Gibraltar MT7686-G Straight Ejector Pin 4.5mm 250mm Steel

Product Description

The GIBRALTAR MT7686-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 for wear and corrosion resistance, this pin measures 4.5 mm in diameter with a 250 mm overall length and a 247 mm pin length. The 8 mm head diameter and 3 mm head height seat securely in the ejector plate. Toolmakers and mold technicians specify this pin for precision mold maintenance and new mold builds where consistent ejection force and dimensional accuracy are required.

This ejector pin is suited for use in injection mold bases across a range of plastic part geometries. It is commonly installed in ejector plate assemblies in both production tooling shops and in-house mold maintenance departments. The nitride surface treatment supports extended service life in high-cycle applications where pin wear is a routine concern. Sold individually, it is a direct replacement for worn or damaged pins of the same diameter and length class.

Key Features

• Straight ejector pin configuration for standard mold ejection applications
• 4.5 mm pin diameter with 247 mm pin length for precise fit in ejector plate bores
• Steel construction with nitride finish for improved surface hardness and wear resistance
• 8 mm head diameter and 3 mm head height for positive seating in ejector plates
• 250 mm overall length accommodates a wide range of mold stack heights
• Sold as a single unit to support exact-quantity replacement

Compatibility

Designed as an OEM-style replacement ejector pin for injection mold tooling requiring a straight pin with a 4.5 mm diameter and 250 mm overall length.

Installation Notes

Ejector pin installation and replacement is performed by qualified toolmakers or mold technicians. Before servicing the ejector assembly, de-energize and lock out the molding machine and relieve any hydraulic pressure on the ejector system. Inspect the ejector plate bore for wear or damage before installing a new pin, and verify pin length and head dimensions match the existing plate configuration. Do not modify pin dimensions in the field.
