Holo-krome 02077 Pull Out Dowel Pin 8x45mm Alloy Steel

Product Description

The HOLO-KROME 02077 is a standard pull out dowel pin designed for precision alignment and locating applications in mechanical assemblies. Manufactured from Grade 8 alloy steel with a black luster finish, this pin measures 8 mm in diameter and 45 mm in overall length. One end is beveled and the other is rounded, which simplifies both insertion and extraction during assembly and disassembly operations. It meets ASME B18.8.5M and DIN 6325 fastener standards, making it a reliable choice for applications where dimensional accuracy and repeatability are critical. Machinists, tool and die makers, and maintenance technicians typically work with this type of pin.

This dowel pin is suited for use in fixtures, jigs, molds, machine bases, and precision mechanical assemblies where repeatable part location is required. The pull out feature — with one beveled and one rounded end — allows the pin to be removed without specialized extraction tooling in most standard applications. It is appropriate for both production and maintenance environments across general manufacturing, metalworking, and industrial machine repair.

Key Features

• 8 mm diameter with a diameter tolerance of -0.0001 to 0.0001 inches for tight-fit precision locating
• 45 mm overall length suitable for moderate-depth alignment applications
• Grade 8 alloy steel construction for high strength and wear resistance
• Black luster finish provides corrosion resistance in typical shop environments
• One beveled end and one rounded end for easy insertion and pull-out removal
• Conforms to ASME B18.8.5M and DIN 6325 fastener standards

Compatibility

Designed as an OEM-style precision locating pin for use in fixtures, jigs, molds, and mechanical assemblies requiring ASME B18.8.5M or DIN 6325 compliant standard pull out dowel pins.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with an appropriate driver. The mating hole should be reamed to the correct tolerance before installation to ensure proper fit and alignment function. Always de-energize and lock out any associated machinery before removing or installing locating pins. Do not force an oversized pin into an under-reamed hole, as this can damage the bore or compromise alignment accuracy.
