Compression Spring Design Basics: Space, Travel and Two Load Points
A compression spring cannot be selected by envelope dimensions alone. Working heights, loads, travel and solid-height margin belong in one specification.

Choosing Extension Spring Hooks: Why Failures Often Start at the Ends
Hook form, transition radius, load direction and initial tension determine extension spring reliability and assembly behavior.
