3/8" Springs | McMaster-Carr

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.

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.

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.

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.

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.

Plastic Compression Springs

Not just any ordinary plastic—these springs are made from Ultem PEI, which is nonmagnetic, nonconductive, and ultra chemical resistant. That makes them a common choice for sensitive imaging systems, where magnetic parts could interfere with performance. They’re also good for areas where stray electrical currents pose a risk. And unlike many metal springs, they won’t break down when exposed to strong acids or weak bases.

Precision Compression Springs

Count on these springs when accuracy and repeatability are a must. All are made to tight OD and spring-rate tolerances. They’re often used for metering, measuring, and positioning jobs that require steady pressure or exact movement.

Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.

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.

Zinc-Plated Spring Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.

Black-Phosphate-Coated Spring Steel—The dark coating creates both a finished appearance and a barrier against rust that's more durable than clear zinc plating. Stronger than stainless steel, these pins won't deform from stress and vibration.

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.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these pins won't degrade when exposed to harsh weather, salt water, and most chemicals. They're strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

Wear-Resistant 400 Series Stainless Steel—Our most wear-resistant stainless steel pins, these are good for pivoting parts that create a lot of friction. They hold up in environments that experience occasional moisture, but they're not as corrosion resistant as 18-8 and 316 stainless steel.

Press-Fit Catches for Ball-Nose Spring Plungers

Press these catches into a hole. A countersunk indentation acts as a stop for ball-nose spring plungers. Also known as ball buttons, they withstand side loads to prevent fixture damage. Made from 440C stainless steel, they're mildly chemical resistant and may be mildly magnetic.

Coiled Spring Pins

End View

The best spring pins for joining parts exposed to vibration and shock. They're often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, they flex to conform to holes that aren’t perfectly round.

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.

Heavy Duty Coiled Spring Pins

End View

Made of thicker material than our other coiled spring pins, these are about 30% stronger with the same resilience to vibration and shock. They are often used in power transmission, automation, and other assemblies with constant motion and sudden starts and stops. Because of their spiral shape, pins flex to conform to holes that aren’t perfectly round.

Carbon 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.
