Galvanized hex bolt is a metal accessory, also known as hex screw, hex bolt or hex bolt. It is a common fastener widely used in various fields. The surface treatment method for galvanized hexagonal bolts includes galvanizing, which is a corrosion-resistant treatment method that covers the bolt surface with a zinc layer to prevent corrosion and oxidation of the bolt. The methods of galvanizing include hot-dip galvanizing and electroplating galvanizing, among which hot-dip galvanizing is widely used due to its better corrosion resistance. This processing method not only improves the corrosion resistance of the bolts, but also extends their service life.
The grade and performance of galvanized hexagonal bolts mainly depend on their material and application environment. For example, 4.8 grade galvanized hexagon bolts are a common specification, where the number represents the tensile strength of the bolt, and "grade" refers to its hardness level after heat treatment. This type of bolt is typically used in applications that require high strength and corrosion resistance.
1、 Overview of galvanized hexagonal material
Galvanized hexagonal bolt is a compact, high-strength, and high-precision hexagonal bolt. Carbon structural steel or alloy structural steel is generally used as the substrate, and after galvanizing treatment, galvanized hexagonal bolts are formed. Common substrates include Q195, Q235, 20MnTiB, 40Cr, etc.
Galvanizing treatment is the process of immersing bolts in a molten zinc aqueous solution and conducting electrochemical reactions using electricity to precipitate zinc ions on the surface of the bolt, forming a layer of zinc iron alloy. This treatment method can effectively improve the corrosion resistance and durability of the bolt.
2、 Application Fields of Galvanized Hexagon
Galvanized hexagonal bolts are widely used in industrial production and construction fields. Galvanized hexagonal bolts are commonly used in mechanical equipment manufacturing to connect steel components, bearings, and machine tools. In the field of construction, galvanized hexagonal bolts are mainly used to connect steel structures, bridges, and highway guardrails.
Due to its high anti-corrosion, wear resistance, and tensile strength, as well as long service life, galvanized hexagonal bolts have been favored by engineers and builders. Meanwhile, galvanized hexagonal bolts can also be customized in different specifications and sizes to meet the needs of different engineering and construction projects.
The standards for galvanized hexagonal bolts include DIN, ANSI, BS, and GB, which cover aspects such as bolt diameter, length, thread type, and mechanical properties. Specifically:
The diameter range is from 5mm to 20mm, or 1/4 "to 3/4".
The length can range from 8mm to 200mm, or from 5/16 "to 8".
Threads can be in metric, imperial, and different pitch sizes, such as coarse and fine threads.
Mechanical performance levels include 4.8, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, etc.
Surface treatment can include natural color, galvanizing, blackening, nickel plating, etc.

Casters, also known as universal wheels, have a structure that allows for 360 degree horizontal rotation under dynamic or static loads. This type of wheel is usually used in conjunction with fixed casters, which do not have a rotating structure and cannot rotate horizontally but can only rotate vertically. There are various materials for casters, including PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, etc. According to their load-bearing capacity, they can also be divided into micro casters, light casters, medium casters, heavy casters, and ultra heavy casters.
Flange nut, also known as washer nut, serrated nut, hexagonal flange nut, flange nut, etc. Mostly used for pipeline connections or workpieces that require increasing nut contact surfaces.
