Tight-Space Compression Springs
 |
Fit into the tightest spots with full compression. These conical springs nest their coils inside each other as they compress, shrinking to about two wire widths. You'll often find them in battery holders and push-button switches.
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.

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.
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.
