Looking for replacement springs for a stamping die, mold, or other industrial press? This 6-pack of red, medium-load die springs might be exactly what you need. Here are the specs: Outer Diameter (OD) is 30mm (about 1.15 inches), Inner Diameter (ID) is 16mm (about 0.63 inches), and the free length (uncompressed) is 60mm (about 2.36 inches). They have a rectangular cross-section and closed ends. The color red indicates a medium load rating in the standard die spring color code (lighter loads are yellow/blue, heavier are green/brown). These are heavy-duty springs made for high-stress, repetitive applications in tool and die work, metal stamping, plastic injection molds, and similar machinery. Always double-check your machine's specifications for spring size and load rating before ordering. But if these match, having a spare pack on hand can save a lot of downtime when a spring wears out or breaks.
