Stop Marks Stop Marks Female screws processed by cut taps have stop marks. If it presents a problem, the use of OSG's thread mill series is recommended. Geometry Interrupted thread geometry The variable skip tooth geometry prevents galling by maintaining appropriate amount of cutting depth. Geometry comparison of A-TPT and A-S-TPT Taper pipe taps Rc(PT) and NPT employs two types of geometries from the conventional TPT and S-TPT. The length of threaded parts and gauge diameters of TPT and S-TPT are following JIS B 4446 Appendix. Hand Taps for Pipe Thread for Taper Thread (PT Series Taper Taps and PS Series Parallel Taps).
