 |
Box spanners come in a wide variety of sizes, but for removing tap backnuts you’ll only really need a box spanner that can be used on 1/2 inch and 3/4 inch fittings. | |||
32mm box spanner |
||||
 |
The 32mm box spanner is a hexagonally-shaped metal tube which has an internal diameter of 32mm for fitting over nuts.
The tight-fitting socket allows the user to tighten or loosen 3/4 inch nuts and fittings. |
|||
27mm box spanner |
||||
 |
The opposite end of the box spanner consists of a smaller 27mm hexagonal metal tube with an internal diameter of 27mm for tightening or loosening 1/2 inch nuts and fittings. | |||
Tommy-bar handle |
||||
 |
The Tommy-bar (often called a “T-bar”) handle is a short metal rod that can be inserted into either of the holes in the body of the box spanner.
The handle is then used to apply leverage and rotational force to the box spanner, thus turning your required nut or fitting. |

Holes in a box spanner tap wrench |
||||
 |
The body of the basin box spanner has two sets of holes through which you can insert the T-bar handle.
The T-bar handle can be positioned at the top or bottom depending on which end of the spanner you are using or the level of access you have available. |
