Value Collection 548333PS Dowel Pin 8x50mm Alloy Steel Din 7979D

Product Description

The VALUE COLLECTION 548333PS is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. The pin measures 8 mm in diameter and 50 mm in overall length, with one rounded end and one threaded end to allow mechanical extraction from blind holes. Hardness is rated at 57-63 HRC, providing the wear resistance and press-fit retention required in precision tooling, fixture, and machine assembly applications. This pin is sold individually but must be ordered in multiples of 5.

Flat vent pull out dowel pins are used in tool-and-die work, mold making, fixture building, and general machine assembly where close-tolerance alignment is critical. The flat vent groove along the body allows trapped air and lubricant to escape during press-in installation, reducing hydraulic lock. The threaded end enables controlled removal using a standard extraction tool or slide hammer, making this pin well suited for maintenance-intensive fixtures and dies where components are regularly disassembled and reset.

Key Features

• DIN 7979D standard construction for consistent dimensional tolerances
• Flat vent groove prevents hydraulic lock during press-in installation
• Threaded end allows controlled mechanical extraction from blind holes
• 57-63 HRC hardness rating supports high-load, wear-resistant applications
• One rounded end and one threaded end for directional installation
• Alloy steel construction for strength and durability in industrial environments

Compatibility

Designed as a DIN 7979D compliant flat vent pull out dowel pin suitable for use in tool-and-die, mold, fixture, and precision machine assembly applications requiring an 8 mm diameter alignment pin with extraction capability.

Installation Notes

Installation and removal of press-fit dowel pins is typically performed by machinists, tool-and-die makers, or maintenance technicians. Power down and de-energize all equipment before servicing any fixture or assembly containing dowel pins. Use a properly sized arbor press or hydraulic press for controlled installation; avoid impact driving, which can damage the vent groove or alter bore tolerance. For extraction, thread a compatible puller into the threaded end and apply steady, axial pull force to avoid bore damage.
