Does anybody know what is 1/4-20 UNC mean? I know it is a circle that got cut but don't know does it cut through all or not nor the diameter of the circle.
1/4 inch bolt, 20 threads per inch, coarse
Thank you
The term "1/4-20 UNC" refers to a particular type of screw thread commonly used in the United States. Let's break down what each part of the term means:
1/4: This refers to the diameter of the screw. In this case, "1/4" means that the screw has a diameter of 1/4 inch.
20: This number refers to the number of threads per inch. It indicates the pitch or the distance between each thread of the screw.
UNC: UNC stands for "Unified Coarse Thread." It is a standard thread type commonly used for general-purpose applications where quick assembly and disassembly are required.
Now coming to your question about a circle that got cut, the reference to a cut circle is not directly related to the term "1/4-20 UNC." This term specifically describes the characteristics of a screw thread and does not involve cutting a circle.
If you have a specific context regarding a circle being cut, it would be helpful to provide more details so I can assist you better in understanding its significance and dimensions.
