Gibraltar HCP5652-G Hard Core Pin 5/16 in Steel

Product Description

The GIBRALTAR HCP5652-G is a hard core pin used to secure or locate components in jigs, fixtures, tooling setups, and assembly applications. Machined from steel with a hardened pin body, it measures 5/16 inches in pin diameter and 3 inches in overall length, with a 2.75-inch pin length and a 1/2-inch head diameter. The 1/4-inch head height provides a positive stop against the mounting surface. Licensed machinists, toolmakers, and maintenance technicians install this type of pin in production and repair environments where precise, repeatable positioning is required.

Hard core pins are commonly used in manufacturing jigs, drill fixtures, press tools, and workholding setups where a hardened locating element is needed to maintain part alignment under repeated use. The steel construction and hard pin body resist deformation under load, making this pin suitable for both light production and maintenance applications. This part ships in single-unit quantities and is appropriate for individual replacement or small-batch tooling builds.

Key Features

• Hard steel pin body resists deformation under repeated loading
• 5/16-inch pin diameter with 2.75-inch pin length for reliable locating depth
• 1/2-inch head diameter provides a positive stop against the work surface
• 1/4-inch head height allows controlled seating depth
• 3-inch overall length suits standard jig and fixture applications
• Single-unit packaging supports individual replacement or small-batch tooling use

Compatibility

Designed as a standard hard core locating pin for use in jigs, fixtures, and tooling applications requiring a 5/16-inch diameter hardened steel pin.

Installation Notes

Hard core pins are typically installed by machinists or maintenance technicians using a press or mallet, depending on fit tolerance. Always power down or de-energize any associated machinery before servicing tooling or fixtures. Confirm bore diameter and depth before installation to ensure proper fit and seating. Do not force an oversized pin into an undersized bore, as this may damage the fixture or distort the locating feature.
