Gibraltar HCP5664-G Hard Core Pin 7/16 in Steel

Product Description

The GIBRALTAR HCP5664-G is a hard core pin designed for secure fastening and alignment applications in industrial, mechanical, and trade assembly work. Machined from steel, this pin measures 7/16 inches in diameter with an overall length of 3 inches, a pin length of 2-3/4 inches, and a head diameter of 11/16 inches. The head height is 1/4 inch, providing a positive stop and easy driving surface. Its hard pin construction resists deformation under load, making it a dependable choice where precision fit and durability are required. Machinists, millwrights, and maintenance technicians are the primary installers of this type of fastener.

This hard core pin is suited for use in machinery assembly, fixture building, jig and die work, and general mechanical alignment where a headed, hardened steel pin is specified. The 7/16 inch diameter and 3 inch overall length fit a range of standard bore and hole applications in both light industrial and heavy-duty settings. It is sold individually and is appropriate for both production-line use and one-off repair or fabrication tasks.

Installation Notes

Hard core pins are typically installed by machinists, millwrights, or maintenance technicians using a pin press, arbor press, or mallet with a suitable driver. De-energize or lock out all equipment before installing or removing pins per applicable OSHA lockout/tagout procedures. Ensure the receiving bore is clean and within tolerance before driving the pin to avoid damage to the pin or workpiece. Do not exceed the designed load rating of the assembly.
