Value Collection 548685BR Dowel Pin 20x60mm Alloy Steel

Product Description

The VALUE COLLECTION 548685BR is a flat vent pull out dowel pin engineered for precision locating and alignment applications in tooling, fixtures, and machine assembly. Manufactured from alloy steel with a hardness rating of 57-63 HRC, this pin delivers the wear resistance and dimensional stability required in demanding production environments. It measures 20 mm in diameter and 60 mm in overall length, conforming to DIN 7979D standards. One end is rounded and the other end is threaded to allow pull-out removal from blind-hole applications. Machinists, tool and die makers, and industrial maintenance technicians are the primary installers of this component.

This dowel pin is suited for use in mold making, jig and fixture construction, press tool assemblies, and general precision machine work where repeatable part location is critical. The flat vent feature allows air and fluid to escape during press-fit insertion, reducing hydraulic lock and the risk of bore damage. The DIN 7979D designation indicates conformance to a recognized dimensional and tolerance standard, making this pin a direct-fit choice for applications already designed to that specification.

Key Features

• DIN 7979D standard — ensures dimensional and tolerance compliance for precision locating applications
• 57-63 HRC hardness — alloy steel construction resists wear and deformation under load
• Flat vent design — relieves hydraulic pressure during blind-hole press-fit installation
• Dual end configuration — one rounded end for insertion, one threaded end for pull-out extraction
• 20 mm diameter x 60 mm length — suited for medium-duty tooling and fixture work

Compatibility

Designed as a DIN 7979D-compliant flat vent pull out dowel pin for use in tooling, fixtures, molds, and precision machine assemblies that specify a 20 mm diameter locating pin with threaded extraction.

Installation Notes

Installation is typically performed by machinists or tool and die technicians using a press or mallet and appropriate bore alignment tooling. Ensure the receiving bore is finish-reamed to the DIN 7979D specified tolerance before pressing the pin into place. De-energize and lock out any associated machinery before servicing or replacing locating pins in an active fixture or tool assembly. The threaded end is intended for use with a standard extraction tool or slide hammer — do not attempt removal by driving from the rounded end in a blind-hole configuration.
