Welcome to Nauticalloy Marine Propeller Shafting

Millstock Stainless Limited has a longstanding history of supplying precision ground shafting for various applications, notably within the marine industry. In response to continuous growth and the increasing recognition of our quality, we introduced the Nauticalloy brand of marine propeller shafting grades in 2012.

Nauticalloy Precision Ground Marine Propeller Shafting offers the following benefits:

  • Sizes: Diameters ranging from 1” (25mm) to 14” (350mm).
  • Straightness: Achieving up to 0.005” Total Indicator Reading (TIR) for diameters up to 80mm; for larger diameters, we aim for 0.010” TIR.
  • Lengths: Available up to 15 meters.
  • Surface Quality: Consistent finish better than 32 Cla.
  • Customization: Cut-to-length service and made-to-order quantities.
  • Grades: A variety of Nauticalloy grades to suit different requirements.
  • Delivery: Prompt and reliable.
  • Certification: Third-party marine inspection and certification available.

Our Nauticalloy marine propeller shafting has been utilized in numerous high-profile builds, including:

  • Aussie Rules – built by Oceanfast for Greg Norman.
  • The Eclipse – constructed by Blohm and Voss
  • Ilona – crafted by the Pendennis shipyard for an unnamed American client.
