Gibraltar HEP3507-G Shoulder Ejector Pin 3/64 in Steel

Product Description

The GIBRALTAR HEP3507-G is a shoulder ejector pin designed for use in injection molds and die tooling applications. This pin features a 3/64-inch pin diameter, a 1/4-inch head diameter, and a 14-inch overall length, with a 13.5-inch usable pin length and a 1/2-inch shoulder length. Constructed from steel with a nitride finish, it delivers the hardness and surface durability required for high-cycle mold ejection duty. Toolmakers and mold technicians specify this pin when precise ejector alignment and consistent part release are critical to production quality.

This shoulder ejector pin is suited for plastic injection mold tooling, die casting tooling, and precision mold base assemblies in both prototype and production environments. The shoulder design provides a positive registration point within the ejector plate, maintaining pin alignment through repeated ejection cycles. It is typically installed by toolroom machinists or mold repair technicians working on press-side mold maintenance or new mold builds.

Key Features

• 3/64-inch pin diameter for fine-detail ejection in tight-tolerance mold cavities
• 14-inch overall length with 13.5-inch pin length accommodates deep mold configurations
• 1/4-inch head diameter and 1/8-inch head height for secure seating in standard ejector plates
• 1/8-inch shoulder diameter and 1/2-inch shoulder length provide precise axial registration
• Steel construction with nitride finish for improved surface hardness and wear resistance

Compatibility

Designed as an OEM-style replacement or direct-install component for standard ejector plate assemblies in injection mold and die tooling applications requiring a shoulder ejector pin with a 3/64-inch pin diameter and 14-inch overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians with the mold fully removed from the press and all hydraulic or mechanical ejection systems de-energized. Proper hole fit and surface finish in the ejector plate bore are essential for smooth pin travel and long service life. Inspect the mating bore for wear or damage before installing a replacement pin. Follow applicable shop safety procedures and toolroom practices when pressing or fitting ejector components.
