Gibraltar HEP3586-G Straight Ejector Pin 1/4 in Steel

Product Description

The GIBRALTAR HEP3586-G is a straight ejector pin used in injection molding and die casting 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 0.25 inches in diameter with an overall length of 10 inches and a usable pin length of 9.812 inches. The head measures 0.4375 inches in diameter and 0.1875 inches in height. Mold makers, tooling technicians, and die shop professionals install these pins as standard components in ejector plate assemblies.

This ejector pin is suited for use in plastic injection molds, compression molds, and die casting tooling across both prototype and production environments. Its straight geometry and standard head profile make it a common fit for ejector retainer plate systems in general-purpose mold bases. The nitride surface treatment reduces galling and extends service life in high-cycle applications. This pin is sold individually and is appropriate for maintenance replacement or new tooling builds where a 0.25 inch pin diameter is specified.

Compatibility

Designed as a standard-geometry replacement or new-build ejector pin for injection mold and die casting ejector plate systems requiring a 0.25 inch pin diameter and 10 inch overall length.

Installation Notes

Installation is performed by mold makers or tooling technicians during mold assembly or preventive maintenance. The ejector plate assembly must be fully disengaged and the molding machine must be powered down and locked out before pin replacement. Pins should be inspected for straightness and surface condition before installation, as a bent or scored pin can damage the mold plate bore. Always verify pin diameter and length against the mold specification sheet before fitting.
