Gibraltar HEP3700 Straight Ejector Pin 9/64 in Steel

Product Description

The GIBRALTAR HEP3700 is a straight ejector pin designed for use in injection mold tooling and die applications. It features a 9/64-inch pin diameter and a 14-inch overall length, making it suitable for moderate-depth mold configurations. The pin is manufactured from steel with a nitride finish, which improves surface hardness and wear resistance under repeated ejection cycles. A 1/4-inch head diameter and 1/8-inch head height provide positive seating against the ejector plate. This component is installed by toolmakers, mold technicians, and die maintenance professionals during mold assembly or pin replacement service.

The HEP3700 fits standard ejector pin retainer plates that accept a 9/64-inch diameter straight pin with a 1/4-inch head. It is suited for residential tooling shops and commercial production facilities running plastic injection molds or die casting tooling where consistent, precise ejection is required. The 14-inch length accommodates deeper mold bases without requiring custom-length pins in many common setups.

Key Features

• 9/64-inch pin diameter for precise fit in standard mold bushings
• 14-inch overall length suits moderate to deep mold base configurations
• Steel construction with nitride finish for enhanced surface hardness and wear resistance
• 1/4-inch head diameter and 1/8-inch head height for positive retention in ejector plates
• Single-piece straight ejector pin design — no assembly required

Compatibility

Designed as an OEM-style replacement straight ejector pin for standard injection mold and die tooling applications requiring a 9/64-inch pin diameter and 14-inch overall length with a 1/4-inch head.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians. The mold or die assembly must be fully powered down, de-pressurized, and secured before ejector pin service begins. Pins should be inspected for straightness and surface condition before installation, and retainer plate bores should be checked for wear or damage. Follow applicable shop safety procedures and manufacturer tooling guidelines during all mold maintenance operations.
