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

This short film explains how to use screws, nuts and bolts to fix components together.

Screws, nuts and bolts are very useful for fixing components together.

This film will take you thought the various options there are, and how you can use them to the best effect.

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).
