Value Collection 548453PS Dowel Pin 12x25mm Alloy Steel

Product Description

The VALUE COLLECTION 548453PS is a flat vent pull out dowel pin engineered for precision alignment and secure positioning in mechanical assemblies. Manufactured from alloy steel and heat-treated to a hardness of 57-63 HRC, this pin delivers the wear resistance and shear strength required in demanding fixture and tooling applications. The pin measures 12 mm in diameter and 25 mm in overall length, conforming to DIN 7979D standards. One end is rounded for guided insertion, and the opposite end is threaded to allow positive extraction without damaging the bore. Machinists, tool-and-die technicians, and maintenance mechanics install these pins in production jigs, molds, and machine fixtures.

This dowel pin is suited for use in industrial manufacturing environments where repeatable part location is critical. It fits into applications requiring a standardized DIN 7979D flat vent pull out pin, including mold bases, fixture plates, and precision tooling assemblies. The flat vent design allows trapped air to escape during press-fit installation, reducing the risk of hydraulic lock in blind holes. This pin is sold individually with a minimum order quantity of 2 units.

Key Features

• DIN 7979D standard flat vent pull out design for precision alignment applications
• Alloy steel construction heat-treated to 57-63 HRC for high wear resistance
• Flat vent channel allows air to escape during press-fit installation, preventing hydraulic lock in blind holes
• Threaded extraction end enables positive pull-out without bore damage
• Rounded opposite end guides pin entry and reduces installation force
• 12 mm diameter by 25 mm length for standardized metric tooling applications

Compatibility

Designed as a DIN 7979D-compliant replacement or new-installation flat vent pull out dowel pin for metric-dimensioned mold bases, fixture plates, and precision tooling assemblies requiring a 12 mm bore diameter.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a press or appropriate driving tool to seat the pin flush or to specified depth in a reamed bore. Always de-energize and lock out machinery before servicing any fixture or tooling assembly. Use the threaded extraction end with a standard puller or threaded rod to remove the pin without damaging the bore. Do not hammer directly on the threaded end.
