Wide application: Hexagonal nuts are a commonly used type of hardware in daily life, and they are a standard accessory.
Strong fastening force: Hexagonal nuts have a relatively strong fastening force and can provide a stable connection force.
Operating space requirements: When installing a common hexagon socket nut, there should be sufficient operating space to facilitate the use of tools such as adjustable wrenches, open-end wrenches or spectacle wrenches.
Installation convenience: The cylindrical head Allen nut is operated with an Allen wrench, making installation relatively convenient. It is suitable for various structures and has a neat appearance.
Thickness difference: The thickness of different types of hexagonal nuts varies. For instance, the thickness of GB6170 is thicker than that of GB52, GB6172 and DIN934, commonly known as thick nuts.
Dimensional standards: Hexagonal nuts have clear dimensional standards. For instance, GB3098.2 specifically stipulates the height of Type I and Type II hexagonal nuts.
Application scenarios: Type I hexagonal nuts are the most widely used, while grade C nuts are used in situations where the surface is rough and the precision requirements are not high. Grade A and Grade B nuts are used in machines, equipment or structures with smooth surfaces and high precision requirements.
In conclusion, hexagonal nuts are widely used in mechanical manufacturing and maintenance due to their strong fastening force and convenient operation. Meanwhile, different types of hexagonal nuts are suitable for different application scenarios and technical requirements.
