Within the die‑mounting assembly of a progressive stamping press, the Nitto mild‑steel screw fitting fastens the die shoe to the press bed, providing a reliable anchor for the entire die stack. By threading into the pre‑drilled holes of the die base, it holds the die block, guide pins and clamp plates in precise alignment, allowing the tool to sustain the high cyclic forces generated during sheet metal forming. The screw’s moderate strength and ease of removal make it ideal for rapid die changes when different part profiles are required, reducing downtime and simplifying maintenance. Its threaded connection also permits fine adjustment of die height, which is critical for achieving consistent part thickness and edge quality. In addition to its primary role in die making, the same fitting is commonly employed in sheet‑metal stamping lines to attach stripper plates or back‑up plates to the die set, ensuring that the workpiece can be released cleanly after each stroke. This straightforward fastening solution thus underpins both the accuracy of the die and the flexibility of the production line.
