What is limit plug gauge

The gauge has two ends with standard maximum and minimum tolerable size of the hole.


Instructions for use

  • GOGO side ( can pass through the whole holes smoothly)
    The GO side is used to check if the diameter of the hole which is bigger than the
    maximum entity size【minimum tolerable size of the hole】, the gauge can go
    through the hole completely.
  • NO-GO side (can not pass through the hole)
    The NO-GO side is used to check if the diameter of the hole is smaller than the minimum
    entity size【maximum tolerable size of the hole】, the gauge can notgo into the hole.
 
What is entity size
The volume of hole is the minimum when the 
hole is finished with minimum tolerable size. 
Therefore, the other volume except the hole 
(this is entity size, the right drawing with slanted 
portion) is the maximum, that is the maximum 
entity size. The opposite meaning of above 
mention is the minimum entity size.

  • Grade / same with the tolerance of the hole, plug gauge also has H6~H10.
    The smaller the number the more precise it is.
  • Hardness / HV600~780
*Make sure there is no error on the grade.
 
Vickers hardness (HV):Press the square pyramid shape diamond indenter against the
surface of the material to do indentation hardness test.

Precautions before use

  • Make sure the tip of plug gauge
    without any burrs.
  • Burrs may hurt the hole.

Precaution after use

  • Remove all dust and fingerprints
    then apply anti-rust oil.
  • Keep it at a place with small changes
    in humidity and temperature.
