Value Collection 548754BR Dowel Pin 25x50mm Alloy Steel Din 7979D

Product Description

The VALUE COLLECTION 548754BR is a flat vent pull out dowel pin engineered for precision location and alignment applications in tooling, fixtures, and machined assemblies. Manufactured from alloy steel and hardened to 57-63 HRC, this pin delivers the wear resistance and dimensional stability required in demanding industrial and trade environments. It measures 25 mm in diameter and 50 mm in overall length, with one rounded end and one threaded end to facilitate controlled extraction from blind-hole installations. The threaded end allows a pull-out tool to engage the pin cleanly without damage to the surrounding bore or mating component. Machinists, tool-and-die technicians, and mechanical maintenance professionals are the primary installers.

This dowel pin is suited for use in jigs, dies, molds, fixtures, and machine frames where repeatable, tight-tolerance alignment is critical. The flat vent feature allows trapped air and lubricant to escape during pin insertion, reducing hydraulic lock in blind bores. Conforming to DIN 7979D, the pin meets a recognized international fastener standard and is appropriate for both new builds and maintenance replacements in industrial facilities, fabrication shops, and toolrooms. It is sold as an individual piece with a minimum order quantity of one.

Key Features

• Flat vent design releases trapped air and fluid during blind-hole installation, preventing hydraulic lock
• Threaded end enables clean extraction with a standard pull-out tool, protecting bore integrity
• 57-63 HRC hardness provides high wear resistance and dimensional stability under repeated load cycling
• Conforms to DIN 7979D for international dimensional and tolerance compliance
• One rounded end and one threaded end for versatile installation orientation
• Alloy steel construction suited for high-load, close-tolerance locating applications

Compatibility

Designed as a DIN 7979D-compliant replacement or new-installation dowel pin for any jig, fixture, die, or machine assembly requiring a 25 mm diameter blind-hole locating pin with flat vent and pull-out features.

Installation Notes

Installation and removal should be performed by a qualified machinist or mechanical technician familiar with precision fastener work. Ensure the receiving bore is clean, properly sized to DIN 7979D tolerances, and free of burrs before pressing the pin. Use an appropriate pull-out tool threaded to the pin end for removal — never drive the pin from the opposite end in a blind-hole application. Consult applicable facility safety and lockout-tagout procedures before servicing any assembly containing this component.
