Gibraltar MT7700-G Straight Ejector Pin 6mm 160mm Steel

Product Description

The GIBRALTAR MT7700-G is a straight ejector pin used in injection mold tooling to push finished parts out of the mold cavity after each cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 6 mm in diameter with an overall length of 160 mm, a 155 mm pin length, a 12 mm head diameter, and a 5 mm head height. It is a standard straight-type ejector pin suited for precision mold maintenance and tooling builds. Moldmakers and toolroom machinists are the primary installers of this component.

This ejector pin is intended for use in injection mold bases and progressive die tooling where a straight ejector profile is required. The nitride surface treatment improves hardness and reduces galling against the ejector pin retainer plate and guide bushings. It is a direct-fit replacement or spare for tooling applications calling for a 6 mm diameter straight ejector pin at 160 mm overall length. Sold individually, it is well suited for single-pin replacement work or low-volume tooling projects.

Key Features

• Straight ejector pin type for standard injection mold and die tooling applications
• 6 mm pin diameter with 160 mm overall length and 155 mm usable pin length
• 12 mm head diameter and 5 mm head height for positive seating in retainer plates
• Steel construction with nitride finish for improved surface hardness and wear resistance
• Sold as a single unit, compatible with low-volume replacement and prototype tooling needs

Compatibility

Designed as an OEM-style replacement ejector pin for injection mold tooling requiring a straight pin at 6 mm diameter and 160 mm overall length.

Installation Notes

Ejector pins are installed and serviced by trained moldmakers or toolroom machinists working on injection mold bases. Power down and lock out the press or molding machine before accessing the ejector assembly. Verify pin diameter and overall length against the existing retainer plate bore and ejector plate stack before installation. Do not force or hammer pins into undersized bores, as this may damage the retainer plate or distort the pin.
