Holo-krome 01020 Dowel Pin 1/8 X 2 in Alloy Steel Grade 8

Product Description

The HOLO-KROME 01020 is a standard dowel pin manufactured from Grade 8 alloy steel with a black luster finish. It measures 0.125 inches in diameter and 2 inches in overall length, with one beveled end and one rounded end per ASME B18.8.2. This pin is used to align, locate, and retain mating components in precision assemblies. The tight diameter tolerance of -0.0001 to 0.0001 inches ensures consistent fit in reamed holes. It is typically installed by machinists, maintenance technicians, and industrial assembly professionals in both production and repair settings.

This dowel pin suits general-purpose alignment and locating applications across industrial manufacturing, equipment assembly, and mechanical maintenance. The 0.125-inch diameter and 2-inch length make it appropriate for light-to-medium duty assemblies where precise component registration is required. The black luster finish provides surface protection during storage and service. It conforms to ASME B18.8.2, making it a recognized standard fastener for use wherever that specification is called out in engineering drawings or repair documentation.

Key Features

• Grade 8 alloy steel construction for high shear strength in alignment applications
• Tight diameter tolerance of -0.0001 to 0.0001 inches for precision fit in reamed holes
• One beveled end and one rounded end per ASME B18.8.2 for guided installation
• Black luster finish for surface protection
• Conforms to ASME B18.8.2 standard

Compatibility

Designed as an OEM-style standard dowel pin for use in any application calling out an ASME B18.8.2 compliant 0.125-inch diameter by 2-inch standard dowel pin in Grade 8 alloy steel.

Installation Notes

Installation is typically performed by machinists or mechanical technicians. The receiving hole must be reamed to the appropriate tolerance to achieve proper press or slip fit. Power down and de-energize all equipment before installing or removing locating pins in active machinery. Do not hammer the pin directly on the finished end surface without a suitable drift or press to avoid deforming the end geometry.
