Gibraltar HEP3527-G Shoulder Ejector Pin 5/64 in Steel

Product Description

The GIBRALTAR HEP3527-G is a shoulder ejector pin designed for use in injection mold tooling and die casting applications. It features a 5/64-inch pin diameter, a 1/4-inch head diameter, and an overall length of 14 inches. The pin is manufactured from steel with a nitride finish, which improves surface hardness and wear resistance for extended service life in high-cycle mold environments. The shoulder design provides a positive stop against the mold plate, ensuring consistent pin positioning during ejection cycles. This part is typically installed by toolmakers, moldmakers, and precision machining professionals during mold assembly or maintenance.

This shoulder ejector pin is suited for use in plastic injection molds and similar tooling setups requiring precise ejection pin placement. The 1/8-inch head height and 1/2-inch shoulder length provide controlled seating depth within the ejector plate. The 13.5-inch pin length accommodates deeper mold configurations. It is sold individually and is appropriate for both new mold builds and replacement of worn or damaged ejector pins during routine mold maintenance.

Key Features

• Shoulder design provides positive stop for consistent positioning in ejector plates
• Nitride finish increases surface hardness and extends wear life in high-cycle tooling
• 5/64-inch pin diameter with 1/8-inch shoulder diameter for precise fitment
• 1/2-inch shoulder length for controlled seating depth
• 14-inch overall length accommodates deep mold configurations
• Steel construction for durability under repeated ejection cycle loads

Compatibility

Designed as a standard shoulder ejector pin for use in injection mold tooling and die casting mold plates requiring a 5/64-inch pin diameter and 14-inch overall length configuration.

Installation Notes

Installation is performed by qualified toolmakers or moldmakers during mold assembly or preventive maintenance. Power down and lock out all associated presses and equipment before accessing the ejector plate assembly. Pins should be seated fully into the ejector plate bore without forcing; inspect the bore for wear or damage before installing a replacement pin. Follow applicable shop safety procedures and tooling manufacturer guidelines when servicing mold components.
