Why Are Hexagon Nuts Most Commonly Used?

Mar. 20, 2020

Those who are familiar with nuts know that there are many types of nuts, such as square nuts, round nuts, ring nuts, butterfly nuts, hexagon nuts, and so on. Then the most common nut on the market is the hexagon nut, so why is the hex nut most commonly used? BSP Fittings supplier to share with you:

Hex nuts are the crystallization of the continuous practice of working people in production and life.

1. Hex nuts are made for ease of use. On the machine, the part where the nut is installed is sometimes not sufficiently wide, and the space for the wrench to tighten the nut is also quite small. For hexagonal nuts, you only need to turn the wrench 60 degrees at a time, and you can slowly tighten the nuts, while for square nuts, you need to move 90 degrees each time. In other words, in order to tighten the nut, the hexagonal shape is smaller, but the octagonal nut is easy to slip due to the small contact surface of the wrench and it is rarely used, so the hexagonal nut is the most convenient to use. Look at the wrench again. The handle and the opening of the ordinary wrench can become an angle of 30 degrees. In this way, when the place where the nut is installed is very narrow and the wrench cannot move freely, and the hexagonal nut, as long as the wrench is used to move a nut, Turn the wrench over again and tighten the nut again, so that you can tighten the nut by repeatedly turning it back and forth several times.

2. Hex nuts are made to maximize the use of materials. Because from the strength point of view, large nuts are stronger than small ones. In the past, nuts were generally milled from round materials. The same round rod was used to make a hexagonal nut rather than a square nut. Hex nuts that are tall and made of round rods of the same thickness are much larger than square nuts.

In summary, hexagon nut china is more convenient to use and can increase the use of materials, so it is the most common in the market.

Hex nuts are used in conjunction with bolts and screws to connect and fasten parts. Among them, Type 1 six-purpose nuts are the most widely used. C-level nuts are used on machines, equipment or structures with rough surfaces and low accuracy requirements; A-level and B-level nuts are used for relatively smooth surfaces and high accuracy requirements Machinery, equipment or structure. The thickness M of type 2 hex nut is relatively thick, and it is mostly used in the occasions where assembly and disassembly are often required. The thickness M of the hexagonal thin nut is relatively thin, and it is mostly used in situations where the surface space of the connected parts is limited.
