Gibraltar MT7691-G Straight Ejector Pin 5mm 160mm Steel

Product Description

The GIBRALTAR MT7691-G is a straight ejector pin designed for use in injection mold tooling and die assemblies. It features a 5 mm pin diameter and a 160 mm overall length, with a 157 mm working pin length. The head measures 10 mm in diameter and 3 mm in height, providing positive seating against the ejector plate. Constructed from steel with a nitride finish, this pin offers surface hardness and wear resistance suited to repeated ejection cycles. Toolmakers and mold technicians install this component during mold build or maintenance operations.

This ejector pin is appropriate for use in plastic injection molds, die casting tooling, and precision mold assemblies where a standard straight ejector pin configuration is required. The nitride finish reduces friction at the pin-bore interface and extends service intervals in high-cycle production environments. It is sold individually and is suited for both new mold builds and replacement of worn or damaged pins during scheduled mold maintenance.

Key Features

• 5 mm pin diameter with 157 mm pin length for precise ejection stroke alignment
• 10 mm head diameter and 3 mm head height for secure ejector plate retention
• Steel construction with nitride finish for surface hardness and wear resistance
• Straight ejector pin type compatible with standard ejector plate systems
• Sold individually with a minimum order quantity of one

Compatibility

Designed as a standard straight ejector pin for use in injection mold and die tooling assemblies requiring a 5 mm pin diameter and 160 mm overall length configuration.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians during mold assembly or maintenance. The mold should be fully de-energized, cooled, and removed from the press before ejector pin service begins. Verify pin bore diameter and ejector plate thickness match the pin and head dimensions before installation. Do not force pins into undersized bores, as this can damage the bore finish or cause pin fracture.
