Holo-krome 02147 Pull Out Dowel Pin 16x90mm Grade 8

Product Description

The HOLO-KROME 02147 is a standard pull out dowel pin manufactured from Grade 8 alloy steel with a black luster finish. This pin measures 16 millimeters in diameter and 90 millimeters in overall length, with one beveled end and one rounded end to facilitate both installation and extraction. The tight diameter tolerance of -0.0001 to 0.0001 inch ensures precise location between mated components. It meets ASME B18.8.5M and DIN 6325 fastener standards, making it suitable for applications where dimensional consistency and reliable pull-out access are required. Machinists, toolmakers, and millwrights are the typical installers.

This pull out dowel pin is used in industrial machine assembly, fixture building, jig construction, and precision alignment applications. The pull out design is particularly useful in assemblies where blind holes or limited clearance make conventional drift-pin removal impractical. The beveled lead end eases insertion into close-tolerance bores, while the threaded or formed extraction feature on the opposite end allows controlled removal without damage to the surrounding component. This pin is suited for both initial assembly and repetitive disassembly in production tooling environments.

Key Features

• 16mm diameter with tight tolerance of -0.0001 to 0.0001 inch for precise locating
• 90mm overall length for deep-reach or thick-plate applications
• Grade 8 alloy steel construction for high shear strength and durability
• Black luster finish provides corrosion resistance and a consistent surface appearance
• One beveled end and one rounded end for guided insertion and tool-assisted extraction
• Conforms to ASME B18.8.5M and DIN 6325 standards for dimensional interchangeability

Compatibility

Designed as an OEM-style precision locating pin compatible with standard dowel pin bores conforming to ASME B18.8.5M and DIN 6325 dimensional specifications. Minimum order quantity is 10 units.

Installation Notes

Installation is typically performed by machinists or toolmakers using an arbor press or dead-blow mallet with appropriate bore alignment. Ensure mating bores are clean, deburred, and dimensionally verified before pressing the pin into place. Do not use impact tools that may deform the pin head or damage the bore surface. Always de-energize and lock out any machinery before servicing components that incorporate these dowel pins.
