Frequently Asked Questions
Q: What is the difference between pitch and the space between the coils?
A: The pitch is the distance from center to center of the wire in adjacent active coils. The space between the coils, is the distance from end to end of the wire in adjacent active coils. Follow the link below and look for the compressions spring in the right hand corner to see the difference.
Q: What the best tool for measuring the dimensions of a spring?
A: The most accurate way is with a pair of calipers, especially if it’s a smaller spring. The next best is a sliding rule.
Q: I am interested in learning more about springs. Where can I find this information?
A: Follow the link below to an in-depth discussion on the properties of a compression springs.
Compression springs info
Extension springs info
Torsion springs info
Wire forms info
Q: What does “load” stand for?
A: The load specifies the maximum safe weight in pounds to use on the spring. Using more load will cause the spring to be overstressed.
Q: What if my spring does not match one of the stock items?
A: Give us a call or email your specs to email@example.com
Q: What’s the difference between hard drawn and music wire?
A: Both are high carbon spring wire. However, hard drawn is generally used for low stress applications where as music wire is better for higher stressed projects. Hard drawn is also cheaper than music wire. Check our glossary out for more info.
Q: How can I tell stainless steel and carbon steel apart?
A: The best way is to use the spark test. With a hand rotary tool, gentle touch the spring to the sanding plate. If the spring sparks, it is carbon steel. To learn more follow the link below to our blog post about materials.
Q: Do you also carry stainless steel stock items?
A: Yes, we have a variety of stainless steel springs. However, we can also make any stock item in stainless steel, please call or email a request. The rate of the stainless steel spring will be about 15% less than the equivalent carbon steel stock item.
Q: How do you cut one of the cut-to-length springs?
A: For smaller wire diameters, a hand help nipper will work. However, large wire diameters should be cut with an abrasive cut off wheel.
