Hardened Dowel Pins

At Suburban Industries, we custom manufacture hardened dowel pins in dimensions that fit virtually any customer specification. Producing these pins requires exacting techniques, including melting and refining raw materials, ingot pouring, strand casting, rolling, and heat treating. Every finished dowel pin is inspected in order to verify proper sizing and surface quality.

When most people think of dowel pins, they picture the small, round, wooden pins that come with assemble-at-home furniture. While holding furniture components in place is an important application, our hardened steel dowel pins are used for far more demanding applications.  We heat treat these pins to provide a rust-proof coating, making them a perfect fit for corrosive, mechanical, and high-friction uses. Composed of high quality materials, our hardened dowel pins are essential for alignment in numerous industrial applications.

Our dowel pins meet or exceed the industry’s most stringent standards of quality and accuracy, including strict adherence to ASME B 18.8.2 and the following qualities:

  • Hardness: RC 50-58 to RC 60 or more
  • Standard Tolerance: ± 0.0001 to ±0.0003”
  • Oversize Tolerance: ± 0.001 to ± 0.002”
  • Undersize Tolerance: ± 0.0002”
  • Chamfer Sizes: 4 – 16°
  • Length Tolerance: ± 0.010”

Durable and versatile, hardened dowel pins are essential for the best fit, alignment, and pivot capabilities for components of all kinds. These include engine blocks, large machinery, microscopes, cameras, research equipment, and more.
