Holo-krome 02161 Standard Dowel Pin 20mm X 100mm Grade 8

Product Description

The HOLO-KROME 02161 is a standard dowel pin manufactured from Grade 8 alloy steel with a black luster finish. It measures 20 millimeters in diameter and 100 millimeters in overall length, conforming to ASME B18.8.5M dimensional standards. One end is beveled and one end is rounded, which aids in alignment and insertion during assembly operations. This pin provides precise locating and alignment of mating components in mechanical assemblies, fixtures, and tooling. It is installed by machinists, toolmakers, and mechanical maintenance technicians in manufacturing and industrial environments where tight positional tolerances are required.

This dowel pin is suited for use in jigs, fixtures, dies, and machine tool assemblies where repeatable component alignment is critical. The Grade 8 alloy steel construction delivers the hardness and shear strength needed for high-load or precision-fit applications. The black luster finish provides a degree of surface protection. The ASME B18.8.5M standard governs the dimensional tolerances, end geometry, and surface finish requirements for this pin type, making it a direct replacement for any ASME B18.8.5M-compliant 20 mm x 100 mm standard dowel pin.

Key Features

• Conforms to ASME B18.8.5M for standardized dimensional and tolerance compliance
• Grade 8 alloy steel construction for high shear strength and hardness
• Diameter tolerance of -0.0001 to 0.0001 inches for precise press or slip fits
• One beveled end and one rounded end for guided insertion and alignment
• Black luster finish for surface protection
• 20 mm diameter x 100 mm overall length

Compatibility

Designed as an OEM-style replacement for any ASME B18.8.5M standard dowel pin with a 20 mm diameter and 100 mm overall length in industrial machinery, tooling, and mechanical assembly applications.

Installation Notes

Dowel pins are typically pressed or driven into reamed holes by a machinist or maintenance technician using an arbor press or dead-blow mallet. Ensure the mating hole is reamed to the correct tolerance class before installation to achieve the intended fit. De-energize and lock out any machinery before servicing components that use dowel pins. Do not weld, grind, or otherwise alter the pin geometry, as this will compromise the dimensional tolerance and load capacity.
