Gibraltar MT7676-G Straight Ejector Pin 4mm 160mm Steel

Product Description

The GIBRALTAR MT7676-G is a straight ejector pin used in injection mold tooling to push finished parts out of a mold cavity at the end of each cycle. Machined from steel with a nitride finish for surface hardness and wear resistance, this pin measures 4 mm in diameter with an overall length of 160 mm and a pin length of 157 mm. The head diameter is 8 mm with a 3 mm head height, providing positive seating in the ejector plate. It is installed and replaced by toolmakers, mold technicians, and precision machining professionals during mold maintenance or repair operations.

This ejector pin is suited for use in plastic injection molds in both production and prototype tooling environments. The straight pin geometry and standard head dimensions make it a common replacement component in ejector systems across a wide range of mold bases. It is appropriate for residential and commercial manufacturing shops requiring precision tooling components that conform to standard ejector pin dimensional conventions.

Compatibility

Designed as an OEM-style replacement straight ejector pin for plastic injection molds requiring a 4 mm pin diameter and 160 mm overall length with a standard 8 mm head.

Installation Notes

Ejector pin replacement is performed by qualified toolmakers or mold technicians. Before servicing an ejector system, confirm the injection molding machine is fully powered down, de-pressurized, and locked out per applicable safety procedures. Verify pin diameter, overall length, and head dimensions against the mold design before installation. Do not force pins into undersized bores, as this can damage the mold plate or cause pin failure during operation.
