0.5625-18UNJF is the inch notation of 9/16-18UNJF.
Even with 9/16-18UNF taps, the shape of the internal thread is the same, so if the accuracy is correct, machining is possible.
(The pilot hole diameter of the UNJF must be varied from the size of the UNF.) ）
However, you need to pay attention to the thread accuracy.

The spark plug standard is M14S × 1.25. See JISB8031.
Since OH4 falls into the category of OH4 accuracy, A-SFT's M14×1.25 (STD+1) (= OH4) corresponds to it.
Ｍ１０Ｓ×１→ＯＨ３
Ｍ１２Ｓ×１．２５→ＯＨ４
Ｍ１４Ｓ×１．２５→ＯＨ４
* In 1995, the standards for spark plugs for internal combustion engines were revised.
