Design and Technology (D&T) KS3: Screwing components together

This video explains some of the most common options for fixing components together.

Teacher Notes

Points for discussion

  • When might you use nuts and bolts in stead of, for example, rivets or pop rivets?
  • How might you create the thread for a bolt when fixing together two components, when nuts are not an option?
  • Following on from this, how would you use taps and dies to create threaded components or threaded holes for assembling components?
  • What are the differences between the different types of permanent and non-permanent fixings?
  • Students could have a general discussion about standardisation, standard parts and the huge variety of nuts, bolts, bottle lids, locks, keys etc.

Suggested activities

  • Experiment with a range of materials and fixings and try various combinations to find out what might work best in a particular project.
  • Or, introduce techniques as necessary during FPT projects.
  • Play a version of Snap or Odd One Out using the various types of fixings (nuts, bolts, rivets, screws, machine screws, studding, etc).
