Holo-krome 02005 Standard Dowel Pin 3x12mm Alloy Steel

Product Description

The HOLO-KROME 02005 is a standard dowel pin designed for precise alignment and location of machined components in industrial and mechanical assemblies. Manufactured from Grade 8 alloy steel with a black luster finish, this pin delivers consistent dimensional accuracy with a diameter tolerance of -0.0001 to 0.0001 inches, making it suitable for close-tolerance fixturing and assembly work. The 3 mm diameter by 12 mm overall length profile fits a wide range of light-duty to medium-duty alignment applications. One end is beveled and one end is rounded, conforming to ASME B18.8.5M and DIN 6325 standards. Machinists, toolmakers, and maintenance technicians install these pins using standard press-fit or slip-fit procedures.

This dowel pin is well suited for use in jigs, fixtures, dies, molds, and precision machine assemblies where repeatable part location is required. The ASME B18.8.5M and DIN 6325 compliance ensures interchangeability with other conforming hardware across domestic and metric manufacturing environments. Typical applications include hole-to-hole alignment of mating components, locating machine bases, and securing tooling plates in production settings. The compact 3 mm x 12 mm size is common in smaller assemblies and instrument-grade fixtures.

Key Features

• Grade 8 alloy steel construction for high shear strength and durability
• Black luster finish provides moderate corrosion resistance and surface hardness
• Tight diameter tolerance of -0.0001 to 0.0001 inches ensures precise press or slip fit
• One beveled end and one rounded end per ASME B18.8.5M and DIN 6325
• 3 mm diameter x 12 mm overall length for compact alignment applications

Compatibility

Designed as an OEM-style replacement or direct-use standard dowel pin conforming to ASME B18.8.5M and DIN 6325 specifications, compatible with any application calling for a 3 mm diameter standard dowel pin to those standards.

Installation Notes

Dowel pins are typically installed by machinists or toolmakers using an arbor press or mallet with appropriate driver tooling. Ensure the receiving hole is reamed to the correct tolerance before installation to avoid galling or deformation of the pin or bore. Power down and de-energize any equipment before servicing assemblies that contain dowel pins. Do not hammer pins directly without a proper driver to avoid damaging the end geometry.
