Gibraltar HCP5657-G Hard Core Pin 11/32 in Steel

Product Description

The GIBRALTAR HCP5657-G is a hard core steel pin designed for industrial and mechanical assembly applications where a driven, headed fastener is required. This pin features an 11/32-inch pin diameter and a 10-inch overall length (OAL), with a pin length of 9-3/4 inches and a 9/16-inch head diameter. The 1/4-inch head height provides a positive seating surface against the workpiece. Manufactured from steel with a hard pin hardness rating, the HCP5657-G is suited for demanding assembly, tooling, and fixture work where dimensional precision and material strength are essential. Machinists, tool and die technicians, and maintenance professionals are the typical end users.

This hard core pin is applicable in industrial manufacturing, maintenance, and tooling environments. It is used wherever a hardened, headed pin is needed to locate, retain, or align components in jigs, fixtures, and mechanical assemblies. The pin is appropriate for shop floor installation in both production and repair contexts where a driven fastener with a defined head geometry is specified.

Key Features

• 11/32-inch pin diameter for precise hole engagement
• 10-inch overall length with 9-3/4-inch usable pin length
• 9/16-inch head diameter provides a broad seating surface
• 1/4-inch head height for controlled flush or proud installation
• Hard pin hardness rating suited to driven and press-fit applications
• Steel construction for strength and durability in industrial use

Compatibility

Designed as an OEM-style hard core pin for use in industrial jigs, fixtures, tooling plates, and mechanical assemblies requiring a hardened headed pin of 11/32-inch diameter.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or hammer and appropriate pin-driving tools. Ensure the receiving hole is clean, deburred, and dimensionally matched to the pin diameter before driving. Always wear appropriate eye protection when driving pins. Confirm all machinery is fully de-energized and locked out before servicing any assembly containing this pin.
