    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.

    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.
    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.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.

    Thread these ball socket end fittings onto gas springs. They rotate in any direction on a ball stud to compensate for misalignment. Ball socket end fittings require a ball stud or ball stud mounting bracket (sold separately) to mount gas springs; they have a safety clip for secure attachment.
    Select end fittings with a thread size that matches the rod and end thread sizes of your gas spring. The fittings will increase your gas spring's extended and compressed lengths, so add the Length 1 value for each fitting you attach.

    Snap-On Ball Socket Gas Spring End Fittings

    Image of Attribute. Front orientation. Gas Spring End Fittings. Snap-On Ball Socket Gas Spring End Fittings , Zinc-Plated Steel.

    Zinc-Plated Steel

    These end fittings snap right on a ball stud—an integral retaining clip grips the ball stud for secure attachment until you apply enough force to pop it off. Thread these ball socket end fittings onto gas springs. They rotate in any direction on a ball stud to compensate for misalignment. End fittings require a ball stud or ball stud mounting bracket (sold separately) to mount gas springs.
    Select end fittings with a thread size that matches the rod and end thread sizes of your gas spring. The fittings will increase your gas spring's extended and compressed lengths, so add the Length 1 value for each fitting you attach.
    Zinc-Plated Steel—Zinc-plated steel fittings are stronger than glass-filled nylon fittings—it takes more force to accidentally dislodge them. They’re heavier, though, and more likely to corrode over time as the plating wears down.
