Gibraltar CP4291-G Soft Core Pin 5/8 in Steel

Product Description

The GIBRALTAR CP4291-G is a soft core pin used in workholding, fixturing, and tooling applications across machine shops and fabrication environments. It features a 5/8 inch pin diameter, a 6 inch overall length, and a steel construction suited for repeated use under moderate load. The soft core designation indicates a non-hardened pin body, which allows for easier machining, modification, or press-fit installation without risk of cracking. A 7/8 inch head diameter and 1/4 inch head height provide a defined shoulder for controlled seating depth. Machinists, toolmakers, and maintenance technicians are the primary installers of this component.

This pin is used in jigs, fixtures, die sets, and general industrial tooling where a soft, machinable locating or drive pin is required. It suits both production and prototype environments. The 5-3/4 inch pin length makes it appropriate for through-hole applications in thicker workpieces or stacked fixture plates. It is sold individually and is compatible with standard pin-hole bores sized to accept a 5/8 inch nominal diameter.

Key Features

• Soft core construction allows field modification, machining, or press-fit without cracking
• 5/8 inch pin diameter for use in standard nominal-bore fixtures and tooling plates
• 6 inch overall length with 5-3/4 inch usable pin length
• 7/8 inch head diameter provides a positive shoulder for controlled insertion depth
• Steel material offers durability across repeated use in industrial environments
• Sold as a single unit with no minimum order beyond one piece

Compatibility

Designed for use in standard 5/8 inch nominal bore jigs, fixtures, and tooling components requiring a soft, non-hardened locating or drive pin.

Installation Notes

Installation is typically performed by machinists or toolmakers using a press, mallet, or hand drive depending on the fit tolerance of the bore. Power down or de-energize any associated machinery before servicing or replacing fixture pins. Verify bore diameter and pin diameter tolerance before pressing to avoid galling or misalignment. The soft core material may be further machined or modified as needed to meet specific fit requirements.
