A screw and a bolt see Differentiation between bolt and screw below are similar types of fastener typically made of metal, and characterized by a helical ridge, known as a male thread external thread. Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar female thread internal thread in the matching part. Screws are often self-threading also known as self-tapping where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevent pull-out. There are many screws for a variety of materials; those commonly fastened by screws include wood, sheet metal, and plastic. A screw is a combination of simple machines —it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane thread also comes to a sharp edge around the outside, which acts a wedge as it pushes into the fastened material, and the shaft and helix also form a wedge in the form of the point.

Posted by Lib Pietrantoni November 30, 4 Comments. As mentioned in our last blog post , i n order to achieve a fully optimized thread rolling process, there are two diameters that come into play: Pitch Diameter and Blank Diameter. The means by which a blank diameter is calculated will vary based on whether a straight thread or a tapered pipe thread is the end goal. In order to calculate the blank diameter for a straight thread you must first have an understanding of what the maximum and minimum pitch diameters are, as well as an understanding of the maximum and minimum of the major diameter.
