The 1/2 inch UNF hand tap has a nominal diameter of 0.5 inches and a thread pitch of 20 threads per inch TPI, designed according to the Unified National Fine UNF standard. Its thread angle is 60 degrees, which enhances strength and joint quality. The tap is typically made from high-speed steel HSS with a hardness between 60 to 65 HRC, ensuring high resistance to wear and heat. The overall length usually ranges from 70 to 90 millimeters, and its square shank allows for easy installation in a tap wrench. Precise chip removal flutes reduce friction and improve threading quality.
This hand tap is widely used for creating precise internal threads in both soft and hard metals. The recommended pilot drill size is 10.5 millimeters to achieve optimal thread engagement. The suggested manual operating speed is between 10 to 15 revolutions per minute to prevent tool breakage. The 1/2 UNF tap is extensively used in aerospace, automotive, and industrial repair industries, providing excellent thread quality.
