ICSE Class 9 Answered

Could you explain the pitch of the screw gauge in simple words please, it is urgent? Thank you

  • The pitch of the screw is the distance moved by the screw along its axis in one complete rotation of its head.
  • There are graduations along the circumference of the head of the screw.
  • There are 50–100 graduations. This is called the circular scale or head scale.
  • The pitch of the screw is 1 mm. If there are 100 divisions on the circular scale, then the least count of the screw is 1/100 = 0.01 mm = 0.001 cm.
  • The least count of a screw is the distance moved by it in rotating the circular scale by one division.
