Gibraltar HCP5651-G Hard Core Pin 9/32 in Steel

Product Description

The GIBRALTAR HCP5651-G is a hard core pin used for fastening, alignment, and retention applications in industrial and mechanical assemblies. Machined from steel with a hard pin hardness rating, it measures 9/32 inches in pin diameter and 10 inches in overall length, with a usable pin length of 9.75 inches. The 7/16-inch head diameter and 1/4-inch head height provide a positive stop surface during installation. This type of pin is typically installed by machinists, millwrights, and maintenance technicians working on jigs, fixtures, tooling setups, and mechanical subassemblies.

Hard core pins like the HCP5651-G are commonly used in manufacturing environments, machine shops, and maintenance operations where a durable, reusable pin is needed for alignment or fastening. They fit into standard drilled or reamed holes and seat against a machined surface using the headed end. The steel construction handles the shear and compressive loads typical in fixture and tooling work.

Key Features

• Hard core pin hardness for durability under load
• Steel construction for strength in industrial fastening and alignment tasks
• 9/32 inch pin diameter for standard drilled or reamed hole fitment
• 9.75 inch pin length with 10 inch overall length including the head
• 7/16 inch head diameter provides a positive seating surface
• 1/4 inch head height for low-profile installation clearance

Compatibility

Designed as an OEM-style replacement or direct fitment hard core pin for industrial fixtures, jigs, tooling, and mechanical assemblies requiring a 9/32 inch diameter pin with a headed retention style.

Installation Notes

Hard core pins are typically installed by machinists or maintenance technicians using a mallet or press into a drilled or reamed hole. Ensure the mating hole diameter and depth match the pin specifications before installation. De-energize and lock out any machinery before servicing assemblies that contain these pins. Do not force the pin into undersized holes, as this may damage the workpiece or the pin head.
