installed, a wee bit fiddly but entirely doable, it has turned a nervous wait for a slide sideways into a laugh of "you can't get me now!" So simple but seems to be really effective as it takes up the wobble room on the hole in the toilet where the bolt goes through. Dont waste money on a new seat if this product can work for me, it can probably keep you sitting where the action happens !!

## Questions & Answers

**Q: Does this product come with instructions?**
A: I can't remember but they're very easy to fit. Take the long bolt out and slot it through the rubber, with a washer on the wide part of the rubber. Push the narrow end of the rubber into the hole on the underside of the toilet, then tighten the bolt and the rubber jams itself tightly into the bolt hole. Get the bolt good and tight but not so much as to crack the porcelain. There you go. Hope that helps. Good product by the way. A pack of 4 does for 2 toilets, in case you were wondering.

**Q: Does anyone know size of wing nut that i need to purchase and if possible the link**
A: Not sure that you need one. I just kept my existing toilet seat fixtures and was able to push / twist the FixIt washers up the existing screw fittings (the ones which come down through the holes on the back of the toilet)  and tighten using the existing wing nuts. They were a tight fit on the screws, but the rubber gives a bit and it was not that difficult (and I have arthritic hands).

**Q: Hello,can they be screwed on with the original plastic nuts ? thank you.,I saw somewhere it said only use metal .**
A: The nuts on my toilet are plastic, so yes. My toilet seat is tightened from underneath. These rubber washers have worked brilliantly so far and have totally resolved the problem of a slippery sliding seat.

**Q: How wide are the screw heads?**
A: Not 100% certain of your question. 
If you mean the overall diameter of the screw heads it is 11mm.
The screws have an overall length of 48mm including the screw head.

### ⭐⭐⭐⭐ Good but one fixing missing
*by W***Y on 30 January 2025*

Would have been five stars as they work very well. Great to be able to fix the seat without grovelling underneath. Very easy to fit. Only four stars as there were only three fixings in the pack instead of four. Only needed two for this job but a single remaining fitting is not of any use as all seats will require two.
