If you are looking for more information on machine screws then, you’ve come to the right place.
Machine Screws In A Nutshell
Examples Of Machine Screws
One of the most useful varieties of screws available in the market is the machine screw. These screws serve multiple purposes and are extremely handy around the house. Simply put, machine screws are a variety of fasteners that are made with uniform threads and their diameter is usually ΒΌ of an inch or even less than that. The screws are supposed to be used by threading them through nuts or holes, which too are uniformly threaded. Machine screws serve the purpose of fasteners.
For ease of use, these screws are available in a variety of sizes, materials, driver head styles and even configurations. Depending on the purpose to be served, you can choose from a variety of materials such as brass, nylon, stainless steel, aluminum and so on. There are a variety of head types to choose from as well. For example, you can use the square drive socket head and security heads that are easy to fasten but extremely tough to extract, or the hex socket head that is paired for use with Allen wrenches or even the regular slotted head type.
The primary purpose of these is to secure different fractions of appliances, vehicles, devices, tools, and machines and hold them together.
What Is The Purpose Of Uniform Threads In Machine Screws?
One of the trademark features of these screws is that they are made with uniform threading techniques. These threads are installed to fulfill a specific purpose in the functionality of the fasteners. The uniform threads help in retaining a homogenous, equal diameter across the full length of the threaded parts of the screw. This kind of threading is in direct contrast to tapered threads because the latter serve the purpose of getting threaded into the material by the screw itself whereas in uniform threading it remains affixed to the fastener.
Different Types Of Machine Screw Heads
Usually the method of die cutting is used for building the uniform threads. A portion of the material used in the threads is actually extracted from the grooves that form a part of the thread. In other cases extreme pressure is used and rolling dies are embedded into the screws without removing any material from the main screw body itself.
Ways In Which Machine Screws Can Be Used For Fastening
Machine screws serve a number of purposes and are extremely functional. They can be used for fastening different kinds of objects. There are a number of ways in which these screws can be fastened as well.
For example these screws can be put through two or more factions of a piece and then pushed through the final part which serves the function of a nut in the system. Or these screws can be used to attach two or more pieces together by being pushed into holes and then being affixed with a corresponding nut.
These screws can also be used in terminal strips and electrical connections. One can also use them to hold together PEM brand fasteners where the metal inserts are driven directly into the plastic pieces. Machine screws can also be used in gasket style appliances and devices.
Difference Between Bolts And Machine Screws
Comparison Between Machine Screws And Bolts
Given the similarity in functionality between machine screws and bolts, a comparison between the two is common. Let us take a look at the two different types of fasteners.
To begin with, the primary difference is in terms of size. Bolts are ordinarily larger in size and diameter as compared to the machine screw.
In terms of usage, machine screws are utilized in instances where the method of fastening can be achieved by rotating the head of the screw and fastening the different components together. Bolts come into play in cases where the fastening has to be achieved by rotating the nut affixing the bolt.
