32mm Springs | McMaster-Carr

With the Raymond color code, you'll always grab the die spring with the right load rating. The chrome-silicon steel is stronger than spring steel and handles repeated stress for longer periods of time. Rely on these springs for high-volume jobs, such as stamping and injection molding. A powder coating prevents rust in wet environments. The closed, ground ends create a flat surface that balances your load, even as it moves.

Metric

Deflection @ Maximum Load—The percentage represents how much a spring compresses from its original length.

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.

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 compress than steel, but can’t handle as high a load.

Corrosion-Resistant Swiveling Extension Spring Stud Anchors

These stainless steel stud anchors offer excellent corrosion resistance. The head swivels 360° so the spring stays straight and properly coiled. Attach an extension spring to an anchor and then thread the anchor into your part for a secure connection. To make tightening easier, anchors have a hex socket on the bottom and wrench flats at the top of the threads.

Slotted Spring Pins

End View

Squeeze these pins into holes and they expand slightly, creating tension to hold parts in place. They are often used as hinge pins and as fasteners for springs and power transmission components. An alternative to dowel pins, they're lighter in weight with a hollow center and don’t need a precise hole. Also known as roll pins.

Spring Steel—These pins won't deform from stress and vibration. Although they're stronger than stainless steel, they're best for dry environments since moisture will cause them to rust.

Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.
