Hexagon nut is used in conjunction with bolts and screws to connect the fastening mechanism. Among them, Type I hex nuts are the most widely used. Class C nuts are used on machines, equipment or structures with rough surface and low precision. Class A and Class B nuts are used for machines with smooth surface and high precision. , equipment or structure. Type II hex nuts have a thicker thickness m and are often used in applications where assembly and disassembly are often required. The thickness m of the hexagonal thin nut is thinner and is often used when the surface space of the connected member is limited.
Why are hex nuts most commonly used?
Anyone familiar with nuts knows that there are many types of nuts, such as square nuts, round nuts, ring nuts, wing nuts, hex nuts, and so on. Then the most common one on the market is the hex nut, so why is the hex nut the most common? See what netizens say.
The hex nut is the crystallization of the working people's continuous practice in production and life.
1. The nut is made into a hexagonal shape for ease of use. On the machine, the part where the nut is mounted is sometimes not sufficiently wide, and the space for the wrench that screws the nut is also quite small. The hexagonal nut can be tightened slowly by only 60 degrees at a time, and the square nut needs to be rotated 90 degrees each time. That is to say, the hexagonal shape is smaller in order to tighten the nut, but the octagonal nut is easy to slip due to the small contact surface of the wrench, and is usually rarely used, so the hexagon nut is most convenient to use. Look at the wrench. The handle and the wrench of the ordinary wrench can be angled at 30 degrees. When the nut is installed in a narrow position and the wrench can not move freely, the hex nut can be used to pull a nut. Then turn the wrench over and pull the nut again, so that the nut can be tightened by repeatedly pulling it back and forth several times.
2. The nut is made into a hexagon to maximize the use of material. Because of the strength, the large nut is stronger than the small one. In the past, the nut is usually milled from a circular material. The same round rod is used to make the hex nut. The hex nut made of high and round rods of the same thickness is much larger than the square nut.
In summary, the hex nut is more convenient to use and also increases the material usage rate, so it is most common on the market.
Definition of hex nut
The hex nut is used in conjunction with the bolt and the screw to connect the fastening mechanism. Among them, the type 1 six-nut is the most widely used. The C-class nut is used for machines, equipment or structures with rough surface and low precision. Class A and B nuts are used for smooth surface and high precision. Machine, equipment or structure. The thickness of the type 2 hex nut is thicker, and it is often used in occasions where assembly and disassembly are often required. The thickness M of the hexagonal thin nut is thinner and is often used when the surface space of the connected member is limited.
