Precision Springs

When strict OD and spring rate restrictions are needed, use these springs. The springs may lie flat thanks to closed and ground ends, which prevents buckling. Zinc plating gives them a slight resistance to corrosion. A compression spring pushes back to its initial length when you squeeze it. The amount of force needed for each inch of compression is known as the spring rate. Compressing the spring becomes more difficult as the spring rate increases. Precision springs enable substantially tighter tolerances and have a higher spring rate.
