Value Collection 548768BR Dowel Pin 25x120mm Alloy Steel

Product Description

The VALUE COLLECTION 548768BR is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. It measures 25 mm in diameter and 120 mm in overall length, with one rounded end and one threaded end for positive extraction during disassembly. The pin carries a Rockwell hardness rating of 57-63 HRC, providing reliable resistance to wear and shear forces in precision locating applications. This type of dowel pin is installed by machinists and tool-and-die technicians in jigs, fixtures, molds, and machine assemblies where exact part registration is required.

This pin is suited for use in industrial tooling, machine tool fixtures, injection mold bases, and precision assembly fixtures. The flat vent design allows trapped air and lubricants to escape during press-fit installation, reducing hydraulic lock and the risk of bore damage. The threaded end accepts a standard extraction tool or threaded puller for clean removal without damaging the mating bore. Packaged as a single pin per unit, it is appropriate for MRO restocking and low-volume toolroom applications.

Key Features

• DIN 7979D standard flat vent pull out configuration for controlled press-fit installation and clean extraction
• 57-63 HRC hardness for high wear resistance in precision locating duties
• One rounded end and one threaded end for extraction tool engagement
• Alloy steel construction provides strength and hardness retention under repeated use
• Single-piece packaging suitable for toolroom and MRO procurement

Compatibility

Designed as a standard DIN 7979D flat vent pull out dowel pin for use in jigs, fixtures, molds, and machine assemblies requiring a 25 mm nominal bore diameter.

Installation Notes

Installation is typically performed by a machinist or tool-and-die technician using a hydraulic or arbor press. Ensure the mating bore is clean, deburred, and held to the appropriate DIN 7979D tolerance before pressing the pin. Do not drive the pin with a hammer, as this can damage the flat vent feature or distort the bore. For removal, engage a threaded extraction tool on the threaded end and apply steady, even pulling force.
