BOSS MJ / UNJF Aerospace Taps are specialized tapping tools developed for aerospace and high-precision thread machining.
Unlike conventional Metric or Unified threads, aerospace threads require tighter control of thread geometry, dimensions, root profile, tolerance and inspection requirements. Selecting the correct tap according to the engineering drawing is therefore critical.
BOSS offers MJ / UNJF Aerospace Threading as a dedicated product category. The MJ system is referenced to ISO 5855, while UNJF is referenced to ISO 3161 / ASME B1.15. Asp Boss
For the MJ system, MJ4H / 6H is referenced according to ISO 5855. For UNJF, UNJF-3B is referenced according to ISO 3161 and ASME B1.15. 同嶺企業有限公司
The range is intended for applications requiring high thread accuracy, including aerospace components, precision mechanical parts and specialized engineering applications.
For aerospace components, Tô Gia recommends selecting the tap according to the engineering drawing, thread standard, nominal size, pitch, tolerance class and thread inspection requirements, rather than selecting only by nominal diameter.

German BOSS Spiral Flute Taps feature optimized spiral flute and chamfer geometry for efficient chip evacuation, especially in blind holes. Multiple coatings such as TiN, VAP and TiCN are available depending on the model to improve tool life and reduce chip-related problems.
BOSS POT taps feature Straight Flute, Spiral Point and Form B 4–5 threads chamfer geometry, optimized for through-hole tapping. Forward chip evacuation helps reduce chip packing and improve tool life.
BOSS Roll Taps (Formex - Forming Taps) produce internal threads by material forming without generating chips. The forming process provides a smooth rolled thread surface, high thread strength and improved tap durability.
BOSS Nut Taps are specialized tapping tools for nut manufacturing, designed around nut characteristics and tapping machine requirements to deliver thread accuracy, tool life and stable production.
