Value Collection A996666 Flat Vent Pull Out Dowel Pin

Product Description

The VALUE COLLECTION A996666 is a flat vent pull out dowel pin manufactured from alloy steel to DIN 7979D standards. The pin measures 16 mm in diameter and 50 mm in overall length, with one rounded end and one threaded end for pull-out extraction. Hardness is rated at 57-63 HRC, providing resistance to wear and deformation under press-fit loading. This type of precision locating pin is used in tooling, fixture plates, machined assemblies, and mechanical sub-assemblies where accurate component alignment and repeatable positioning are required. Installation and removal are performed by machinists and tool and die technicians.

Flat vent pull out dowel pins are suited for close-tolerance bore applications in production tooling, jigs, dies, and precision mechanical assemblies. The flat vent groove along the pin body allows trapped air and lubricant to escape during installation, preventing hydraulic lock in blind bores. The threaded end allows controlled extraction with a standard pull-out tool, making this design particularly useful in assemblies where the pin is not accessible from the opposite side. Sold in a package quantity of 5.

Key Features

• DIN 7979D standard flat vent pull out design for close-tolerance locating applications
• 57-63 HRC hardness for wear resistance under press-fit and cyclic loading
• Flat vent groove allows air and lubricant relief in blind bore installations
• One rounded end for guided insertion, one threaded end for pull-out extraction
• Alloy steel construction for high strength in precision tooling environments
• Sold in a package of 5 pins per order

Compatibility

Designed as an OEM-style replacement or direct substitute for DIN 7979D flat vent pull out dowel pins with a 16 mm diameter and 50 mm overall length in precision tooling, fixture, and mechanical assembly applications.

Installation Notes

Installation is typically performed by machinists or tool and die technicians using a press or driving tool appropriate for the bore tolerance. Ensure the bore is clean and properly sized to the pin diameter before pressing. The flat vent groove must be oriented to allow full relief of trapped air and lubricant during seating. Use the threaded end with a compatible pull-out tool for removal to avoid bore damage.
