Why are hexagon nuts most commonly used

People familiar with nuts know that there are many kinds of nuts, such as square nuts, round nuts, ring nuts, butterfly nuts, hexagonal nuts, etc. Then the most common hexagon nut on the market is hexagon nut. Why is hexagon nut most commonly used? See what netizens say. Hexagon nut is the crystallization of the continuous practice of the working people in production and life.

1. The nut is made into hexagon for convenient use. On the machine, the position where the nut is installed is sometimes not enough, and the space of the wrench for screwing the nut is also quite narrow. Hexagonal nuts can be tightened slowly by pulling the wrench 60 degrees at a time, while quadrangular nuts need to be pulled 90 degrees at a time. In other words, in order to tighten the nut, the hexagonal nut is smaller, but the octagonal nut is easy to slip due to the small contact surface between the wrench and it. It is usually rarely used, so the hexagonal nut is the most convenient to use. Take another look at the wrench. The handle and opening of an ordinary wrench can become an included angle of 30 degrees. In this way, when the place where the nut is installed is very narrow and the wrench can not move freely, as for the hexagonal nut, as long as the wrench pulls a nut, turn the wrench over and pull the nut again, so as to pull the nut back and forth several times, the nut can be tightened.

2. The nut is made into hexagon to maximize the use of materials. Because in terms of strength, large nuts are stronger than small ones. In the past, nuts were generally milled out of circular materials. Using the same round rod to make hexagonal nuts has higher material utilization than making quadrangular nuts, and hexagonal nuts made of round rods of the same thickness are much larger than quadrangular nuts. To sum up, hexagonal nuts are more convenient to use and can increase the utilization rate of materials. Therefore, they are the most common in the market.

Definition of hexagon nut

Hexagon nuts are used together with bolts and Screws to connect fasteners. Among them, type 1 six purpose nuts are the most widely used, and grade C nuts are used on machines, equipment or structures with rough surface and low precision requirements; Grade A and B nuts are used on machines, equipment or structures with relatively smooth surface and high precision requirements. The thickness m of type 2 hexagon nut is relatively thick, which is mostly used in occasions where assembly and disassembly are often required. The thickness m of hexagon thin nut is relatively thin, which is mostly used when the surface space of connected parts is limited.
