Known for its specific strength rating, corrosion resistance, and versatility, this bolt has become essential in projects where stability, durability, and safety are paramount. This article provides an in-depth look at the Ige Filetée Zn 5.8 / HDG 5.8 M24 x 210, covering its specifications, applications, material properties, and advantages, so that engineers, builders, and procurement professionals can make informed choices for their projects.
Key Specifications of Ige Filetée Zn 5.8 / HDG 5.8 M24 x 210
Understanding the specifications of the Ige Filetée Zn 5.8 / HDG 5.8 M24 x 210 bolt is essential to selecting the right fastener for the job. Here’s a breakdown of the key specs:
- Size: M24 x 210 – This indicates a metric size with a diameter of 24mm and a length of 210mm.
- Strength Grade 5.8: The “5.8” rating refers to its tensile strength, with the 5 indicating the ultimate tensile strength of 500 MPa, and the 8 representing 80% of its tensile strength in terms of yield.
- Zn (Zinc) and HDG (Hot-Dip Galvanization) Coating: Zn and HDG refer to zinc and hot-dip galvanization, respectively, which both enhance corrosion resistance and make the bolt suitable for outdoor and industrial applications.
What Does Strength Grade 5.8 Mean?
The 5.8 grade classification is a standardized way of describing the bolt’s mechanical properties. In this case, “5” and “8” provide two essential pieces of information:
- Ultimate Tensile Strength (UTS): The “5” signifies that this bolt has a UTS of 500 MPa, which is the maximum stress the bolt can withstand before it breaks.
- Yield Strength: The “.8” refers to 80% of the UTS, giving a yield strength of 400 MPa. This is the stress level at which the bolt will begin to deform permanently.
This classification is essential for applications where the load-carrying capacity of a bolt must meet specific safety standards.
Zinc Coating vs. Hot-Dip Galvanization (HDG)
Zinc Coating
The Zn designation indicates a zinc-coated bolt, which offers a layer of corrosion resistance. This coating helps protect the bolt from rust, making it more suitable for environments where exposure to moisture is a concern. Zinc-coated bolts are commonly used in construction, especially for indoor or mildly corrosive outdoor applications.
Hot-Dip Galvanization (HDG)
The HDG or hot-dip galvanized process provides a thicker, more durable layer of zinc compared to traditional zinc plating. Hot-dip galvanization is a process in which the bolt is submerged in molten zinc, creating a more robust layer that adheres closely to the steel. This technique makes HDG bolts ideal for outdoor and industrial applications where moisture, chemicals, and temperature fluctuations can wear down other types of coatings.
Dimensions: M24 x 210
The M24 x 210 designation refers to the bolt’s metric sizing, where “M24” indicates a 24mm diameter and “210” refers to its length of 210mm. Here’s what each measurement implies:
- Diameter (M24): The diameter impacts the bolt’s strength and suitability for heavy-duty applications, as a 24mm diameter offers significant load-bearing capacity.
- Length (210mm): The length ensures versatility for various applications, from securing steel beams to industrial machinery installation.
Material Composition of Ige Filetée Zn 5.8 / HDG 5.8 M24 x 210 Bolts
To ensure strength and longevity, the Ige Filetée Zn 5.8 / HDG 5.8 M24 x 210 bolt is made from medium-carbon steel. This type of steel contains a balanced amount of carbon to achieve durability and tensile strength, while still maintaining some flexibility. Combined with the zinc or HDG coating, this steel composition makes it resistant to corrosion, oxidation, and physical wear.
