How to Choose Fasteners such as Nuts and Bolts to be more Durable?
February 14,2022
Nuts, bolts, studs, and other fasteners are an important guarantee for the production of manufacturing enterprises. However, there are many kinds of fasteners on the market and their quality is uneven. If you don't pay attention a little, you will buy unqualified fasteners, resulting in loose connections, rust of fasteners, and other problems.
So, what aspects should you start from when selecting fasteners? Don't worry, this blog can help you.
⭕Select the right material and strength
In the fastening and connection work, it is common for fasteners to break. On the one hand, it may be because the material type of fasteners is not selected correctly, on the other hand, it may be because the strength of fasteners is not selected properly.
The fasteners on the market include carbon steel, stainless steel, stainless iron, copper, aluminum, and other materials. Among them, the hardness of carbon steel, stainless steel, and stainless iron will be higher than that of copper and aluminum. Therefore, if it is used to connect parts with large thickness, high hardness, and strong structure, it is necessary to choose fasteners of carbon steel, stainless steel, and stainless iron as far as possible. In this way, the fasteners will not break due to the weight of the connected parts.
At the same time, when selecting fasteners, you also need to pay attention to their strength grade. For example, carbon steel screws have multiple grades such as 4.8, 5.8, 6.8, 8.8, and 10.9. The higher the strength grade, the higher the hardness of fasteners, and the less likely they will break.
⭕See the surface treatment of fasteners
In the market, fasteners such as rivet nuts are mostly made of iron. To prevent iron fasteners from rusting, many manufacturers will zinc, copper, nickel, chromium, silver, and gold on the surface of the iron.
To avoid these coated metals falling off easily during use, resulting in the rust of fasteners when selecting fasteners, it is necessary to focus on the level of the fastener coating process. Generally, if sharp objects are used, the coating is not easy to fall off, and the fasteners with large coating thickness have stronger and more lasting oxidation resistance.
⭕Look at the threads of fasteners
The most likely reason for the looseness of fasteners is that the quality of fasteners is unqualified, especially since the thread of fasteners is not clear enough and the tensile strength is not large enough. Therefore, thread fracture, slips, and other phenomena will occur. Therefore, when selecting fasteners, especially those with internal or external threads, we must choose fasteners with clear threads and high thread tensile strength.
The above is our sharing about selecting fasteners. Do you understand? If you just need high-quality fasteners, you might as well go to AKF FASTENERS to buy them. There are Four Prong Nuts, Heavy Square Nut, Collared Hex Nuts, studs, bolts, and other fasteners made of stainless steel, carbon steel, copper, and other materials.
