Providing the correct torsion or extension spring for your application is our most important offering. From standard springs to hard-to-find replacement springs, Industrial Spring Co. promises the right spring for your application. Let us match your requirements to the correct Industrial Spring Co. solution. The guidelines below help identify the right spring, every time... Easy as 1, 2, 3, 4.

Step 1:

Look at the end of the spring to determine the wind direction. If the end of the spring points in the clockwise direction it is a left wound. 

Step 2:

Measure the length, in inches, of ten or twenty coil of the spring that needs to be replaced. Then compare that measurement to the chart to determine the correct wire size.


Step 3:

For torsion springs, measure the inside diameter of the 1/16” of an inch.

Step 4:

Measure the overall length of the spring to the nearest quarter inch.
