Gewindeprofilformen

Gewindeprofilformen, also known as thread profiles, are the cross-sectional shapes of screw threads. They are crucial in determining the fit and function of threaded fasteners. The most common thread profiles include:

1. Trapezoidal (ISO metric): This profile is characterized by a flat top and a sloping flank. It is widely used in ISO metric threads and is known for its good load-bearing capacity and ease of manufacture.

2. Triangular (UNC): The triangular profile has a flat top and two sloping flanks. It is commonly used in Unified National Coarse (UNC) threads in the United States and is known for its high strength and resistance to stripping.

3. Acme: The Acme profile has a flat top and a 29-degree flank angle. It is used in Acme threads and is known for its self-locking properties, which prevent the threads from turning under load.

4. Square: The square profile has a flat top and two 90-degree flanks. It is used in square threads and is known for its simplicity and ease of manufacture.

5. Buttress: The buttress profile has a flat top and a 45-degree flank angle. It is used in buttress threads and is known for its high strength and resistance to stripping.

Each thread profile has its own advantages and disadvantages, and the choice of profile depends on the specific application and requirements.
