The 66421SCS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.013" diameter 316 stainless steel, the 66421S spring design exhibits reliable strength across its 22 active coils, withstanding repeated compression cycles with a maximum load of 0.448 lbf without succumbing to fatigue.

We manufacture the 66421S design to provide a compression spring that is 1.75" long at rest and provides a consistent rate of 0.61 lbs/in along its recommended maximum of 0.734" deflection. For best results, your application should fully accommodate the inner (0.13") and outer (0.156") diameters of this spring and be designed for its closed end configuration.
