Different Hook End Types of Helical Extension Springs

Various hook end types are used to attach extension springs to the force source. The most common types include machine loop and crossover loop. Extension springs do not have a solid stop like compression springs, resulting in lower stress levels. Drawbar springs have a solid stop and are a unique type of compression spring with special hooks.
