What is a ISO-H tap?

An ISO-H tap is a type of threaded tap used for creating internal threads in materials, specifically designed to meet the International Organization for Standardization (ISO) standards. The "H" designation indicates that it has a tolerance class, ensuring a specific fit for screws and bolts, typically used in precision engineering applications. ISO-H taps are commonly made from high-speed steel or carbide and are used in various materials, including metals and plastics, to produce strong, reliable threads.
