Value Collection 548191PS Dowel Pin 5x16mm Alloy Steel Din 7979D

Product Description

The Value Collection 548191PS is a flat vent pull out dowel pin designed for precision location and alignment applications in mechanical assemblies. Manufactured from alloy steel and heat treated to a hardness of 57-63 HRC, this pin delivers high resistance to wear and deformation under load. The pin measures 5 mm in diameter and 16 mm in overall length, with one rounded end and one threaded end for positive extraction using a pull-out tool. It conforms to DIN 7979D standards. Machinists, tool and die specialists, and maintenance technicians install this type of pin where repeatable, accurate component registration is required.

This dowel pin is suited for use in jigs, fixtures, mold assemblies, and precision machine components where a flat vent channel is required to allow air and lubricant to escape during press-fit installation. The DIN 7979D specification governs the flat vent geometry and dimensional tolerances, making it appropriate for both new builds and replacement in existing assemblies dimensioned to that standard. The threaded end allows mechanical extraction without damaging the bore or surrounding material. This SKU ships as a single pin and requires a minimum order of 5 units.

Key Features

• Flat vent design allows air and fluid relief during press-fit installation, reducing hydraulic lock
• 57-63 HRC hardness provides high wear resistance and dimensional stability under cyclic loading
• One rounded end and one threaded end for tool-assisted extraction per DIN 7979D design
• Alloy steel construction suitable for high-stress fixture and tooling applications
• Conforms to DIN 7979D dimensional and tolerance standard
• 5 mm diameter x 16 mm overall length for compact precision fitment

Compatibility

Designed as a DIN 7979D-compliant replacement or new-installation dowel pin for mechanical assemblies, jigs, fixtures, and mold components requiring a 5 mm diameter pull-out style locating pin with a flat vent profile.

Installation Notes

Installation is typically performed by machinists or millwrights using a press or mallet with a proper driving tool sized to the pin diameter. Ensure the receiving bore is reamed to the correct H7 or specified tolerance before installation to achieve proper interference fit. The threaded end is intended for use with a puller tool during removal — do not drive the pin out from the threaded end using impact. Verify bore depth and alignment before pressing to avoid galling or bore damage.
