Stripping Spring Assemblies
These Stripping Spring Assemblies, also known as Coil Springs, serve medium pressure applications such as blanking, piercing and forming dies along with many other uses. Additionally, simply drill and tap 3/8″ – 24 location holes for each assembly. (1/4″ – 20 tap for catalog A-150).
For added versatility, you can use the coil spring assembly with or without a stripper plate depending on the design. We furnish a 3/8″ – 24 x 3/4″ large flat head screw with a lock washer to retain a 1/4″ thick Stripper Plate. (1/4″ – 20 X 112″ screw for CAT. A-150 ONLY).

When using a stripper plate, caution must be used to make sure the screw does not enter the travel area, as shown in the drawing provided. Alternatively, you can use cap screws to hold the stripper plate; however, this would require a much thicker plate to accommodate the thicker head on the screw. In addition, some users save additional time and money by only attaching a portion of the Stripping Spring Assemblies to the stripper plate, provided the design is suitable.
