    Cut-to-Length Compression Springs

    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.
    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).

    Extension Springs

    The farther you stretch these springs, the harder they pull to bring the two ends back together. They're commonly used to tension cable, return an air cylinder to its starting point, or hold a door closed.
    Loop End—The most secure attachment method. With fully closed loops, there's no risk of slipping off.
    Double-Loop End—Ends are strengthened by an extra loop, so these springs are less likely to break if overstretched.
    Hook End—Hook into closed holes, such as hanger bolt eyes. These springs work best when kept under tension, as they're more likely to slip off than loop-end springs when tension is released. Also known as machine hook ends.
    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.
    Highly Corrosion-Resistant 316 Stainless Steel—Our most corrosion-resistant stainless steel springs won't degrade when exposed to salt water and harsh chemicals. They're 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.
    Maximum Load—The amount of force required to fully extend the spring.

    Compression Springs

    Image of Product. Front orientation. Compression Springs.
    Squeeze these springs and they’ll push right back to their original length. When compressed, they apply steady pressure to keep components securely in place. Release the pressure and they snap back instantly, just like the tip of a ballpoint pen.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    High-Strength Chrome Silicon Steel—The chromium and silicon boost strength and fatigue resistance for high-stress uses, such as suspension systems and stamping presses. However, these springs are best suited for dry environments since moisture will cause them to rust.

    Die Springs

    Image of Product. Front orientation. Die Springs. Die Springs.
    Support loads in small-batch die press jobs. Made of tempered spring steel, these springs stay strong and resilient in dry environments. If you need a stronger metal that’s less likely to rust, consider Color-Coded Die Springs. The closed, ground ends of these springs create a flat surface that balances your load, even as it moves.
    Deflection @ Maximum Load—The percentage represents how much a spring compresses from its original length.
