innengewinde

Innengewinde, also known as internal threads, refer to helical grooves cut or formed inside cylindrical or conical surfaces, designed to mate with external threads (exterior threads) on bolts, screws, or studs. These threads are commonly found in components such as nuts, pipes, and threaded holes in mechanical assemblies, enabling secure and adjustable connections.

The primary purpose of an innengewinde is to create a tight, rotational lock between two parts, allowing for force transmission, positioning, or disassembly. Thread standards, such as those defined by ISO, ANSI, or metric systems, dictate the dimensions, pitch, and profile of innengewinde to ensure compatibility and reliability. Common thread profiles include triangular (60°), square, and buttress shapes, each suited for specific applications.

Manufacturing innengewinde involves processes like tapping, threading, or rolling. Tapping is a machining operation where a tapered or plug tap is used to cut internal threads into pre-drilled holes. Thread rolling, on the other hand, deforms the material to form threads without removing excess material, often resulting in stronger threads. For mass production, thread rolling is preferred due to its efficiency and durability.

Innengewinde are critical in industries such as automotive, construction, and manufacturing, where precision and strength are essential. Proper selection of thread size, material, and manufacturing method ensures optimal performance and longevity of threaded connections. Corrosion resistance, thread lubrication, and proper torque application are also important considerations to prevent failure and ensure smooth operation.
