    Always be ready for the perfect fit. These springs are extra long to cut a custom length whenever you need it. Their open ends make cutting easier but prevent them from standing on their own. You’ll need to install them in a hole or over a shaft, or grind the ends flat.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Corrosion-Resistant 302 Stainless Steel—Won’t corrode from exposure to moisture and mild chemicals, including ammonia often found in cleaning solutions. These springs are easier to compress than steel, but can’t handle as high a load.
    Spring Rate—To determine the spring rate of a cut spring, first multiply the spring rate given by the spring's original length, then divide the result by the cut length (in inches).

    Keep these springs on hand so you can cut the right length whenever you need it. Bend their straight-cut ends into custom loops or hooks.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Corrosion-Resistant 302 Stainless Steel—Won’t corrode from exposure to moisture and mild chemicals, including ammonia often found in cleaning solutions. These springs are easier to extend than steel, but can’t handle as high a load.
    Minimum Load—The amount of force required to start extending the spring.
    Spring Rate—To determine the spring rate of a cut spring, first multiply the spring rate given by the spring's original length, then divide the result by the cut length (in inches).

    Keep these extra-long springs on hand, so you can cut the right length whenever you need it. Install these springs in your die press for small-batch jobs. Made of tempered spring steel, these springs stay strong and resilient in dry environments. Trim your spring, then grind the open ends flat to balance your load.
    Spring Rate—To determine the spring rate of a cut spring, first multiply the spring rate given by the spring's original length, then divide the result by the cut length (in inches).
