Value Collection DPI920070 Dowel Pin 20x70mm Alloy Steel

Product Description

The VALUE COLLECTION DPI920070 is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. It measures 20mm in diameter and 70mm in overall length, with one rounded end and one threaded end for pull-out removal. The pin achieves a hardness rating of 57-63 HRC, giving it strong resistance to wear and deformation under load. This type of precision dowel pin is used to align and locate mating components in machined assemblies, jigs, fixtures, and tooling. Machinists, tool and die makers, and maintenance technicians working with precision mechanical assemblies are the primary installers of this fastener.

This dowel pin is suited for use in precision alignment applications across industrial, manufacturing, and mechanical maintenance environments. The flat vent feature allows trapped air and lubricant to escape during press-fit installation, reducing hydraulic lock and insertion force. The threaded end enables controlled extraction using a standard pull-out tool, making it appropriate for assemblies that require periodic disassembly without damage to the bore. It is commonly used in tool and die work, fixture building, machine repair, and OEM component assembly where repeatable positional accuracy is required.

Key Features

• DIN 7979D standard flat vent pull out design with one rounded and one threaded end
• 57-63 HRC hardness rating provides high wear resistance under cyclic load
• Flat vent groove reduces hydraulic lock during press-fit installation
• Alloy steel construction for strength and durability in precision tooling applications
• Threaded end allows controlled extraction without bore damage
• 20mm diameter x 70mm overall length for accurate component alignment

Compatibility

Designed as an OEM-style precision alignment fastener for use in machined bores conforming to DIN 7979D tolerances in industrial fixtures, jigs, tooling, and mechanical assemblies.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using an arbor press or hydraulic press. The mating bore should be finish-reamed to the appropriate DIN 7979D tolerance before installation. Power down all equipment and relieve any stored mechanical or hydraulic pressure before pressing the pin into position. Use the threaded end with an appropriate pull-out tool for extraction to avoid bore damage during disassembly.
