Holo-krome 04060 Spiral Vent Pull Out Dowel Pin Alloy Steel

Product Description

The HOLO-KROME 04060 is a spiral vent pull out dowel pin manufactured from Grade 4000 alloy steel with a black luster finish. It measures 0.5 inches in diameter and 1.25 inches in overall length. The threaded end allows controlled extraction during disassembly, making it practical for precision-location applications where the pin must be removed without damaging the workpiece. Surface hardness is rated Rockwell C60-64, with a core hardness of Rockwell C50-58, providing the combination of wear resistance and toughness required in high-cycle tooling and fixture work. This pin is manufactured to ASME/ANSI B18.8.2 and MIL-S-7742 standards.

This dowel pin is suited for use in jigs, fixtures, dies, and precision assemblies where repeatable alignment is critical. The spiral vent groove relieves hydraulic pressure during press-fit installation, reducing the risk of hole damage or pin galling. Machinists, tool and die makers, and maintenance technicians working in manufacturing, fabrication, and industrial maintenance environments are the primary installers. It is sold as a single piece per package with a minimum order quantity of one.

Key Features

• Spiral vent groove relieves hydraulic pressure during press-fit installation
• Threaded end allows pull-out extraction without damaging mating components
• Surface hardness Rockwell C60-64 for wear resistance in high-cycle applications
• Core hardness Rockwell C50-58 for toughness and resistance to impact loads
• Meets ASME/ANSI B18.8.2 and MIL-S-7742 dimensional and performance standards
• Black luster finish for corrosion inhibition during storage and service

Compatibility

Designed as an OEM-style replacement or direct-use spiral vent pull out dowel pin for precision fixtures, jigs, dies, and tooling assemblies requiring a 0.5-inch diameter press-fit locating pin with threaded pull-out capability.

Installation Notes

Installation is typically performed by machinists or tool and die technicians using a press or mallet with an appropriate driver. Ensure the receiving hole is clean, burr-free, and sized to the correct interference fit per ASME/ANSI B18.8.2 specifications before pressing the pin into place. De-energize and lock out any machinery before servicing fixtures or tooling that incorporate dowel pins. Use the threaded end with a standard pull-out tool or threaded rod for removal to avoid damage to the pin or bore.
