If a user needs screws that will last a long time with little wear and tear, go for stainless steel ones.
Stainless steel has the added corrosion resistance of carbon steel. This material offers strength and is more affordable than stainless steel. However, it is prone to rust, meaning it is most ideal for dry and controlled environments. Often, manufacturers coat these screws with zinc or black oxide to enhance corrosion resistance.
Brass is another common material for making thumb screws. It is a metal blend of copper and zinc, making it corrosion resistant. So, like stainless steel, this material makes screws ideal for outdoor and marine applications. Their resistance to rust and corrosion, plus the fact that they are non-magnetic, makes them suitable for electronic and optical devices. However, brass is not as strong as stainless or carbon steel. So, businesses should consider their customers' requirements to purchase fasteners that suit their customers' needs.
Plastic thumb screws are corrosion resistant. Therefore, they suit applications in which metal fasteners could be adversely affected by water, chemicals, or other corrosive substances. Although not as strong as metal, plastic provides sufficient durability for low-load applications. These electrically non-conductive fasteners are commonly used in electrical and electronic equipment. They are also a lightweight alternative for many applications.
Aluminum alloy thumb screws are lightweight and moderately strong. This property makes them great for aerospace and automotive industries, where the weight of the components plays a big role in how they perform. Moreover, they are corrosion resistant, and their anodized finish adds an extra layer of defense against wear. This makes them ideal for businesses selling automotive or aerospace parts.
