Tapping and threading are both essential machining processes used to create screw threads in materials, allowing for secure fastening and mechanical connections. While they are often used interchangeably, they have distinct differences in terms of process, application and tools used. Understanding these differences helps manufacturers choose the right method for their specific needs.
What is Tapping?
Tapping is the process of cutting internal threads inside a pre-drilled hole using a tool called a tap. This process allows screws or bolts to be fastened securely within the material. Tapping can be done manually using a tap wrench or automatically with tapping machines, which ensure greater precision and efficiency in high-volume production.
Tapping is commonly used in metalworking, construction and manufacturing industries. It is essential for creating secure connections in materials like steel, aluminium and plastic, ensuring strong, durable threads that can withstand mechanical stress.

What is Threading?
Threading refers to the process of creating screw threads on both internal and external surfaces. Internal threads are made using taps, while external threads are cut using dies or thread-cutting tools. Unlike tapping, threading can be done through various methods, including thread milling, rolling, or turning, depending on the application.
Threading is widely used in manufacturing processes where precision and consistency are required. It is commonly applied in producing fasteners, pipes and industrial components that require threaded connections.
Key Differences Between Tapping and Threading
Process: Tapping is a subset of threading that specifically creates internal threads, while threading includes both internal and external thread formation. Tools Used: Tapping requires taps, whereas threading can be performed using dies, mills, or rolling tools. Application: Tapping is primarily used for fastening applications, whereas threading is used for both fastening and motion control in mechanical systems. Automation: Tapping is often performed using tapping machines for high efficiency, while threading can involve multiple machining techniques.
Both processes play vital roles in engineering and manufacturing, ensuring strong, precise, and reliable thread connections in various applications.
