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. Spring rate is the amount of force required for every inch of compression or, for metric springs, millimeter of compression. The higher the spring rate, the harder it is to compress the spring.
316 stainless steel springs have excellent corrosion resistance.
Cobalt-nickel alloy springs have excellent corrosion resistance as well as high strength.

Press-Fit Catches for Ball-Nose Spring Plungers
Press these catches into a hole. A countersunk indentation acts as a stop for a 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
These spiral pins remain flexible after installation, so they absorb shock and vibration better than slotted spring pins. They work well in holes that are out of round. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
18-8 stainless steel pins resist corrosion better than 420 stainless steel pins. They may be mildly magnetic.
420 stainless steel pins resist wear as well as corrosion. They are magnetic.
Passivated pins offer added protection against corrosion and oxidation.
Inch pins meet ASME B18.8.2 specifications for material and dimensions.
