Value Collection A996630 Flat Vent Pull Out Dowel Pin

Product Description

The VALUE COLLECTION A996630 is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. It measures 6 mm in diameter and 16 mm in overall length, with one rounded end and one threaded end for extraction. The pin carries a Rockwell C 57-63 hardness rating, providing the wear resistance and shear strength required in precision locating and alignment applications. This type of dowel pin is used by machinists, tool and die makers, and maintenance technicians working on fixtures, jigs, molds, and mechanical assemblies where accurate, repeatable part positioning is critical.

Flat vent pull out dowel pins are suited for applications where a controlled air or fluid relief channel is needed between the pin and bore during installation or removal. The flat ground along the pin body creates a venting path that prevents hydraulic lock in blind holes, making press-fit and close-tolerance installations more manageable. These pins are commonly used in production tooling, die sets, machine fixtures, and precision equipment assemblies across industrial and manufacturing environments. The threaded end allows controlled extraction using a standard puller or threaded rod without marring the bore.

Key Features

• Alloy steel construction with Rockwell C 57-63 hardness for high wear resistance
• 6 mm diameter and 16 mm overall length for compact, precise locating applications
• Flat vent along pin body prevents hydraulic lock in blind-hole installations
• Threaded extraction end allows clean removal without bore damage
• Sold in packages of 25 with a minimum order quantity of 1

Compatibility

Designed as a DIN 7979D-compliant flat vent pull out dowel pin for use in precision fixtures, tooling, molds, and mechanical assemblies requiring a 6 mm nominal bore diameter.

Installation Notes

Installation and removal of hardened dowel pins should be performed by qualified machinists or maintenance technicians using appropriate press equipment or extraction tools. Always verify bore diameter and surface finish before installation to ensure proper fit class and prevent bore damage. Use the threaded extraction end with a compatible puller to remove the pin rather than driving it from behind, which can damage the bore or mating components. Follow applicable shop standards and engineering drawings for fit tolerances.
