Made of stainless steel, these springs are more corrosion resistant than steel springs. They're also easier to extend than steel springs. As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch or millimeter of extension.

302 stainless steel springs have good corrosion resistance.

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.

Steel pins offer good strength.

18-8 stainless steel pins resist corrosion better than 420 stainless steel pins. They may be mildly magnetic.

Passivated pins offer added protection against corrosion and oxidation.

Metric pins meet ISO 8750 specifications.
