- Ratchet:It advances the screw by turning it until the object is gently held between the stud and spindle of screw.
- Sleeve:It marks the main scale and base line.
- Thimble:It marks the circular scale.
- Main scale:It helps to read the length correct up to 1 mm.
- Circular scale:It helps to read length correct up to 0.01 mm.
