Die Spring: 3/4" Hole Dia, 3/8" Rod Dia, 5" Free Length, Blue MPN:103-420

Die Springs are essential components used in various machines, mechanisms or equipment requiring elastic retention, tensioning or shock absorption functions. They exert force when compressed and maintain it until released, providing efficient holding or locking of moving parts, while self-energizing upon loading for continuous operation without failure. This Spring's blue color distinguishes its usage as an extra precaution to prevent misuse or incorrect installation with 5 free length ensuring optimal functioning in its compressed state. Its dimensions of a 3/4 hole diameter and 3/8 rod diameter, coupled with robust material composition, ensure reliability in holding tightly on dies for metalforming, punching, or blanking operations within industries ranging from automotive to consumer goods manufacturing, providing excellent corrosion resistance against oils or chemical exposure and maintaining precision performance over time.
