Gibraltar HEP3535-G Shoulder Ejector Pin Steel Nitride

Product Description

The GIBRALTAR HEP3535-G is a shoulder ejector pin used in injection molds and die casting tooling to eject finished parts from a mold cavity. It features a 3/32 inch pin diameter, a 1/4 inch head diameter, and a 10 inch overall length, making it suited for moderate-depth mold applications. Constructed from steel with a nitride finish, it offers surface hardness and wear resistance under repeated cycling. Mold makers, toolroom machinists, and die maintenance technicians select this style of pin when a controlled shoulder depth and a positive head seating are required at the ejector plate interface.

This shoulder ejector pin is used in plastic injection molds, die casting dies, and stamping tooling where a standard straight ejector pin is not sufficient and a defined shoulder is needed to control pin position and load distribution. The nitride finish reduces galling and extends service life in high-cycle production tooling. With a 1/8 inch shoulder diameter and 1/2 inch shoulder length, it seats reliably in standard ejector plate bores. Sold individually, it is a direct replacement component for toolroom maintenance and mold repair operations.

Key Features

• Shoulder ejector design with 1/8 inch shoulder diameter and 1/2 inch shoulder length for positive plate retention
• 3/32 inch pin diameter with 9.5 inch pin length for moderate-depth mold applications
• 1/4 inch head diameter and 1/8 inch head height for proper seating at the ejector plate
• Steel construction with nitride finish for surface hardness and reduced wear
• 10 inch overall length suits a range of standard mold base configurations
• Sold as a single unit, suitable for targeted toolroom replacement work

Compatibility

Designed as an OEM-style replacement shoulder ejector pin for injection mold and die casting tooling requiring a 3/32 inch pin diameter and 10 inch overall length with a nitrided steel finish.

Installation Notes

Installation is performed by qualified toolroom machinists or mold maintenance technicians. The mold or die assembly must be fully de-energized, cooled, and safely secured before ejector pin service. Verify bore clearance and ejector plate fit before seating the pin to avoid binding or excessive play. Do not force the pin into an undersized bore, as this can damage the pin head or ejector plate.
