Gibraltar CP4277-G Soft Core Pin 13/32 in Steel

Product Description

The GIBRALTAR CP4277-G is a soft core pin used in workholding, jig, fixture, and tooling applications across machine shops and fabrication environments. The pin measures 13/32 inches in diameter with a 2.75-inch pin length and a 3-inch overall length. The head is 11/16 inches in diameter and 1/4 inch tall, providing a stable shoulder for indexed or flush-mount applications. Constructed from steel with a soft hardness rating, this pin is designed for applications where the pin itself — not the workpiece — is intended to absorb or yield under load or interference conditions. Machinists, tool-and-die technicians, and fixture builders are the primary installers.

This pin is suited for use in drill jigs, modular fixturing systems, and general tooling setups in both job-shop and production environments. The soft core construction makes it appropriate where easy removal, re-pinning, or replaceable locating elements are required without risk of damaging hardened receiver bores. It fits light-duty clamping and locating operations where precision alignment is needed but full hardened-pin durability is not required.

Key Features

• Soft steel construction allows pin to yield under overload, protecting fixture bores from damage
• 13/32 inch pin diameter for precise locating in standard fixture and jig bores
• 11/16 inch head diameter provides a positive shoulder seat for depth-controlled installation
• 1/4 inch head height keeps the shoulder low-profile for flush or near-flush fixture surfaces
• 3-inch overall length suits medium-depth locating and indexing applications
• Single-piece steel construction with no coatings or inserts to degrade over repeated use cycles

Compatibility

Designed as an OEM-style replacement or direct-use locating pin for standard drill jigs, modular fixturing plates, and tooling assemblies that accept a 13/32 inch diameter soft core pin with a shouldered head.

Installation Notes

Installation is typically performed by machinists or tool-and-die technicians using hand or arbor press equipment. Ensure the receiving bore is clean and free of burrs before pressing or driving the pin into position. Because the pin is soft-hardness steel, avoid hammering directly on the head without a suitable driver or drift to prevent deformation. Remove and replace any pin that shows visible bending, galling, or dimensional wear to maintain fixture accuracy.
