## Description

308L Waste Nut Box Spanner 46 x 50mm

Review: Good tap wrench - Good value for money. Works well. Packaged well delivered well. Well made. I am a skilled electrical mechanical engineer by profession and was an on screen expert for BBC Watchdog and Rogue Traders for some years and subsequently sworn to honesty. I tend to research a product drilling down into the quality and value of the item before I buy. I am not paid for my reviews and have no personal gain from them. I have no difficulty recommending this item. What's not to like. Go buy!
Review: The spanner to tighten your nuts - I had battled with a leaking sink having installed a new plughole fitting. The pictures show the old one. This spanner, which I wish I had bought months ago, fitted the new (and old) plastic holding nut perfectly. I was able to hand-tighten the nut at last. Works well and is very sturdy. So much easier than dismantling a bathroom!

## Questions & Answers

**Q: What size basin waste backnut does this fit please? will this fit a standard bsp "one and a quarter inch" waste hex backnut (brass or plastic)?**
A: This wrench fits one end 45mm the other end 50mm waste a wonderful tool only let down by not supplying a bar to turn it but this be easily done with a piece of rod or screwdriver

**Q: The image is a hexagonal box spanner. 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 😊

### ⭐⭐⭐⭐⭐ The spanner to tighten your nuts

I had battled with a leaking sink having installed a new plughole fitting. The pictures show the old one. This spanner, which I wish I had bought months ago, fitted the new (and old) plastic holding nut perfectly. I was able to hand-tighten the nut at last. Works well and is very sturdy.

### ⭐⭐⭐⭐ It works. 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. Used only my hands
