Hex Bolt Carbon Steel Grade 8.8 M10 1/2'' ASTM A193 A194 Black Oxide Coating Heavy-Duty Construction
Product Description:
This hex bolt is manufactured from high-strength carbon steel, rated at grade 8.8, which is designed to withstand heavy loads and extreme pressure in industrial and construction applications. The M10 size with a 1/2-inch thread provides a robust fastening solution for various mechanical and structural connections. The black oxide coating not only enhances the bolt’s appearance but also provides increased resistance to corrosion, making it ideal for use in environments exposed to moisture or chemicals. The bolt adheres to the ASTM A193 and A194 standards, ensuring it meets international strength and quality requirements. The black oxide finish also helps to reduce friction and improve wear resistance, making it a preferred choice in heavy-duty construction projects, machinery assembly, and automotive industries.
Applications
Black oxidation treatment is a common means of chemical surface treatment, the principle is to produce a layer of oxide film on the surface of the metal, in order to isolate the air, to achieve the purpose of rust prevention.Appearance requirements are not high when you can use the blackening treatment, the surface of steel parts blackening treatment, there are also called blue.Black oxidation treatment, because it can eliminate reflections, refers to a surface coating treatment commonly used for military knives
In order to improve the rust resistance of steel parts, a strong oxidising agent is used to oxidise the surface of the steel parts into a dense, smooth layer of iron tetraoxide.This thin layer of iron tetraoxide effectively protects the interior of the steel part from oxidation.At high temperature (about 550℃) the oxidised iron tetraoxide is sky blue, so it is called bluing treatment.The iron tetraoxide formed at low temperature (about 350°C) is dark black, so it is called blackening treatment.In the manufacture of weapons, commonly used is the blue treatment; in industrial production, commonly used is the blackening treatment.
