What to consider before buying

Consider the material (music wire, stainless steel, or chrome silicon) based on environment and load requirements. Check spring dimensions (outer diameter, free length, wire diameter) to ensure fit. For precision applications, look for tight tolerances; for harsh environments, stainless steel is recommended. Balance price with durability needs.
