The limit gauge for insert screws is the limit gauge for inserting inserts (helisate).
HL-LG is a unique symbol for OSG. The limit gauge is a set of GO and one on the stop side.

The difference from a normal thread gauge is that the plug gauge for insert screws is indicated with an H in the circle after the size .

A external thread -shaped gauge that inspects the effective diameter of a internal thread .
If it stops within the regulations, it will pass in that the effective diameter is not too large, and the thread accuracy is guaranteed by inspecting and passing it as a set with the thread screw plug gauge.

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

A internal thread -shaped gauge that inspects the effective diameter of a external thread .
If it stops within the regulations, it will pass in that the effective diameter is not too small, and the thread accuracy is guaranteed by inspecting and passing the set with the thread thread ring gauge.
If there is a distinction between machin

The figure below shows the positional relationship between the tolerances of each effective diameter in thread accuracy and thread gauge accuracy.
