Gewindeserie

Gewindeserie refers to a standardized series of thread sizes for screws and nuts. These series are established to simplify manufacturing, inventory, and interchangeability of fasteners. Different Gewindeserien exist for various applications and regions, each defining a specific set of nominal diameters and associated thread pitches.

Commonly encountered Gewindeserien include metric threads (e.g., M-series), unified threads (e.g., UNC, UNF), and pipe threads (e.g., NPT, BSP). The metric series, governed by ISO standards, uses millimeters for diameter and pitch. Unified threads, prevalent in North America, employ inches for diameter and specify the number of threads per inch. Pipe threads are designed for sealing in plumbing applications and have specific taper and sealing characteristics.

The purpose of a Gewindeserie is to ensure that a screw of a particular size and thread type will mate correctly with a nut of the same designation. This standardization prevents the need for custom-made fasteners for every application and allows for mass production, which in turn reduces costs. When selecting fasteners, it is crucial to identify the correct Gewindeserie to guarantee proper fit and function. Compatibility between different Gewindeserien is generally not possible without adapters or specialized tooling.
