Real basin waste nuts are octagonal. Is the image simply generic or is this the wrong product for octogon nuts?** A: I can confirm that it is a hexagonal box spanner. I think some plastic backnuts are octagonal - although not all - and also some are 47mm and are too big for this spanner. If you buy a brass backnut it should fit and they are stronger than the plastic versions. **Q: What is the measurement across flats at both ends please. I have a brass back-nut that is 38mm across flats and need a box spanner to fit. Is this it?** A: No **Q: The brass backnut on my basin waste is 45mm acroos the flats and I want to know if this basin wrench/box spanner is the correct size. Please advise** A: I have used this product a lot and it has fitted all the wastes I have tried it on. Great buy 😊 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very efficient tool. *by A***R on 10 April 2026* If you have awkward access under your basin and the metal back nut is well corroded/stuck then this tool is great!

Good product *by G***E on 5 February 2026* Bought this to use it on a 50mm waste basin sprung nut. It works. The only downside is that the plastic nut is bigger. You have to file the nut a little bit. 5 extra minutes of work. I used a small file. After that to tighten it was easy.
