The GIBRALTAR HCP5638-G is a hard core pin used for fastening, alignment, and retention applications in industrial and trade settings. It features a 3/16-inch pin diameter and a 6-inch overall length, with a pin length of 5.812 inches. The head measures 3/8 inch in diameter and 3/16 inch in height. Constructed from hardened steel, this pin is designed to resist shear forces and maintain dimensional stability under load. It is sold individually and is commonly installed by millwrights, maintenance technicians, and general tradespeople working on machinery, fixtures, jigs, and structural assemblies.
The HCP5638-G suits applications requiring a driven or press-fit hard pin where a standard soft pin would deform under stress. Typical uses include machinery assembly and maintenance, fixture alignment, and industrial equipment repair. The hardened steel construction makes it appropriate for high-cycle or load-bearing positions where pin integrity is critical. It is a direct-use, single-piece component requiring no additional hardware for basic installation.
Designed as an OEM-style replacement or direct-use hard core pin for industrial machinery, fixtures, and equipment requiring a 3/16-inch diameter hardened steel pin with a 6-inch overall length.
Hard core pins are typically installed by maintenance technicians and millwrights using a hammer or arbor press. Always ensure the receiving hole is clean, properly sized, and deburred before driving the pin. Power down or de-energize equipment and relieve any stored mechanical energy before servicing pin connections. Avoid striking the pin head at an angle, as this can damage the head or cause misalignment.
