Gibraltar HCP5676-G Hard Core Pin 5/8 in Steel

Product Description

The GIBRALTAR HCP5676-G is a hard core steel pin designed for use in industrial fastening, tooling, and fixture applications where precise alignment and high hardness are required. The pin measures 5/8 inch in diameter with an overall length of 10 inches and a pin length of 9-3/4 inches. A 7/8-inch head diameter and 1/4-inch head height provide a positive stop surface during installation. Constructed from steel with a hard pin hardness rating, this pin delivers the durability and dimensional consistency that machinists and tooling professionals depend on for repetitive, load-bearing applications.

This hard core pin is suited for use in manufacturing environments, machine shops, and industrial assembly operations. It is commonly used as a locating pin, fixture pin, or alignment pin in jigs, dies, and production tooling. The headed design allows for controlled insertion depth and easy retrieval. At 0.76 pounds, the pin is solid and well-suited for bench work or press-fit applications where a hardened component is specified.

Key Features

• Hard core steel construction for strength and wear resistance in high-cycle tooling applications
• 5/8 inch pin diameter with tight dimensional tolerances for accurate alignment
• 9-3/4 inch pin length with 10 inch overall length including the head
• 7/8 inch head diameter provides a positive stop surface during insertion
• 1/4 inch head height for low-profile seating against fixture faces
• Sold individually — one pin per package

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial tooling, jig, and fixture assemblies requiring a headed hard core pin with a 5/8 inch diameter and 10 inch overall length.

Installation Notes

Hard core pins are typically installed by machinists or tool-and-die professionals using a press or mallet, depending on fit tolerance. Ensure the receiving bore is clean and free of debris before insertion. De-energize or lock out any machine or fixture before installing or removing locating pins. Do not modify the pin geometry by grinding or cutting, as this can compromise the hardness and dimensional integrity of the part.
