Holo-krome 03042 Oversized Dowel Pin 1/4x2 Alloy Steel

Product Description

The HOLO-KROME 03042 is a military specification oversized dowel pin manufactured from Grade 4000 alloy steel with a black luster finish. It measures 1/4 inch in diameter and 2 inches in overall length, conforming to ASME B18.8.2 dimensional standards. One end is beveled and the opposing end is rounded, providing controlled entry and positive seating during installation. At 0.028 pounds per unit, this pin is built for precision alignment applications where standard dowel tolerances are insufficient. Machinists, tool and die makers, and mechanical assemblers working on military or heavy-duty industrial assemblies rely on this part where tight interference fits and dimensional repeatability are required.

This oversized dowel pin is suited for precision alignment and locating tasks in military specification assemblies, jigs, fixtures, and machine components. Oversized pins are specified when bore wear or initial engineering tolerances demand a tighter interference fit than standard dowel diameters provide. The ASME B18.8.2 standard ensures dimensional interchangeability with other compliant components across defense and industrial applications. The black luster finish provides a degree of corrosion resistance appropriate for controlled-environment machining and assembly work.

Key Features

• Meets military specification and ASME B18.8.2 fastener standard for dimensional compliance
• Oversized diameter provides tighter interference fit in worn or precision-critical bores
• One beveled end for guided entry; one rounded end for positive seating
• Grade 4000 alloy steel construction for strength in demanding alignment applications
• Black luster finish for corrosion resistance in controlled environments

Compatibility

Designed as an OEM-compatible replacement or new-installation dowel pin for assemblies requiring ASME B18.8.2 military specification oversized dowel pins with a 1/4-inch diameter and 2-inch length.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using a press or mallet with a proper driving tool sized to the pin diameter. Always verify bore diameter and surface finish before pressing to avoid galling or seizing. Power down and de-energize any machinery before servicing alignment components. Refer to the applicable engineering drawing and ASME B18.8.2 specification for fit class and tolerance requirements.
