Gibraltar HEP3538-G Shoulder Ejector Pin 3/32 in Steel

Product Description

The GIBRALTAR HEP3538-G is a shoulder ejector pin used in injection mold tooling and die applications. It features a stepped shoulder design that provides precise alignment and positive seating within the mold plate. The pin is machined from steel with a nitride finish for improved surface hardness and wear resistance. Key dimensions include a 3/32 inch pin diameter, a 1/4 inch head diameter, and a 6 inch overall length. This type of component is installed and replaced by toolmakers, mold technicians, and die maintenance professionals working on production tooling.

Shoulder ejector pins are used in injection molding, stamping dies, and similar tooling where a standard straight ejector pin does not provide adequate locating control. The shoulder design allows the pin to be retained and guided by a counterbored hole in the ejector retainer plate. This part is suited to applications requiring a 3/32 inch working pin diameter with a 1/8 inch shoulder diameter, 2 inch shoulder length, and 4 inch active pin length within a 6 inch overall assembly length.

Key Features

• Shoulder ejector design for positive retention and alignment in mold ejector plates
• 3/32 inch pin diameter with 1/8 inch shoulder diameter and 2 inch shoulder length
• 1/4 inch head diameter and 1/8 inch head height for standard retainer plate seating
• 6 inch overall length with 4 inch active pin length
• Steel construction with nitride finish for hardness and wear resistance
• Sold individually, compatible with standard ejector retainer plate counterbore configurations

Compatibility

Designed as an OEM-style replacement or spare for injection mold ejector systems requiring a shoulder ejector pin with a 3/32 inch pin diameter and 6 inch overall length.

Installation Notes

Installation is performed by qualified toolmakers or mold technicians during mold maintenance or build. The mold or die must be fully de-energized, depressurized, and cooled before ejector plate disassembly. Verify counterbore dimensions in the ejector retainer plate match the head and shoulder geometry of this pin before installation. Follow applicable shop safety procedures and tooling documentation when servicing ejector systems.
