The 3409CS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.108" diameter spring steel, the 3409 spring design exhibits reliable strength across its 5 active coils, withstanding repeated compression cycles with a maximum load of 32 lbf without succumbing to fatigue.

We manufacture the 3409 design to provide a compression spring that is 1.63" long at rest and provides a consistent rate of 39 lbs/in along its recommended maximum of 0.83" deflection. For best results, your application should fully accommodate the inner (1.08") and outer (1.296") diameters of this spring and be designed for its closed & ground end configuration.
