Fractional Size Thru Hardened Alloy Dowel Pins

Precision Ground Alignment for High-Performance Assemblies

Fractional size thru hardened alloy dowel pins with hardness ratings of 50-62 HRC or 58-62 HRC are engineered for precision alignment, repeatability, and long-term durability in demanding industrial applications. These dowel pins are manufactured to exacting tolerances, ensuring accurate positioning of components in machinery, tooling, and structural assemblies. Their consistent diameter and straightness make them ideal for press-fit or slip-fit applications where alignment is critical.

Thru Hardened Alloy Steel Construction

Superior Strength and Wear Resistance

Constructed from high-quality alloy steel and thru hardened across the entire cross-section, these dowel pins deliver exceptional strength and resistance to deformation. Unlike case-hardened alternatives, thru hardened pins maintain uniform hardness throughout, ensuring consistent performance even under high shear loads and repeated use.

Hardness Range: 50-62 HRC vs. 58-62 HRC

• 50-62 HRC: Offers a balance between strength and toughness, making it suitable for applications requiring some flexibility under load.

• 58-62 HRC: Provides maximum hardness and wear resistance, ideal for high-cycle, high-precision environments where minimal wear is critical.

Fractional Sizes for Standard U.S. Applications

Available in a full range of fractional (inch) sizes, these dowel pins are designed to meet standard U.S. machining and assembly requirements. Precision grinding ensures tight diameter tolerances, allowing for consistent interference fits or slip fits depending on the application. Common diameters range from 1/16" through 1" and beyond, with varying lengths to suit diverse assembly needs.

Applications Across Industrial Sectors

Thru hardened alloy dowel pins are widely used in automotive manufacturing, aerospace components, mold and die making, and heavy equipment assembly. They are essential for locating parts, maintaining alignment in rotating or load-bearing systems, and ensuring repeatable assembly in jigs and fixtures.

Reliable Solution for Precision Fastening

For applications requiring maximum accuracy, durability, and wear resistance, fractional size thru hardened alloy dowel pins in 50-62 HRC or 58-62 HRC provide a dependable and high-performance fastening and alignment solution.
