Whitworth ...takes its name from the British engineer who invented it.An early standard for threads and spanner sizes.The size of a whitworth (or BSF) spanner refers to the thread not the size of the bolt head.Phased out in the 60's officially no longer used 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 you new camera is almost certainly tapped 1/4 whitworth) Whitworth thread is coarser than.BSF but the same spanners fit either.AF means across flats and indicates the size in inches of spanner to be used as do metric spanners.British Association or BA is a older British standard often found on dynamos,starters and electrical fittings on old British cars and motorcycles ....
Coarse threads (whitworth,unc etc) are more likely to be used on the thread in a casting,most nut/bolt assemblies will use a fine thread.Fine threads (BSF,unf etc) have a greater resistance to being shaken loose by vibration.Brass or similar soft metal nuts and bolts are normally coarse threaded for strength.
