Hello, this is a SolidWorks question. I am wondering how to make a “threaded” hole in SolidWorks. The specifications are: – 0.635 – 8 ACME (I have found under ANSI and tap drill a 3\/8-16), but cannot find a 3\/8-8. And I don’t understand what ACME is and how to select it in the Hole Wizard. – 0.25-20 UNC – 2B is the other hole I need to create. Thank you.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To create threaded holes in SolidWorks using the Hole Wizard, follow these steps:<\/p>\n\n\n\n

For the 0.635-8 ACME Thread:<\/strong><\/h3>\n\n\n\n
    \n
  1. Understanding ACME Threads:<\/strong>
    ACME threads are a type of thread profile with a trapezoidal shape, commonly used in lead screws or for applications where power transmission is required. The “8” refers to the thread pitch (distance between threads), which in your case is 8 threads per inch.<\/li>\n\n\n\n
  2. Creating the Threaded Hole in SolidWorks:<\/strong>\n
      \n
    • Open the part in which you want to add the threaded hole.<\/li>\n\n\n\n
    • Go to the Hole Wizard<\/strong> (found in the Features<\/strong> tab).<\/li>\n\n\n\n
    • Under the Type<\/strong> selection, choose Threaded Hole<\/strong>.<\/li>\n\n\n\n
    • In the Standard<\/strong> dropdown, select ACME<\/strong> from the list. If the 3\/8-8 ACME option is not available, select a close option like 3\/8-16<\/strong>, or you can create a custom ACME thread. However, if the specific 3\/8-8 is missing, you can manually input the specifications in the custom thread section.<\/li>\n\n\n\n
    • In the Size<\/strong> dropdown, choose 3\/8<\/strong> for the hole size, and manually enter the 8 threads per inch if needed.<\/li>\n\n\n\n
    • For the End Condition<\/strong>, you can choose through hole or blind, depending on your requirement.<\/li>\n\n\n\n
    • Adjust the Depth<\/strong> and other settings accordingly and hit OK.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

      For the 0.25-20 UNC – 2B Thread:<\/strong><\/h3>\n\n\n\n
        \n
      1. Understanding UNC and 2B:<\/strong>
        UNC (Unified National Thread) refers to a standard series of threads, and the “2B” indicates the internal threading (female thread) with a medium fit. The 0.25-20 means the diameter is 0.25 inches (1\/4 inch), and the pitch is 20 threads per inch.<\/li>\n\n\n\n
      2. Creating the UNC Threaded Hole:<\/strong>\n
          \n
        • Again, open the part where the hole needs to be created.<\/li>\n\n\n\n
        • Open the Hole Wizard<\/strong>.<\/li>\n\n\n\n
        • Choose Threaded Hole<\/strong>.<\/li>\n\n\n\n
        • From the Standard<\/strong> dropdown, select ANSI Inch<\/strong>.<\/li>\n\n\n\n
        • In the Type<\/strong> dropdown, select Tap<\/strong>.<\/li>\n\n\n\n
        • For Size<\/strong>, choose 0.25-20 UNC<\/strong>. SolidWorks will automatically set the dimensions and fit for the thread type.<\/li>\n\n\n\n
        • Select the Hole Type<\/strong> as Through Hole<\/strong> or Blind Hole<\/strong>, depending on your need.<\/li>\n\n\n\n
        • Set the End Condition<\/strong> and any other parameters specific to your design.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

          Summary:<\/strong><\/h3>\n\n\n\n
            \n
          • For ACME threads, you may need to adjust the hole size and thread pitch manually if the specific size is not listed.<\/li>\n\n\n\n
          • For UNC threads, the Hole Wizard should automatically recognize the standard sizes, including 0.25-20 UNC.<\/li>\n\n\n\n
          • Use ANSI Inch<\/strong> for standard Unified threads and ACME<\/strong> for trapezoidal threads. Ensure to specify the fit and depth of the hole based on your design requirements.<\/li>\n<\/ul>\n\n\n\n
