    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.
    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.
    Ultra-Corrosion-Resistant Cobalt Nickel—The best choice when you need both corrosion resistance and strength. These springs resist stress corrosion and pitting from salt water and harsh chemicals. Plus, they’re 10% stronger than 316 stainless steel.
