Measurement Method of Compression Coil Springs
When you want to purchase the compression spring, you should measure the sizes below:
1. Outer Diameter of Compression Springs
2. Free Height of the Compression Springs
3. The Wire Diameter of the Wire Used for the Compression Springs.
Please use a vernier caliper instead of a tape measure when measuring the compression spring size.
Because the vernier caliper can be accurate to 0.01mm, which is more accurate, while the tape measure can only be accurate to 1mm, which is very error-prone, resulting in a large difference between the measurement result and the actual one.
Usage
