Gibraltar HCP5677-G Hard Core Pin 3/4 in 6 in Oal Steel

Product Description

The GIBRALTAR HCP5677-G is a hard core steel pin designed for industrial and mechanical fastening applications requiring a hardened, headed pin. With a 3/4 inch pin diameter and 6 inch overall length, this pin delivers the dimensional precision and material hardness needed for reliable positioning, alignment, and retention tasks. The steel construction provides the strength and wear resistance expected in production and maintenance environments. It is typically installed by machinists, millwrights, and maintenance technicians working on machinery, fixtures, or fabrication assemblies.

This hard core pin is suited for use in manufacturing facilities, machine shops, and general industrial maintenance settings. Its hardened pin body makes it appropriate for applications where softer pins would deform or wear prematurely. The 1 inch head diameter provides a positive stop and bearing surface, making it well suited for press-fit, drive-fit, and through-hole positioning applications across a range of mechanical assemblies.

Key Features

• 3/4 inch pin diameter for heavy-duty positioning and alignment
• 6 inch overall length with 5.75 inch usable pin length
• 1 inch head diameter provides a positive stop surface
• 1/4 inch head height for low-profile seating
• Hard pin hardness rating for wear and deformation resistance
• Steel construction for strength in industrial environments

Compatibility

Designed as a standard hard core headed pin for use in industrial machinery, fixtures, and fabrication assemblies where a 3/4 inch diameter hardened pin is specified.

Installation Notes

Hard core pins of this type are typically installed by machinists or maintenance technicians using a press or mallet, depending on the fit tolerance of the receiving hole. Ensure the receiving bore is clean and properly sized before driving the pin. De-energize and lock out any equipment before performing pin installation or removal. Follow applicable workplace safety and machine guarding standards during installation.
