Inch Dowel Pins

Inch dowel pins are precision alignment components manufactured in imperial dimensions, typically ranging from 1/32" to 1" in diameter. They are widely used in American and European machinery, modular fixtures, and various mechanical assemblies.

Produced in accordance with ANSI/ASME B18.8.2 standards, these pins are available in multiple materials and end configurations to meet specific application needs. When paired with proper fit-class holes (such as H7), they provide stable and repeatable positioning.

Product Features

• Manufactured in imperial sizes, supporting diameters from 1/32" to 1"

• Precision tolerances available in h6 / h7, with optional m6 (positive tolerance) versions

• Custom machining available: chamfering, double-end, internal threading, and more

• High compatibility with US and EU equipment components, easy to install

Material & Surface Treatment

• SUJ2 (Tool Steel)
  Hardness: HRC 56–62, suitable for high-precision and repeated assembly/disassembly.
  Surface finishes available: zinc plating, nickel plating, or black oxide.

• SUS304 / SUS316 (Stainless Steel)
  Excellent corrosion resistance, widely used in semiconductor, medical, and outdoor equipment.
  Passivation optional to enhance surface durability.

• SUS416 (Free-Cutting Stainless Steel)
  Offers both corrosion resistance and machinability.
  Can be heat-treated for higher hardness; surface finish options include polishing or passivation.
