Value Collection 548256PS Flat Vent Pull Out Dowel Pin

Product Description

The VALUE COLLECTION 548256PS is a flat vent pull out dowel pin designed for precision alignment and locating applications in machined assemblies. Manufactured from alloy steel with a hardness rating of 57-63 HRC, this pin delivers the wear resistance and dimensional stability required in tool, die, and fixture work. The 6 mm diameter and 16 mm overall length conform to DIN 7979D standards. One end is rounded for guided insertion and the opposite end is threaded to allow controlled extraction from blind-hole applications. Machinists, toolmakers, and maintenance technicians working with press-fit alignment components are the primary installers of this fastener.

This dowel pin is suited for use in precision fixtures, molds, jigs, and mechanical assemblies where repeatable part alignment is critical. The flat vent groove along the pin body allows trapped air and lubricant to escape during press-in installation, preventing hydraulic lock in blind bores. It is appropriate for both production and maintenance environments where DIN 7979D-compliant locating hardware is specified. The threaded extraction end simplifies removal without damage to the bore or surrounding material.

Key Features

• Flat vent groove prevents hydraulic lock during press-in installation in blind bores
• Threaded end allows controlled pull-out extraction without bore damage
• 57-63 HRC alloy steel hardness for wear resistance and dimensional stability
• Conforms to DIN 7979D standard for consistent fitment in DIN-spec assemblies
• Rounded lead end guides alignment during insertion

Compatibility

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

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or arbor press for controlled insertion into a reamed locating bore. Power down and de-energize any associated machinery before servicing assemblies containing these pins. Use the threaded extraction end with an appropriate pull-out tool or slide hammer adapter to remove the pin without damaging the bore. Ensure the bore diameter and tolerance conform to DIN 7979D specifications before installation.
