An overview of the characteristics of threaded rods that you need to know

Threaded rods, also known as threaded rods, is a widely used concept in construction or mechanical engineering. However, what are threaded rods used for, and what are the characteristics of threaded rods that not everyone understands? Therefore, the following article Ty Viet will help you have the most overview about threaded rods.

Features of threaded rods

Threaded rods are considered an important detail in the assembly process. It is a straight rod whose length ranges from 1-3m. threaded rods are used to connect auxiliary structures (high-rise water systems, fire fighting systems, cable systems, etc.) to the stable structures of the building or to fix the concrete formwork.

The surface of threaded rods is smooth and even spirals called threads, which help it do the fast and easy task of fastening with accessories, creating strong bonds that are difficult to break.

Currently, on the market there are many types of threaded rods that differ in size, shape, material and quality. Depending on your needs, finances and actual construction conditions, you can then choose the appropriate threaded rods products, ensuring the safest construction.

Threaded rods classification

Normally, people will classify threaded rods depending on the characteristics of threaded rods as follows:
Classification based on durability

Since threaded rods are often used mainly for pulling parts, durability is paramount. Users need to calculate how much force and cross-section the threaded rods can withstand. From there, make calculations and choose accordingly.

Common types of durable grade threaded rods:

– threaded rods grade 4.8: are threaded rods of normal strength and have a minimum tensile strength of 4000 g/cm2.
– threaded rods of durability grade 5.6: are threaded rods of medium strength and have a minimum tensile strength of 5000 kg/cm2.
– threaded rods grade 8.8: are threaded rods with high durability and a large bearing capacity of at least 8000 kg/cm2. Classification of threaded rods by coating grade

Threaded rods often have a coating on the outside to ensure aesthetics when assembled with products and enhance resistance to weather conditions. Based on this coating, people can be divided into the following categories

– Electroplated threaded rods: this is the most popular type of threaded rods, because of its high durability in dry environments and its affordable price.
– hot-dip galvanized threaded rods: this type of threaded rods has high carrying capacity in outdoor environmental conditions. With thick plating and large diameter threaded rods.

Sort by size

+ threaded rods M6/d6 (phi 6): use workpieces with diameters from 4.6mm-5mm.
+ threaded rods M8/d8 (phi 8): use workpieces with diameters from 6.8mm – 7mm.
+ threaded rods M10/d10 (phi 10): use workpieces with diameters from 8.6mm-8.8mm.
+ threaded rods M12/d12 (non 12): use workpieces with diameters from 10.5 -10.8mm.

Besides, there are many other diameters such as: M16/M18/M20,…M56.
