Gibraltar HCP5644-G Hard Core Pin 7/32 in Steel

Product Description

The GIBRALTAR HCP5644-G is a hard core pin used for securing workpieces, fixtures, and assemblies in industrial and fabrication settings. It features a 7/32 inch pin diameter and a 6 inch overall length, with a hardened steel construction designed to withstand high shear and driving forces. The 13/32 inch head diameter provides a positive bearing surface during installation, while the 5.812 inch pin length offers reliable engagement depth. This type of fastener is commonly installed by machinists, millwrights, maintenance technicians, and tool-and-die professionals working with jigs, fixtures, and precision assemblies.

Hard core pins are suited for applications requiring a driven or press-fit locating pin with a headed stop. Typical use cases include fixture alignment, hinge pinning, and machine component retention in both light manufacturing and heavy industrial environments. The hardened steel material makes this pin appropriate for repeated use in high-cycle tooling setups where soft pins would deform or wear prematurely. This pin is sold individually.

Key Features

• Hard pin hardness rating for resistance to deformation under driving and shear loads
• 7/32 inch pin diameter for precise fit in standard drilled or reamed holes
• 13/32 inch head diameter provides a positive stop during installation
• 3/16 inch head height keeps the profile low on mating surfaces
• 6 inch overall length with 5.812 inch pin body for deep engagement applications
• Steel construction for durability in industrial and tooling environments

Compatibility

Designed as an OEM-style replacement or direct-use hard core pin for industrial fixtures, jigs, and machine assemblies requiring a 7/32 inch driven locating pin.

Installation Notes

Hard core pins are typically installed by machinists or maintenance technicians using a pin press, arbor press, or hammer and punch. Ensure the receiving hole is properly sized and deburred before driving the pin to avoid galling or splitting the workpiece. Always wear appropriate eye protection when driving pins. De-energize and lock out any machinery before performing pin installation or removal on live equipment.
