Holo-krome 03076 Oversized Dowel Pin 1/2x2 in Alloy Steel

Product Description

The HOLO-KROME 03076 is a military specification oversized dowel pin designed for precision alignment and locating applications in industrial and mechanical assemblies. Manufactured from Grade 4000 alloy steel with a black luster finish, this pin meets ASME B18.8.2 standards. It measures 0.5 inches in diameter and 2 inches in overall length, with one beveled end and one rounded end for controlled insertion and positive seating. Machinists, maintenance technicians, and toolmakers rely on this type of pin to maintain tight positional tolerances in jigs, fixtures, dies, and structural assemblies under demanding service conditions.

This oversized dowel pin is suited for applications where standard-diameter pins no longer provide the interference fit required due to wear or reaming of the host bore. Typical use cases include machine tool fixturing, mold and die assemblies, military and defense equipment maintenance, and heavy industrial component alignment. The alloy steel construction supports high shear loads and cyclic loading environments. It is sold individually per package with a minimum order quantity of 2 units.

Key Features

• Meets ASME B18.8.2 military specification oversized dowel pin standard
• Grade 4000 alloy steel construction for high shear strength and durability
• Black luster finish provides corrosion resistance in service environments
• One beveled end and one rounded end for guided insertion and positive seating
• 0.5-inch diameter oversized profile restores fit in worn or reamed bores
• 2-inch overall length suits a wide range of fixture and assembly depths

Compatibility

Designed as an ASME B18.8.2-compliant oversized replacement dowel pin for industrial, tooling, and military-specification assemblies requiring a 0.5-inch nominal diameter locating pin.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using an arbor press or pin driver. Always verify bore diameter and surface finish before pressing to ensure proper interference fit and avoid galling. De-energize and lock out any machinery before servicing components that contain dowel pins. Do not hammer pins directly without a proper driver to avoid damage to the chamfer or bore.
