Gibraltar HEP3528-G Shoulder Ejector Pin 5/64 in Steel

Product Description

The GIBRALTAR HEP3528-G is a shoulder ejector pin designed for use in injection mold tooling and die sets. This pin features a 5/64-inch pin diameter, a 1/4-inch head diameter, and an overall length of 6 inches, with a 4-inch pin length and a 2-inch shoulder length. Constructed from steel with a nitride finish, it delivers surface hardness and wear resistance suited to repeated cycling in production mold environments. Machinists, toolmakers, and mold technicians use this type of pin to eject formed parts cleanly from mold cavities without damaging part geometry.

This shoulder ejector pin is appropriate for plastic injection molds, die casting tooling, and stamping dies where a shouldered design is required to seat flush against the ejector retainer plate. The shoulder provides a positive stop at the head, allowing precise pin positioning within the ejector plate assembly. The nitride finish adds case hardness that extends service life under high-cycle conditions. Sold individually, this pin suits both repair and new tooling builds.

Key Features

• Shoulder ejector pin style with positive head stop for accurate plate seating
• 5/64-inch pin diameter with 1/8-inch shoulder diameter for stepped fit in ejector plate bores
• 1/4-inch head diameter and 1/8-inch head height for standard retainer plate pockets
• 6-inch overall length with 4-inch pin length and 2-inch shoulder length
• Steel construction with nitride finish for surface hardness and wear resistance
• Sold individually with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or new-build component for injection mold ejector plate assemblies requiring a shoulder-style ejector pin with a 5/64-inch pin diameter and 6-inch overall length.

Installation Notes

Installation is performed by toolmakers or mold technicians during mold assembly or maintenance. Power down and lock out all press and mold equipment before servicing ejector components. Verify bore diameters in both the ejector plate and retainer plate match the pin shoulder and head dimensions before pressing or seating the pin. Follow applicable shop safety and tooling standards when working inside mold bases.
