application of force. When tightening or undoing a hexagon socket
bolt, force should be applied to the nut wherever possible to avoid
damaging the bolt.
Tightening and undoing
Turn the nut using a socket spanner (only use an open-end
spanner if there is insucient space), using the Allen key simply to
stop the bolt turning.
