OK, anoraks, what nut does the 9/16W box spanner in the P type tool kit fit? There isn't a comparable one in the J tool kit so I'm curious what big nut on the P type it removes.
Hi Simom. This box spanner was supplied in the tool kit for undoing the large castellated nut that holds the drop arm on to the steering box shaft. They were single ended, marked with the size, and are also used for undoing 'hen's teeth'!
