Value Collection 548195PS Dowel Pin 5x20mm Alloy Steel Din 7979D

Product Description

The VALUE COLLECTION 548195PS is a flat vent pull out dowel pin designed for precision alignment and location applications in machined assemblies. The pin measures 5 mm in diameter and 20 mm in overall length, manufactured from alloy steel with a hardness rating of 57-63 HRC. One end is rounded for guided insertion, and the opposite end is threaded to allow extraction with a standard puller tool. This design prevents the pin from becoming trapped in blind holes. The part conforms to DIN 7979D, the international standard governing flat vent internal thread pull-out dowel pins. Machinists, toolmakers, and maintenance technicians install this type of fastener in fixture plates, die sets, and precision machine components.

This dowel pin is suited for industrial tooling, jig and fixture construction, mold and die assemblies, and general precision machine work where repeatable alignment between mated components is required. The flat vent groove along the pin body allows air and lubricant to escape during press-fit installation, reducing hydraulic lock and preventing bore damage. Applications span manufacturing facilities, machine shops, and maintenance environments where DIN 7979D-standard dowel pins are specified.

Key Features

• DIN 7979D standard flat vent internal thread pull-out design
• 57-63 HRC alloy steel construction for high hardness and wear resistance
• One rounded end for guided press-fit insertion
• One threaded end for extraction with a standard puller
• Flat vent groove reduces hydraulic lock during installation in blind holes
• 5 mm diameter x 20 mm length for use in standard DIN 7979D-spec bores

Compatibility

Designed as a DIN 7979D-standard replacement or service pin for use in fixture plates, die sets, mold bases, and precision machined assemblies calling for a 5 mm flat vent pull-out dowel pin.

Installation Notes

Installation is performed by machinists or maintenance technicians using a press or dead-blow mallet to seat the pin into a reamed, tolerance-controlled bore. Ensure the mating bore is clean and dimensionally correct per DIN 7979D specifications before installation. The threaded end must remain accessible for future extraction using an appropriately sized puller. Never drive the pin with tools that could damage the threaded extraction end.
