Precision springs are specialty springs that are useful in industrial machines and equipment. Industrial springs manufacturers use hard drawn steel, music wire, spring steel and stainless steel to manufacture precision springs.

Some equipment and components that use precision springs are valves, clutches, compressors and measuring instruments. Some industries that use precision springs extensively are medical, aerospace, automotive, military and defense, computer, electronics and agriculture.

Some important parameters you must consider before buying precision springs are:

1. Dimensions: inner diameter, outer diameter, wire diameter and spring length
2. Material of the precision springs
3. Capability of compression, torsion and extension
4. Compatibility with other components
5. Expected useful life of the precision springs
