A variety of fasteners are often used to fix individual structural elements in production and everyday life. The most popular and widely used are screws. They are produced by the industry in a large assortment. You can meet them everywhere, both in everyday life and in a wide variety of mechanisms.
What metal the screws are made of
Everything depends on the actual scope of fasteners, operating conditions and the intended static and dynamic loads. All these factors play a role in choosing the propeller that is optimal in terms of technical characteristics and cost. The most common materials for the production of popular fasteners are:
- Classic steel, additionally hardened screws.
- Coated with a protective layer of zinc to resist corrosion.
- Made of stainless steel for harsh environments.
- Aluminum, extremely lightweight screws.
- Polymer, for narrow applications.
The higher the class of screws the more expensive the product. Their manufacture requires better machine equipment and additional hardening, then the thread could resist physical wear and loads created during active operation.
Practical application
It is difficult to imagine any mechanism or product from separate parts, in the design of which there are no screws of one size or another. Unlike rivets or welds, screws can be loosened later to make repairs or restorations. Depending on the size and type of head, screws are most often used in the following areas of human activity:
- assembly and production of home and industrial furniture;
- manufacture of automobiles, agricultural machinery;
- numerous and varied electrical products;
- small and large household appliances.
Do not underestimate the importance of choosing a screw for fixing certain parts . Thanks to a wide range of sizes, you can choose the right fasteners as accurately as possible. Without the need to change the design of the product in the future.
