Holo-krome 04106 Spiral Vent Pull Out Dowel Pin 1x3 in

Product Description

The HOLO-KROME 04106 is a spiral vent pull out dowel pin designed for precision fastening applications that require controlled alignment and easy removal. Machined from Grade 4000 alloy steel, this pin measures 1 inch in diameter and 3 inches in overall length. It features a threaded end for pull-out extraction, a black luster finish for corrosion resistance, and surface hardness rated at Rockwell C60-64 with a core hardness of Rockwell C50-58. These characteristics make it well suited for applications where locating pins must be removed repeatedly without damaging mating components. Licensed machinists, millwrights, and mechanical assembly technicians are the primary installers.

This dowel pin is used in industrial and mechanical assembly environments where precise hole-to-hole alignment is critical. The spiral vent groove allows trapped air and lubricant to escape during press-fit installation, reducing hydraulic lock and preventing bore damage. The threaded end enables controlled extraction using a standard puller or threaded rod without the need to drive the pin from the opposite side. Typical applications include jig and fixture assembly, machine tool alignment, and production tooling setups in manufacturing facilities. It is sold individually with a minimum order quantity of one.

Key Features

• Threaded end allows pull-out extraction without damage to the mating bore
• Spiral vent groove relieves hydraulic pressure and lubricant during installation
• Surface hardness of Rockwell C60-64 provides wear resistance in high-cycle applications
• Core hardness of Rockwell C50-58 maintains toughness and resistance to shear loading
• Black luster finish offers moderate corrosion protection in shop environments
• Meets ASME/ANSI B18.8.2 and MIL-S-7742 dimensional and performance standards

Compatibility

Designed as an OEM-style replacement or new-installation dowel pin for applications conforming to ASME/ANSI B18.8.2 and MIL-S-7742 standards where a 1-inch-diameter threaded pull-out spiral vent pin is specified.

Installation Notes

Installation and removal should be performed by a qualified machinist or mechanical assembly technician familiar with precision fasteners. Before installation, verify bore diameter and surface finish meet the tolerances specified in ASME/ANSI B18.8.2. Apply appropriate lubricant to the pin and bore prior to pressing to reduce galling. Use a properly sized threaded puller for extraction rather than hammering from the opposite end, which can damage the bore or pin threads.
