Compression Springs
As you squeeze a compression spring, it pushes back to return to its original length. Rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the rate, the harder it is to compress the spring.
Springs with closed and ground ends sit flat, so they won’t buckle.

Corrosion-Resistant Compression Springs
These springs are more corrosion resistant than standard compression springs. They're also easier to compress than standard compression springs. As you squeeze a compression spring, it pushes back to return to its original length. Rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the rate, the harder it is to compress the spring.
302 stainless steel springs have good corrosion resistance.
316 stainless steel springs have excellent corrosion resistance.
Springs with closed and ground ends sit flat, so they won’t buckle.

Swiveling Extension Spring Stud Anchors
A black-oxide finish provides these steel anchors with mild corrosion resistance. The head swivels 360° so the spring stays straight and properly coiled. Attach an extension spring to a stud and then thread the stud 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
Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes. Once installed, they expand slightly, creating outward tension that holds them tight against the hole wall. These pins absorb shock and vibration in your system, and keep parts from loosening. They are often used as hinge pins, or to hold springs and power transmission components in place.
Install these pins into a hole slightly smaller than the pin diameter. They have at least one chamfered end, which means the end is angled to make insertion easier.
Breaking strength is measured as double shear, which is the amount of force required to break a pin into three pieces.
Some metric pins with the same diameter come in two different wall thicknesses. Thinner walls are more flexible, easier to install, and won’t weigh down your assembly as much as thicker pins. Layer a pin with a thin wall inside a pin with a thicker wall to increase the breaking strength. Make sure the slots are opposite one another for maximum strength.
Steel pins are strong and wear resistant.
18-8 stainless steel pins offer a balance of strength and corrosion resistance.
Passivated pins offer added protection against corrosion and oxidation.
Pins that meet specifications for ISO 8752 (formerly DIN 1481) or ISO 13337 (formerly DIN 7346) adhere to international standards for pin dimensions.
