Description

  • Precision 1 3/8-20 UN Specifications: Contains one 1 3/8-20 UN machine plug tap and one matching 1 3/8-20 UN round die. Optimized for creating or repairing threads with a constant 20 Thread Per Inch pitch.
  • Industrial High Speed Steel: Manufactured from HSS (High Speed Steel) for superior hardness and wear resistance. Engineered to maintain cutting edge sharpness when working with carbon steel, alloy steel, aluminum, and cast iron.
  • Standard Right Hand Cutting: Both the tap and die feature a right-hand (RH) cutting direction. The plug tap includes a lead taper for easy starting, while the round die ensures a clean, accurate external thread profile.
  • Specialized UN Thread Application: Designed for heavy-duty mechanical engineering and maintenance where standard coarse or fine threads are not used. Suitable for large-diameter threading on shafts, pipes, and custom fittings.
  • Clear Size Marking: Each tool is laser-etched with the 1 3/8-20 UN size and Thread Per Inch details, allowing for quick identification and selection in professional workshop environments.
