People familiar with nuts know that there are many kinds of nuts, such as square nut, round nut, ring nut, butterfly nut, hexagon nut, etc. Then the most common one on the market is the hexagon nut, so why is the most commonly used hexagon nut? Let's see what netizens say. Hexagon nut is the crystallization of continuous practice of working people in production and life.
1. The nut is made into hexagon for convenience. On the machine, the position where the nut is installed is not abundant enough, and the space of the spanner for screwing the nut is also very narrow. Hexagon nut, only need to pull the wrench 60 degrees at a time, can slowly tighten the nut, while the quadrangle nut needs to pull 90 degrees at a time. In other words, in order to tighten the nut, the hexagon is smaller, but the octagon nut is easy to slip because of the small contact surface between the wrench and it, and is rarely used, so the hexagon nut is the most convenient to use. If you look at the wrench, the handle and opening of the ordinary wrench can form an angle of 30 degrees, so that when the place where the nut is installed is very narrow, and the wrench can not move freely, the hexagon nut, as long as you pull a nut with the wrench, turn the wrench over, pull the nut again, and pull the nut back and forth several times, you can tighten the nut.
2. To make the nut hexagonal is to make the best use of the material. Because from the strength point of view, the big nut is stronger than the small one. In the past, the nut was usually milled out of round material. For the same round bar, the material utilization rate of hexagon nut is higher than that of quadrangle nut, and the hexagon nut made of round bar of the same thickness is much larger than that of quadrangle nut. To sum up, hexagon nut is more convenient to use and can increase the utilization rate of materials. Therefore, it is the most common nut in the market
