Gibraltar HCP5665-G Hard Core Pin 7/16 in Steel

Product Description

The GIBRALTAR HCP5665-G is a hard core steel pin used in workholding, fixturing, and tooling applications across industrial and trade settings. It features a 7/16-inch pin diameter and a 6-inch overall length, with a hardened steel construction designed to hold up under repeated use and loading. The 11/16-inch head diameter and 1/4-inch head height provide a positive seating surface for secure positioning. Machinists, toolmakers, and maintenance technicians install this type of pin in jigs, fixtures, and alignment applications where a durable, dimensionally consistent pin is required.

This hard core pin is suited for use in light industrial and manufacturing environments wherever a precise, hardened locating or stop pin is needed. Typical applications include fixture assembly, machine setup, and component alignment on shop floors and in maintenance operations. Its steel construction and hard rating make it appropriate for demanding repetitive-use scenarios. Sold as a single unit per package.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using standard hand tools or a press fit depending on bore tolerance. Ensure the receiving bore is clean and free of debris before driving or pressing the pin into position. Inspect the seating surface and head contact area for burrs prior to installation. Follow applicable shop safety procedures when working with hardened pins under press or impact load.
