Exactly the same as any other nut. Spanner is just British terminology for wrench.
How to calculate spanner size regarding bolts and nuts
you use a spanner to open a rusted nut bolt because you need a strong tool to open a rusted nut bolt.
Because a spanner provides extra leverage - and is much tougher than our fingers !
because spanner has a longer moment arm and torque depends upon moment arm greater the moment greater will be the torque produced so it is easy to unscrew a tight nut using longer spanner
The longer spanner gives you a greater "mechanical advantage". If you search for "The six simple machines" there are loads of excellent explanations... you can think of the spanner as a either lever with the pivot point (or fulcrum) at one end, or as a single spoke from a wheel (where the nut is the middle of the wheel). Work is a force acting over a distance. Work (Joules) = Force (Newtons) x Distance (metres). Your muscles have a fixed maximum output of work... by using a longer spanner you are making the distance longer, so the amount of force needed to get the work done at the end you pull on gets smaller.
The mechanic would get more leverage. The rotational force applied to the nut is greater the longer the spanner, assuming the mechanic applies the same amount of force.
Is it heavy duty model with axle bolts? If so, Remove axle bolts Slide axle out of differential housing use spanner wrench to loosen spanner nut (or hammer and chisel) Remove spanner nut and seal Drum should slide off
open the boot, there is a very small flap near the boot lock, under this is a bolt that can be turned using one end of wheel nut spanner, when you have released the nut a fair bit you will be able to lift the wheel carriage under the car and move the hook out of the way, allowing the carriage to lower to the ground

That would be the nut that holds the steering wheel to the steering shaft.
In the 1630s, it derived from the German spanner,a tool for winding the spring of a wheel-lock firearm.The word meaning wrench is from 1790.Spanner in the works was first recorded in 1934.
