50-75mm Screw Thread Micrometers for Accurate Thread Measurement in
Different Sizes and Pitches
Quick Detail:
1. Painted and fine cast frame.
2. Laser-etched scale for clear and easy reading.
3. Supplied with 60° or 55° V-shaped and knife-edged
interchangeable anvils are optional.
4. Ratchet stops.
5. Supplied in fitted case.
Description:
Our KM-2291 series thread micrometers, also known as pitch
micrometers or plug micrometers, it can be applied to thread
measurement of different sizes and pitches, the reading indicates
the thread pitch diameter.
Screw thread micrometers supply with interchangeable 60° V-shaped
and knife-edged anvils that are shaped to match
the thread profile, each measuring range is equipped with several
pairs of anvils. By changing different anvil combinations,
different range of thread parameters can be measured.
We supply a full measuring ranges from 0-25mm to 175-200mm to meet
different measurement requirement.

Precautions:
Screw thread micrometer is a precision measuring tool. It should be
used with care and gentleness, and do not let it
be hit or collided. The threads in the micrometer are very precise,
so please pay attention when using them:
1. Neither the rotary knob nor the force measuring unit should be
rotated with excessive force.
2. When turning the knob to bring the micrometer screw closer to
the object to be measured, be sure to rotate the force
measuring unit. Do not turn the knob to make the screw press
against the workpiece to be measured.
3.When the micrometer screw and anvil have jammed the workpiece to
be measured or tightened the locking device,
never turn the knob forcibly.
4. When using a micrometer to measure the same length, the
measurement should generally be repeated L times,
and the average value should be taken as the measurement result.
5. After using the micrometer, wipe it clean, leave a little gap
between the anvil and the screw, and put it in the box.
If it is not used for a long time, apply engine oil and place it in
a dry place. Be careful not to expose it to corrosive gases.
Applications:
Screw thread micrometers have the advantages of high precision and
wide measurement range, and are widely used
in mechanical processing, instrument manufacturing, automobile
manufacturing and other fields.
