Screw threads may be commonly seen in lots of mechanical components. They have many functions. There are various objects to have them. They can be used for fastening. Screws, nut-bolts and studs having screw threads are used for temporarily fixing one part on to a different half. They are used for becoming a member of similar to co-axial joining of rods, and tubes, and so forth. They can be used for transmission of movement and energy like lead screws of machine tools. Besides, they can be applied for conveying and squeezing materials. For example, they are in screw conveyors, injection molding machines, screw pumps, and so forth.

Screw threads may be produced by way of various strategies. The first one is casting. It solely has a few threads over a brief length. It has less accuracy and poor end. The second one is the elimination course of (machining). It is achieved by various slicing instruments in several machine tools like lathes, milling machines, drilling machines (with tapping attachment) and so on. This is extensively used for top accuracy and finish. And it's employed for extensive ranges of threads and volume of production from piece to mass production.

The third one is the forming (rolling). This technique also has many characteristics. For occasion, blanks of robust ductile metals like steels are rolled between threaded dies. Large threads are sizzling rolled adopted by ending and smaller threads are straight cold rolled to desired finish. And cold rolling attributes extra power and toughness to the threaded parts. This method is broadly used for mass production of fasteners like bolts, screws and so forth.

In addition, the grinding is also a main strategy for production of screw threads. It is often done for finishing (accuracy and floor) after performing by machining or sizzling rolling but is often employed for direct threading on rods. Precision threads on hard or floor hardened elements are completed or directly produced by grinding solely. It is employed for wide ranges of sort and measurement of threads and quantity of production.

Screw threads may be divided into various varieties based on totally different classification strategies. According to location, there are external screw threads (for instance, on bolts) and internal screw threads (for example, in nuts). There are straight (helical) (e.g., bolts, studs), taper (helical), (e.g., in drill chuck), and radial (scroll) as in self centering chuck if classified according to configuration. Additionally, there are general threads (with normally wide thread spacing), pipe threads and fantastic threads (generally for leak proof) if divided in accordance with compactness or fineness of threads.

There are still many different classifications. All in all, we can draw a conclusion that the screw threads have a really wide range of purposes. Their capabilities and characteristics deserve our research.
