Gibraltar MT7689-G Straight Ejector Pin 5mm 100mm Steel

Product Description

The GIBRALTAR MT7689-G is a straight ejector pin used in injection mold tooling to push finished parts out of the mold cavity at the end of each cycle. Machined from steel with a nitride finish, this pin measures 5 mm in pin diameter and 100 mm in overall length, with a 10 mm head diameter and 3 mm head height. The nitride finish improves surface hardness and wear resistance, extending service life in high-cycle mold applications. Moldmakers, toolroom machinists, and mold maintenance technicians are the primary installers of this component.

This ejector pin is suited for use in injection molds, compression molds, and similar tooling where precise part ejection is required. It is a direct fit for tooling applications calling for a 5 mm diameter straight ejector pin at 100 mm overall length. The pin is sold individually, making it practical for targeted replacement of worn or damaged pins in an existing mold base without requiring a full kit purchase.

Key Features

• Straight ejector pin geometry for standard mold ejection applications
• 5 mm pin diameter with 97 mm usable pin length
• 10 mm head diameter and 3 mm head height for positive seating in the ejector plate
• Nitride finish for improved surface hardness and wear resistance
• Steel construction for durability in repetitive high-cycle tooling environments
• Sold as a single unit with no minimum order quantity beyond one piece

Compatibility

Designed as an OEM-style replacement or spare for injection mold tooling requiring a straight ejector pin with a 5 mm pin diameter and 100 mm overall length.

Installation Notes

Ejector pin replacement and mold maintenance should be performed by a qualified moldmaker or toolroom technician. The mold must be fully cooled and all press energy locked out before disassembling the ejector assembly. Pins should be inspected for straightness before installation, as bent pins can cause drag marks, part defects, or pin breakage. Verify the replacement pin diameter and overall length match the original tooling specifications before assembly.
