CBIES AUTOMOTIVE|Why Are The Most Commonly Used Nuts Are Hex Nuts
Hexagonal nuts are the most commonly used. Anyone who is familiar with nuts knows that there are many types of nuts. The anti-loosening nut originated from foreign countries. It is permanently attached to the thread with special engineering plastics. During the tightening process of the internal and external threads, the engineering plastics are squeezed to generate a strong reaction force, which greatly increases the gap between the internal and external threads. Friction, which provides absolute resistance to vibration. Such as square nuts, round nuts, ring nuts, wing nuts, hexagonal nuts, etc. Then the most common one on the market is the hexagonal nut, so why is the hexagonal nut the most commonly used?
A. For ease of use, the nut is hexagonal. On the machine, the parts for installing the nut are sometimes not abundant enough, and the space for the nut wrench is also very narrow. A 60-degree pull on the wrench slowly tightens the hex nut, while a 90-degree pull on the quad nut requires one pull. That is to say, hex nuts are smaller for tightening the nuts, but octagon nuts are the most convenient to use because the contact surface between the wrench and them is small, easy to slide, and are usually rarely used. If you look at the wrench, the handle of the normal wrench and the wrench can be at an angle of 30 degrees so that when the nut is installed in a narrow place, the wrench cannot move freely, and the hexagonal nut, as long as the wrench is turned with the nut, it will be fine. Flip the wrench again and pull on the nut again and again so that you can tighten the nut by turning it back and forth a few times.
B. Bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and have been heat-treated (quenched and tempered). They are commonly called high-strength bolts, and the rest are commonly called ordinary bolts. The bolt performance grade label consists of two parts of numbers, which respectively represent the nominal tensile strength value and yield strength ratio of the bolt material. Because in terms of strength, large nuts are stronger than small nuts, and in the past, nuts were generally ground from round materials. The same round rod is more efficient to use to make a hexagonal nut than a square nut. Hex nuts made from round rods of the same thickness are much larger than square nuts. To sum up, the hexagonal nut is more convenient to use and has a higher material utilization rate. It is the most common type of nut on the market. Define the hex nut
As a manufacturer of auto parts for the automotive industry, in terms of stainless steel nut fasteners. CBIES Automobile Company is committed to creating more energy-saving, safe, and lightweight products. The surface of the product is treated with zinc-nickel alloy, and the neutral salt test should reach 720h. Surface burrs are removed and sharp edges are chamfered. The surface of the crystal should be smooth and clean without damage, and the thread profile should be complete, smooth, and free of defects and rust.
