Product Description:

A machine screw is a fastener that is used like any other fastener to join two or more objects. However, machine screws are unique because of their size. The American Society of Mechanical Engineers (ASME) defines machine screws as having a diameter of no more than 0.75 inches. They can be less than 0.75 inches in diameter, but no larger. As a result, machine screws are generally smaller than most other types of screws.

In addition to being 0.75 inches or less in diameter, machine screws also feature a uniform thread. What exactly does this mean? Well, screws typically have uniform or tapered threads. Uniform threads mean that the external threads (the spiral ridges on the outside of the screw) remain the same size from the top to the bottom of the screw. In contrast, tapered threads mean that the threads of the screw expand in taper or towards the bottom. Machine screws have a uniform thread that remains the same size from top to bottom.

Advantages of Machine Screws
Machine screws are often preferred over other, larger screws. Due to their small size, they offer a wider range of applications. Machine screws can be used to attach countless types of products, objects, and surfaces.

Machine screws are also available in different materials. Stainless steel is a common material used to manufacture machine screws. It is strong and durable and provides a high level of protection against rust and corrosion. Aluminium is another common material used to manufacture machine screws. Like stainless steel, it offers protection against rust and corrosion. Aluminium machine screws are not as strong as stainless steel screws, but they are also not as heavy. For applications where weight is a concern, aluminium machine screws may be preferred!

Applications

Stainless steel is a high-quality alloy steel, with corrosion resistance, high temperature resistance, beautiful and generous, low density, high strength advantages, so in all walks of life in a wide range of applications. Stainless steel maintenance and maintenance is to ensure its long-term normal use of an important part of the following stainless steel maintenance of the specific methods as well as processes.
Stainless steel maintenance methods

1, the use of physical ways to maintain:Stainless steel surface has a layer of natural film, can protect the stainless steel from corrosion in the air, therefore, to maintain the stainless steel, we should try to protect this film. In the process of use, should avoid impact scratch or collision surface, if there is a stain, you can use a soft cloth or rag to scrub, do not use sandpaper and other abrasive materials to clean.

2, the use of chemical maintenance:When the stainless steel is in a humid environment for a long time, it may be corroded, therefore, to protect the stainless steel, it is necessary to take the chemical way to maintain. You can use acid, alkali and other cleaning agents, gently wipe the surface of stainless steel, you can also use anti-corrosive agents and other special properties of the liquid, should be rinsed with water immediately after use, and then wipe the surface with a clean cloth, in order to protect the surface finish and corrosion resistance of stainless steel.
