Gibraltar HEP3510-G Shoulder Ejector Pin 3/64 in Steel

Product Description

The GIBRALTAR HEP3510-G is a shoulder ejector pin used in injection molds and die casting tooling to eject formed parts from the mold cavity at the end of each cycle. Machined from steel with a nitride finish, this pin measures 3/64 inches in pin diameter, with an 8 inch pin length and a 10 inch overall length. The shoulder configuration provides a positive seating surface against the ejector plate, helping maintain consistent pin positioning and reducing deflection under cyclic load. At 0.03 pounds, it is a lightweight component suited for high-cycle tooling applications. Installation is typically performed by toolmakers and mold maintenance technicians.

This shoulder ejector pin is designed for use in injection mold tooling, progressive die sets, and similar precision tooling applications found in industrial manufacturing environments. The 1/4 inch head diameter and 1/8 inch head height provide a standard shoulder interface with the ejector retainer plate. The 1/8 inch shoulder diameter and 2 inch shoulder length allow the pin to locate precisely within the mold base. It is suited for both new tooling builds and maintenance replacement applications where worn or damaged ejector pins require swap-out during scheduled tooling service.

Key Features

• Shoulder ejector pin design provides positive registration against ejector retainer plate
• Nitride finish increases surface hardness and wear resistance for extended service life
• 3/64 inch pin diameter with 8 inch pin length for deep-draw or long-reach ejection applications
• 1/8 inch shoulder diameter and 2 inch shoulder length for precise mold base location
• Steel construction suitable for high-cycle injection mold and die tooling service
• Lightweight at 0.03 pounds, compatible with densely populated ejector plate layouts

Compatibility

Designed as an OEM-style replacement or new-build component for standard injection mold ejector systems accepting shoulder ejector pins with a 3/64 inch pin diameter, 1/4 inch head diameter, and 10 inch overall length.

Installation Notes

Shoulder ejector pins are installed and serviced by qualified toolmakers or mold maintenance technicians. Before performing any pin replacement, the mold must be fully cooled, de-pressurized, and safely secured in an open position on the press or bench. Pins should be inspected for proper seating in the ejector retainer plate and aligned to their corresponding mold core holes before reassembly. Do not force pins into undersized or damaged bushings, as this can cause premature failure or mold damage.
