Gibraltar DCIH16-25 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH16-25 is a heavy-duty die spring engineered for high-load tooling and stamping applications. Built from chromium alloy steel with a trapezoidal wire shape, this spring delivers a spring rate of 445 pounds per inch and a maximum deflection load of 167 pounds. The compact 1-inch free length and 0.625-inch hole diameter make it a fit for confined die sets where consistent return force is critical. Identified by its red color coding per ISO 10243 heavy-duty classification, this spring is installed by tool and die makers, maintenance technicians, and industrial press operators.

This spring is suited for use in progressive dies, stamping dies, injection molds, and punch-and-die tooling assemblies. The 11/32-inch rod diameter and 0.370-inch maximum deflection allow for precise fitment in standard die spring pockets. Compliance with NAAMS and ISO 10243 standards makes it a recognized replacement option across North American and international tooling environments. The sold-as-single packaging supports maintenance replenishment and prototype builds without requiring bulk purchase.

Key Features

• Heavy-duty duty rating with 167-pound maximum deflection load and 445 pounds-per-inch spring rate
• Trapezoidal wire cross-section for higher load capacity relative to round-wire springs of similar size
• Red color coding per ISO 10243 heavy-duty classification for fast field identification
• Chromium alloy steel construction for fatigue resistance under repeated cycling
• Meets NAAMS, ISO 10243, and ISO 9001:2015 registered standards
• Sold individually — no minimum multi-pack required

Compatibility

Designed as a standard heavy-duty die spring replacement conforming to NAAMS and ISO 10243 dimensional standards, suitable for use in compatible tooling assemblies requiring a 0.625-inch hole diameter and 11/32-inch rod diameter spring pocket.

Installation Notes

Die spring replacement is typically performed by tool and die technicians or maintenance machinists. Always de-energize and lock out the press before accessing the die set. Verify that the spring pocket depth, hole diameter, and rod diameter match the spring dimensions before installation. Do not compress the spring beyond its rated maximum deflection of 0.370 inches to avoid permanent set or premature fatigue failure.
