This is a internal thread -shaped gauge that inspects the total effective diameter of external thread .
If it passes through, it will pass in that the effective diameter is not too large, and the screw accuracy is guaranteed by inspecting and passing it as a set with the stop screw ring gauge.
In addition to the effective diameter, the

answer
Straight screws generally refer to parallel threads.

answer
The thread angle of W ( whitworth screw ) is 55°, and the thread angle of U (Unified) is 60°, so it is not recommended to fit them together.

M8×1.25 For 2nd grade,

The outer diameter of the GO gauge (GP) is +6~+18 micrometers compared to 8.

The outer diameter of the Tap varies slightly depending on the accuracy, but it is set at +60 micrometers or more, so it does not interfere.

answer

There is a difference in the second-class accuracy of the external thread with the reference effective diameter.

Class 1 threads start with a reference effective diameter.

If the workpiece enters during this time, this will be the result.

* The criteria for pass/fail judgment are different between the conventional JIS and the current JIS (ISO).

●Pass/fail judgment based on the current JIS (ISO)

PP GO (street): pull out through without difficulty (penetration)

PP NOT GO: Passes if neither side has more than one turn of the screw

●Conventional JIS pass/fail judgment
