This is a tap that can be screwed accurately and easily with trapezoidal screws, and is usually finished with a single raised tap after rough threading, or a pair of increased diameter taps may be used.
This is a special product.
Some of the drawing instructions may be multi-threaded threads, such as two-threaded screws or three-threaded screws.
It is a target cross-sectional screw with a large proportion of the top of the mountain and the bottom of the valley.
Currently, OSG supports trapezoidal screw taps and gauges as special products.

Types of screws PS and PF Is it possible to share thread machining tools and gauges?
Both are parallel screws for pipes, but the tolerance settings are different.
Gauges cannot be shared with machining tools.
BA thread refers to the type of thread called BA in the British Standard BS, and the thread angle is 47.5 degrees.
For example, if size is "2BA", then 2 represents the size number.
The size of the pitch is determined by the size number, and in the case of the
PT Screw Taper Angle What is the slope angle on one side?
It is tapered by 1/16 and becomes 3°34'47".
The slope angle on one side is 0.5/16 taper, 1°47'23" per angle.

List of tolerances for metric screws (JIS2 grade)
The conventional JIS standard for metric screws has been erased, so it cannot be confirmed from JIS.
In the table below, you can refer to some of the allowable dimensions and tolerances of the conventional JIS2 class, which are still commonly used today.
(ANSI) ASME B1.13M
(DIN) ISO965
