## Customer Reviews

### ⭐⭐⭐⭐⭐ Silverline 719819 Monobloc Back Nut Tap Spanner 9/11 and 12/13mm
*by P***G on 4 September 2014*

Bought these after seeing other reviews for these box spanners. Very good price and were indispensablein removing my old Monobloc kitchen tap and fitting a replacement. These spanners made the job of removing thetap-securing nut from under the sink so easy. I used a small socket set with a ratchet to fit a socket on thebottom end of the box spanner and had the nut removed in a minute or two. fitting the new tap to the sink toptook the same amazingly short time and saved me having to remove the sink to get to the nut - best £2.75 I havespent in a long time.
