We have some special hybrid box spanners/sockets made.Designed to undo nuts with up to four inches of shaft or thread projecting.Various applications,hub nuts,axle shafts,gearbox and clutch assemblies.Various AF ,Whitworth and BSF sizes.You can see them here.
We can also supply model specific wheel braces,forget worrying about the strength of your 1/2 drive bar and tight wheel studs,some of these are made from two inch diameter solid steel!
AF tools... AF stands for Across Flats. .Spanners stamped with an imperial fraction mean that the spanner or socket is that size in inches across its parallel faces.So a spanner stamped 1/2 is a half inch across its parallel faces. These tools are designed to fit nuts and bolts mainly having UNF or UNC threads.These fixings are encountered on older cars,motorbikes and other machinery.Its difficult to give precise dates as the Americans and others used it for longer periods than others and some foreign makers have always used metric . Metric spanners can also be called AF,for example a 19mm metric open ended spanner is 19mm AF.
BA...stands for British Association a virtually obsolete standard using a mixture of decimal inch based sizes.Used on smaller fixings especially on electrical parts it is unusual in that the higher the BA number the smaller the fixing/spanner.0 BA is the largest and 10 the smallest size generally encountered although they are made right down to 23BA.
Whitworth  (British Standard Whitworth or B.S.W. ) ...named after the British engineer who invented it.An pre war standard for threads and spanner sizes.The fine version (more threads per inch) version of whitworth is called British Standard Fine (B.S.F) The size of a whitworth (or BSF) spanner refers to the thread not the size of the bolt head.Phased out by the 1960's officially obsolete after 1965 but some manufacturers carried on using it on some applications much later than this.If you are a classic car or motorcycle enthusiast you'll come across Whitworth and BSF sooner or later..(and the threaded hole in the bottom of your new camera is almost certainly tapped 1/4 whitworth) Whitworth thread is coarser than.BSF but the same spanners fit either.
