Value Collection 548339PS Dowel Pin 8x70mm Alloy Steel Din 7979D

Product Description

The VALUE COLLECTION 548339PS is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. The pin measures 8 mm in diameter and 70 mm in overall length, with one rounded end and one threaded end for controlled extraction. Surface hardness is rated at 57-63 HRC, providing strong resistance to wear and deformation under load. This type of precision locating pin is used in jigs, fixtures, dies, and machine assemblies where accurate part alignment and repeatable positioning are required. Installation and removal are performed by machinists, tool and die makers, and maintenance technicians working on production tooling or mechanical assemblies.

The flat vent design allows air and fluid to escape the pin hole during press-fit installation, preventing hydraulic lock and reducing insertion force. The threaded end accepts a standard extraction tool, making controlled removal practical without damaging the bore or surrounding material. This pin is suited for use in precision tooling fixtures, mold bases, press tooling, and machine frames where DIN 7979D locating pin standards are specified. The 57-63 HRC hardness range is appropriate for applications demanding dimensional stability and resistance to side-loading.

Key Features

• Flat vent channel allows air relief during pin installation, preventing hydraulic lock in blind holes
• Threaded end enables clean extraction using a standard pull-out tool without bore damage
• 57-63 HRC hardness provides high wear resistance for repeated use in precision fixtures
• Manufactured to DIN 7979D standard for dimensional consistency and interchangeability
• Alloy steel construction suitable for demanding tooling and die applications

Compatibility

Designed as an OEM-style replacement or direct-fit locating pin for tooling fixtures, mold bases, and machine assemblies specifying DIN 7979D flat vent pull out dowel pins with an 8 mm diameter and 70 mm length.

Installation Notes

Installation is typically performed by a machinist or tool and die technician using a press or hand driver appropriate for precision dowel work. De-energize and lock out all equipment before servicing any assembly containing locating pins. Verify bore diameter and depth match pin specifications before installation. Use the threaded end with an appropriate extraction tool for removal to avoid bore damage or pin deformation.
