What is the German translation for "fastener"?

The term "fastener" in English generally refers to a device that mechanically joins or affixes two or more objects together. In German, the correct translation for "fastener" is "Befestigung." This word encompasses a variety of fastening devices such as screws, bolts, and other types of connectors, signifying its broad application in both construction and manufacturing contexts.

The other choices represent different but related concepts. "Verbindung" translates to "connection" or "link" and is more general, referring to the act of connecting rather than the specific fastening action. "Schraube" means "screw," which is a specific type of fastener, and not a translation of the word itself. Similarly, "Halterung" translates to "bracket" or "holder," referring more to the device that supports or secures an object rather than the overarching category of fasteners. Thus, "Befestigung" is the most accurate and encompassing term for "fastener" in German.
