      Materials and Processes back to top
      All Acme lead screws, 1 3/4 inches in diameter and larger, are made of special quality medium carbon steel. Acme lead screws smaller than 1 3/4 inches are made from special quality low carbon steel. Sizes with Material listed as "Stainless Steel" (on the Acme Screw Data and Part Numbers page) are made from 304 type stainless steel. Alternate acme lead screw materials are aluminum alloys, other stainless grades, and high machinability grades of carbon steel. (For more information on materials see Table 35)

      Acme lead screws are cold formed using a unique, highly accurate thread rolling process which guarantees a smooth, accurate, high quality thread. Our thread rolling process eliminates the interrupted grain flow of conventional cut threads, thereby increasing yield, ultimate, and fatigue strengths.

      Are aluminum acme screws commonly used anywhere?

      Help will be VERY appreciated!
