Gibraltar HCP5778 Hard Core Pin 27/64 in 14 in Steel

Product Description

The GIBRALTAR HCP5778 is a hard core pin used for alignment, assembly, and fastening applications in industrial and mechanical work. It features a 27/64 inch (0.4219 inch decimal) pin diameter and a 14 inch overall length, making it well suited for through-hole alignment tasks that require reach and precision. The steel construction provides the strength and durability needed for repeated use in production and maintenance environments. A 11/16 inch head diameter and 1/4 inch head height allow positive seating against mating surfaces. This type of pin is typically installed by machinists, maintenance technicians, and industrial tradespeople working with fixtures, jigs, and assembly tooling.

The HCP5778 is appropriate for use in applications where a headed, fixed-diameter locating or drive pin is required. Its 14 inch length accommodates deeper assemblies or fixtures where standard shorter pins would not reach. The steel material makes it compatible with metal-on-metal applications in moderate to heavy-duty shop and field service environments. This pin ships individually and is sold as a single unit per package.

Installation Notes

Hard core pins are typically installed and removed by maintenance technicians or machinists using a pin press, hammer, or driver appropriate for the application. Ensure the receiving hole is clean and free of burrs before driving the pin to avoid galling or misalignment. Consult the equipment manufacturer's documentation for press-fit tolerances and removal procedures before installation.
