Die Springs are heavy duty metal compression springs manufactured using rectangle wire. The ISO 10243 standard defines the following parameters for rectangular section wire compression springs:
Dh: housing diameter, also known as external diameter;
Do: lead pin diameter, also known as internal diameter;
Lo: length of the spring in the resting position, also known as the free length;
R: load, expressed in Newton, necessary to deflect a 1mm spring (1 Newton = 0.102 kg).
