Many improvements to Steel Products

The Technofast team designed a special nut to achieve required size. The ease of fitting and the tensioning has reduced the overall time by two thirds and manning from 6 to 3. The implementation of this setup has allowed us to reach the timelines required for shutdowns on these Machines
