Gibraltar HEP3631-G Straight Ejector Pin 5/8 in Steel

Product Description

The GIBRALTAR HEP3631-G is a straight ejector pin designed for use in injection molds, die casting tooling, and similar precision metalworking applications. The pin features a 5/8 inch diameter shaft with an overall length of 6 inches and a usable pin length of 5.75 inches. Constructed from steel with a nitride finish, it delivers the surface hardness and wear resistance required for repetitive ejection cycles in production tooling environments. This component is installed by tool and die makers, mold builders, and precision machinists working in mold maintenance or new mold construction.

This ejector pin suits residential and commercial tooling applications where standard straight ejector pin geometry is specified. It is appropriate for use in injection mold bases and die sets requiring a 5/8 inch pin diameter. The 7/8 inch head diameter and 1/4 inch head height conform to common ejector plate pocket dimensions, making it a practical direct replacement or spare in mold repair and maintenance work.

Key Features

• 5/8 inch pin diameter for compatibility with standard ejector pin bores
• 6 inch overall length with 5.75 inch effective pin length
• 7/8 inch head diameter and 1/4 inch head height for standard ejector plate seating
• Steel construction with nitride finish for enhanced surface hardness and wear resistance
• Straight ejector pin geometry for general-purpose mold ejection applications

Compatibility

Designed as a standard straight ejector pin for use in injection molds, die casting dies, and precision tooling assemblies requiring a 5/8 inch pin diameter and 6 inch overall length.

Installation Notes

Installation is performed by qualified tool and die makers or mold technicians. Before servicing or replacing ejector pins, ensure the mold is fully cooled, de-pressurized, and the press is locked out and tagged out per applicable safety procedures. Pins should be seated properly in the ejector plate pockets with the head fully recessed to prevent interference during mold operation. Verify pin length and head dimensions against the mold specification before installation to confirm correct fitment.
