Spanner is a hand tool which is used to turn objects usually
bolts and nuts. It gives mechanical grip and advantage in applying torque in
rotating objects. In some places spanners are also referred as wrenches.
Spanners are available in different sizes but popular are those spanners which
are adjustable. These adjustable spanners give the flexibility of usage over
the range of adjustment and are very useful where the sizes of bolts and nuts
do not vary much in size.
