IssueIssue DescriptionSolutionHow do I get more Help?
Wire Diameter

0.008" to 0.078" Music Wire (MW) and Stainless Steel 302 (SST 302) in all sizes. For sizes 0.079" to 1.250" please refer to the wire diameter table Click here!

Please make sure your wire diameter corresponds with one on the wire size list If you need a quote out of another wire diameter please email us at quote@acxesspring.com
Index too small

Minimum index is 4.0 on wire diameters from 0.008" to 0.115" and 3.0 on wire diameters 0.118" and above

Index = Mean Dia. ÷ Wire Dia.

If your index is too small you will need to decrease the wire diameter or increase the outer diameter If you need help with a spring index issue, please email us at quote@acxesspring.com
Index too large

Maximum index is 25.0 on all wire diameters.

Index = Mean Dia. ÷ Wire Dia.

If your spring index is too large, you will need to increase the outer diameter or decrease the wire diameter If you need help with a spring index issue, please email us at quote@acxesspring.com
Outer Diameter is outside the quotable ranges Outer diameter must be larger than 0.050" Make sure you increase the OD to 0.050" or greater. If you need a quote on a spring with an OD outside the quotable ranges, please email us at quote@acxesspring.com
Free Length is outside the quotable ranges Free Length must be larger than 0.130" Make sure you increase the FL to 0.130" or greater.

If you need a quote on a spring with a FL outside the quotable ranges, please email us at quote@acxesspring.com

Total Coils are outside the quotable ranges Minimum 1 active coil (3 total coils). Maximum 500 active coils. Make sure your spring has between 1 and 500 active coils. If you need a quote on a spring with active coils outside the quotable ranges, please email us at quote@acxesspring.com
Solid Height is greater than Free Length

Solid height must be less than free length.

Solid Height = Wire Dia. x Total Coils + Wire Dia.

Make the wire diameter smaller, the free length longer, or reduce the number of coils. If you need help solving a solid height conflict, please email us at quote@acxesspring.com
Pitch is too high Pitch must be less than 10 times the wire diameter.  Add coils, increase the wire diameter, or reduce the free length. If you need help solving a pitch conflict, please email us at quote@acxesspring.com
