Holo-krome 03060 Oversized Dowel Pin 3/8x1-1/4 Alloy Steel

Product Description

The HOLO-KROME 03060 is a military specification oversized dowel pin designed for precision alignment and fastening applications in demanding industrial and mechanical assemblies. Manufactured from Grade 4000 alloy steel with a black luster finish, this pin measures 3/8 inch in diameter and 1-1/4 inches in overall length. It conforms to ASME B18.8.2, the recognized standard for dowel pins used in military and commercial-grade applications. One end is beveled and one end is rounded, allowing for controlled insertion and positive seating in mating bores. Machinists, maintenance technicians, and production assemblers typically specify this pin where tight-tolerance alignment is required.

This oversized dowel pin is suited for use in jig and fixture assemblies, machine tool components, and structural alignment applications where standard-diameter pins no longer provide adequate fit due to bore wear. The oversized designation means the pin is manufactured to a diameter slightly above nominal, allowing it to restore precise alignment in worn or reamed bores without full bore replacement. It is appropriate for both original equipment manufacturing environments and repair and maintenance settings in industrial, military, and heavy equipment contexts.

Key Features

• Military specification design per ASME B18.8.2 for consistent dimensional and material compliance
• Grade 4000 alloy steel construction for high shear strength and wear resistance
• Black luster finish provides moderate corrosion resistance in industrial environments
• One beveled end and one rounded end for guided insertion and positive seating
• Oversized diameter restores alignment in bores that have worn beyond standard pin fit
• 3/8 inch diameter by 1-1/4 inch length suits a wide range of medium-duty alignment tasks

Compatibility

Designed as an OEM-style and replacement-grade oversized dowel pin for assemblies requiring ASME B18.8.2 compliant pins at 3/8 inch nominal diameter. Verify bore diameter and oversize class against actual machined bore measurements before installation.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or drift and mallet, depending on fit class and bore condition. De-energize and lock out all equipment before inserting or removing dowel pins from live assemblies. Do not force-fit a pin into an undersized bore, as this may cause bore damage or pin failure. Inspect bore geometry and surface finish before pressing the pin to ensure proper contact and alignment.
