Gibraltar HEP3506-G Shoulder Ejector Pin Steel 10 Inch

Product Description

The GIBRALTAR HEP3506-G is a shoulder ejector pin manufactured from steel with a nitride finish, designed for use in injection mold tooling and die assemblies. The pin features a 3/64-inch pin diameter, a 1/4-inch head diameter, and a 10-inch overall length, making it suited for deep-cavity mold applications where precise ejection stroke is required. The nitride finish provides surface hardness and wear resistance to extend service life under repeated cycling. This component is installed and serviced by tool and die makers, moldmakers, and maintenance technicians in industrial manufacturing environments.

Shoulder ejector pins are used in plastic injection molds, die-cast tooling, and stamping dies where a larger shoulder diameter is needed to locate and support the pin within the ejector plate while the smaller pin diameter contacts the molded part. The 1/8-inch shoulder diameter and 1/2-inch shoulder length on this pin allow it to seat securely in the ejector retainer plate. It is suited for both new mold builds and replacement applications in production tooling requiring a 3/64-inch contact pin diameter.

Key Features

• 3/64-inch pin diameter for precision ejection in tight-clearance mold cavities
• 1/8-inch shoulder diameter with 1/2-inch shoulder length for positive plate retention
• 1/4-inch head diameter and 1/8-inch head height for standard ejector retainer plate seating
• 10-inch overall length with 9.5-inch pin length supports deep-cavity tooling
• Steel construction with nitride finish for wear resistance and extended cycle life

Compatibility

Designed as an OEM-style replacement or new-build component for injection mold, die-cast, and stamping tooling that requires a shoulder ejector pin with a 3/64-inch pin diameter and 10-inch overall length.

Installation Notes

Installation is performed by qualified tool and die makers or mold maintenance technicians. The mold or die assembly must be fully powered down, depressurized, and cooled before disassembly of the ejector plate. Verify that the ejector retainer plate bore matches the shoulder diameter and head dimensions before pressing the pin into position. Do not modify the pin geometry by grinding the head or shoulder, as this may compromise plate retention and ejection function.
