Gibraltar DCIH10-25 Heavy-duty Die Spring Red

Product Description

The GIBRALTAR DCIH10-25 is a heavy-duty die spring designed for use in stamping dies, punch tooling, and precision industrial fixtures. It features a 3/8 inch hole diameter, a 3/16 inch rod diameter, and a 1 inch free length. The trapezoidal wire cross-section delivers a higher load capacity in a compact envelope compared to round-wire springs of the same size. At maximum deflection of 0.37 inches, this spring handles a load of 50 pounds, with a spring rate of 133 pounds per inch. Chromium alloy steel construction gives it the fatigue resistance and dimensional consistency that toolmakers and maintenance technicians require in high-cycle applications.

This die spring is used in metal stamping, forming, and press tooling environments where consistent return force and repeatable deflection are critical. It fits standard die sets and tooling plates that accept a 3/8 inch spring pocket. The red color coding identifies it as a heavy-duty rating under both NAAMS and ISO 10243 load classification systems. It is appropriate for use in production tooling shops, tool and die maintenance programs, and OEM die assembly operations.

Key Features

• Heavy-duty load rating with 50 pound maximum deflection load and 133 pound per inch spring rate
• Trapezoidal wire shape increases load density compared to standard round-wire die springs
• Chromium alloy steel construction for high-cycle fatigue resistance
• Red color code identifies heavy-duty rating per NAAMS and ISO 10243 standards
• Compact 1 inch free length with 0.37 inch maximum deflection travel
• Manufactured to NAAMS, ISO 10243, and ISO 9001:2015 registered quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit addition for standard die sets and tooling fixtures that accept a 3/8 inch hole diameter die spring pocket with a 3/16 inch guide rod.

Installation Notes

Die springs are installed by toolmakers and tool and die technicians during die assembly or maintenance. Ensure the guide rod diameter matches the 3/16 inch specification and the spring pocket depth accommodates the compressed length before installation. Never exceed the rated maximum deflection, as overcompressing a die spring accelerates fatigue failure and can cause premature fracture. Follow applicable shop safety procedures and lock out all press energy before servicing any die tooling.
