Value Collection A996640 Dowel Pin 8x20mm Alloy Steel

Product Description

The VALUE COLLECTION A996640 is a flat vent pull out dowel pin designed for precision locating and alignment applications in mechanical assemblies. Machined from alloy steel and hardened to a Rockwell C hardness of 57-63, this pin delivers the strength and wear resistance required for demanding industrial and tooling environments. The pin measures 8 mm in diameter and 20 mm in overall length, with one rounded end and one threaded end to allow pull-out removal when press-fit into a blind hole. It conforms to DIN 7979D standards and is sold in packages of 10.

This dowel pin is suited for use in jigs, fixtures, dies, and machine tool components where repeatable, accurate part positioning is critical. The flat vent groove along the pin body allows trapped air and excess lubricant to escape during installation, preventing hydraulic lock in blind holes. It is appropriate for both light and heavy manufacturing environments where DIN-standard fastener compliance is specified by the engineer or maintenance team.

Key Features

• Flat vent groove prevents hydraulic lock in blind-hole installations
• Alloy steel construction hardened to Rockwell C 57-63 for high wear resistance
• One rounded end and one threaded end for controlled pull-out removal
• Conforms to DIN 7979D standard for dimensional and hardness compliance
• 8 mm diameter x 20 mm overall length for precise fitment in standard-tolerance bores
• Sold in a package of 10 pins

Compatibility

Designed as a DIN 7979D-compliant flat vent pull out dowel pin for use in fixtures, dies, and precision mechanical assemblies requiring an 8 mm nominal bore diameter.

Installation Notes

Installation is typically performed by maintenance technicians or toolroom machinists using an arbor press or dead-blow hammer. Ensure the receiving bore is clean, within tolerance, and lightly lubricated before pressing the pin. The flat vent groove must be oriented to allow fluid and air to escape freely. Use the threaded end with an appropriate extractor tool for removal to avoid damaging the bore or surrounding material.
