The M8 hex wrench is an extended glow plug wrench that can be used for normal or turbo glow plugs.
The M10 hex wrench is perfect for loosening/tightening a flywheel clutch nut.
The perpendicular axle allows loosening/tightening glow plugs and flywheel clutch nuts easily. It also comes with a 5 mm allen wrench for loosening/tightening the 5mm allen nuts.
