Die Spring: 3/4" Hole Dia, 3/8" Rod Dia, 2" Free Length, Green MPN:9-1208-11

A die spring is a type of spring made from flat strip steel that's cold formed into a loop to create compressive force when inserted into an opening machined to precise tolerances in die blocks. One such die spring has a hole diameter of 0.75 inches, rod diameter of 0.375 inches, free length of two inches, and is manufactured with green oil tempered material that provides consistent performance across different temperatures. The unique design of die springs allows them to handle higher loads than conventional helical coil springs while occupying less space within the die block, making them ideal for compact dies in automotive, aerospace, and medical device manufacturing industries where dimensional precision is critical for quality parts production. Aside from their compact design, die springs are known for their reliability in high-cycling applications thanks to their robust construction and consistent material properties.
