Holo-krome 03026 Mil Spec Oversized Dowel Pin 3/16x1.5in

Product Description

The HOLO-KROME 03026 is a military specification oversized dowel pin manufactured from Grade 4000 alloy steel with a black luster finish. Conforming to ASME B18.8.2, this pin measures 3/16 inch in diameter with an overall length of 1.5 inches and holds a diameter tolerance of 0.0010 inches. The oversized designation means the pin is engineered for tight interference fits in precision alignment applications. One end is beveled and the opposite end is rounded, which aids insertion and seating in mating holes. Machinists, toolmakers, and maintenance technicians install these pins in fixtures, jigs, dies, and mechanical assemblies where accurate component alignment and retention are required.

This dowel pin is suited for industrial and military-grade applications where standard pins do not meet dimensional or material requirements. The alloy steel construction and black luster finish provide corrosion resistance and surface hardness appropriate for high-stress, precision assemblies. Typical use scenarios include machine tool fixtures, mold alignment, and structural assembly work in both production and maintenance environments. The ASME B18.8.2 standard governs the dimensional and material requirements for this pin type, making it a recognized specification for procurement and quality control purposes.

Compatibility

Designed as an ASME B18.8.2-compliant military specification oversized dowel pin for use in precision alignment and retention applications requiring a 3/16 inch oversized fit.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet and a properly sized driver to avoid damaging the pin or bore. Ensure the receiving hole is clean, dimensionally verified, and free of burrs before pressing the pin into place. Do not hammer directly on the pin face without a driver, as this can deform the end geometry and compromise fit. Follow applicable facility safety and tooling procedures when working with press-fit components.
