That would work with the bottom one but with the top one I could only get the spanner to sit upright rather than out to one side.

When I did mine I simply used my 18" breaker bar (from Halfrauds) and the 12pt socket.  There is just about enough room to get in there and sort it.

Unfortunately the breaker bar I have doesn't bend beyond 90 degrees.

Can someone explain the difference between a 12pt socket and a 'normal' socket. My trusty old set is probably 'normal' but the 19mm one seemed to fit quite tightly.

12 point on the left



Sometimes called bi-hex and single-hex.

A 12 point socket will work with a standard six sided bolt or nut. However a 12 point bolt or nut will be damaged using a standard socket as the points are small and need the support of the correct socket. Basically, the points get rounded off very easily with a standard socket.
