Adjustable Spanner

An Adjustable Spanner or AJ is a spanner whose jaw has an adjustable width. It is a useful tool to have for get ins, with uses from tightening wing nuts on a fixture (especially useful the fixture only has a normal bolt) to assembling steel deck. An AJ with a length between 150mm to 200mm is ideal, as it can fit in your pocket, but still give enough torque to be useful.
