Corrosion-Resistant Die Springs
A quieter, more vibration-resistant alternative to traditional steel die springs, these polyurethane springs resist oxidation, oil, and abrasion in high-load, high-pressure applications.
Deflection is the distance the spring compresses, expressed as a percentage of its length.
As you squeeze a die spring, it gets harder to push. Spring rate is the amount of force required for every inch of compression. The higher the spring rate, the harder it is to compress the spring.

Die Spring Screw Caps
In addition to providing a backing for springs, these screw caps can also be used to control spring tension. Install them by drilling and tapping a hole through your die set.
