Flat Wire Helper Springs

Premium 70-Series (Various IDs)

These 70-Series flat wire springs utilize a rectangular wire cross-section to achieve a lower solid block height compared to standard round wire springs. This design maximises usable stroke and is ideal for tender/helper applications where space is at a premium. Please check the Di column carefully as this series contains mixed Inner Diameters.
