Holo-krome 03046 Oversized Dowel Pin 5/16 X 1 in Alloy Steel

Product Description

The HOLO-KROME 03046 is a military specification oversized dowel pin engineered for precision alignment and fastening applications in demanding environments. Manufactured from Grade 4000 alloy steel with a black luster finish, this pin measures 5/16 inch in diameter and 1 inch in overall length. It carries a diameter tolerance of 0.0010 inches, making it suitable for close-tolerance press-fit and slip-fit installations where standard-size pins are not adequate. Conforming to ASME B18.8.2, it features one beveled end and one rounded end. Machinists, toolmakers, and maintenance professionals commonly install this type of fastener in jigs, fixtures, dies, and machine components.

This oversized dowel pin is designed for applications where standard dowel pins have worn their mating holes and a larger-diameter replacement is needed to restore accurate alignment. Common uses include machine tool repair, fixture rebuilding, and precision assembly in manufacturing and maintenance operations. The beveled end aids in press-fit installation, while the rounded end facilitates alignment during assembly. This pin is well-suited for industrial machinery, aerospace tooling, and military or defense equipment applications requiring ASME B18.8.2 compliance.

Key Features

• Oversized diameter with 0.0010-inch tolerance for close-tolerance press-fit and slip-fit installations
• Grade 4000 alloy steel construction for high strength and durability in demanding service conditions
• Black luster finish provides a degree of corrosion resistance and surface protection
• One beveled end and one rounded end for easier installation and alignment
• Conforms to ASME B18.8.2 military specification standard
• Compact 5/16 x 1 inch size suits a wide range of fixture and machine component applications

Compatibility

Designed as an ASME B18.8.2-compliant oversized dowel pin for use in jigs, fixtures, dies, and precision machine components requiring a 5/16-inch oversized hole diameter.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with an appropriate driver. Ensure mating holes are reamed to the correct oversized diameter before installation to achieve proper fit. Inspect hole surfaces for burrs or debris prior to pressing the pin into place. Always de-energize and lock out machinery before replacing or installing dowel pins in active equipment.
