Gibraltar HCP5646-G Hard Core Pin Steel 3 Inch

Product Description

The GIBRALTAR HCP5646-G is a hard core pin used in fastening, assembly, and tooling applications across industrial and trade environments. Machined from steel, it features a 0.25 inch pin diameter and a 3 inch overall length. The pin includes a flanged head measuring 0.4375 inches in diameter and 0.1875 inches in height, with a usable pin length of 2.812 inches. Its hard pin hardness rating makes it suitable for demanding positioning and retention tasks. Machinists, maintenance technicians, and assembly workers are the typical installers of this component.

The HCP5646-G is suited for use in jigs, fixtures, tooling plates, and mechanical assemblies that require precise pin placement and reliable retention. Its steel construction handles standard shop floor conditions and repeated insertion and removal cycles. This pin is commonly used in light-to-medium industrial assembly, fabrication setups, and equipment maintenance scenarios where a compact, hardened locating pin is needed.

Compatibility

Designed as an OEM-style replacement or direct-fit hard core pin for tooling, fixtures, and mechanical assemblies requiring a 0.25 inch diameter steel locating pin with a 3 inch overall length.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard hand tools or a pin press. Ensure the receiving hole is clean, free of burrs, and sized to the correct tolerance before driving or pressing the pin into place. Do not exceed the design load for the pin diameter when used in shear or retention applications. Inspect the pin and receiving bore for wear or deformation during routine maintenance.
