Frequently Asked Questions
What is an APPROVED VENDOR extension tap used for?
An APPROVED VENDOR extension tap is used for threading blind holes or hard-to-reach areas in metalworking. The extended shank allows access to recessed surfaces where standard taps cannot reach. It is commonly applied in automotive, aerospace, and general manufacturing for creating internal threads in steel, aluminum, and other materials.
What are the specifications of the APPROVED VENDOR extension tap MPN 21022?
The APPROVED VENDOR extension tap MPN 21022 has a M8x1.25 metric thread, D5 / 6H tolerance, 2 flutes, plug chamfer, and is made of high-speed steel. It is a spiral-point design for efficient chip evacuation. These specs ensure precise threading in blind holes and are suitable for general industrial tapping applications.

How to select the right extension tap for a job?
To select the right extension tap, match the thread size (e.g., M8x1.25) and tolerance class (e.g., 6H) to your hole specifications. Choose a plug chamfer for blind holes or taper for through holes. Consider material hardness—high-speed steel works for general metals. Ensure the shank length reaches the threading depth without interference.
