Hardened Dowel Pins

Leave a Comment

Suburban makes custom hardened dowel pins!

Hardened dowel pins are durable and versatile.  They can stand up to corrosive, mechanical, and high-friction environments.  Because of this, they provide the best fit, alignment, and pivot capabilities possible.  Use hardened dowel pins in such jobs as large machinery, microscopes, cameras, and research equipment.

It’s not easy to make hardened pins.  It requires exacting work like melting and refining raw materials, ingot pouring, strand casting, rolling, and heat treating.  Suburban has the knowledge and experience necessary to do all this and more.

We harden our dowel pins by heat-treating them and providing a rust-proof coating.  All pins are made with high quality materials.  And we closely inspect every single one of our pins before shipment.  This way you can be sure to get proper sizing and exceptional surface quality.  Whatever your need, we can make a hardened dowel pin for it.

We strictly follow ASME B 18.8.2.  Our dowel pins also meet or exceed the industry’s most stringent quality standards:

  • 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”

Where are dowel pins used? You can find dowel pins in toys, machinery, and assemblies. Also, they are popular in industrial applications. Dowel pins align parts for surgical instruments and hydraulic valves; do alignment of microscopes, cameras, and other research equipment; and are in the molds and dies of small motors.

Why are dowel pins so common? There are four main reasons for the dowel pin’s popularity:
