Crucial Clarifications on Product Specifications

The product page contains several conflicting or generic data points. The following clarifications provide a precise and accurate understanding of this specific product:

• Finish (HDG vs. Zinc Plated): The product title and “Surface treatment” field correctly identify the finish as “hot-dip galvanized”. The “Finish” field’s listing of “Zinc Plated” is a generic term. Hot-Dip Galvanizing is a specific, more robust process than standard electro-zinc plating, resulting in a much thicker and more protective coating.
• Material (Carbon Steel vs. Stainless Steel): The “Material” field lists both “Stainless Steel” and “Carbon Steel”. The hot-dip galvanizing process is applied to الفولاذ الكربوني to protect it from corrosion. Stainless steel is inherently corrosion-resistant and is not galvanized. Therefore, for this specific HDG product, the material is الفولاذ الكربوني.
• Grade Inconsistency: The “Grade” field lists both carbon steel classes (4.8, 8.8, 10.9, 12.9) and stainless steel grades (A2-70, A4-80). As this is a carbon steel product, only the carbon steel property classes are applicable.
• Thread Fit: The thick coating of HDG requires special consideration for mating parts. The corresponding nut must have its threads tapped oversize to accommodate the added thickness of the zinc on the bolt’s threads. Standard nuts will not fit on an HDG bolt.
• Lifting Safety: While often used in heavy industry and available in high-strength grades (e.g., 8.8), the DIN 444 standard is dimensional, not a lifting performance standard. The Working Load Limit (WLL) must be confirmed with the manufacturer for the specific size and grade before using these bolts for any overhead lifting or critical load-bearing applications.

Product Parameters (Corrected and Clarified)

الميزات الرئيسية

• مقاومة فائقة للتآكل: The thick HDG coating provides exceptional, long-lasting protection against rust, making it perfect for outdoor, coastal, and high-moisture environments.
• Ideal for Outdoor Use: Specifically designed to withstand the elements in applications like construction scaffolding, agricultural machinery, and telecommunication towers.
• High-Strength Options: Available in high-tensile carbon steel grades (8.8, 10.9, 12.9) for reliable load-bearing and demanding industrial use.
• Flexible Connection: The “Live Bolt” design allows for pivoting or rotational connections when used with a pin or clevis.
• Standardized Dimensions: Manufactured to DIN 444 specifications for consistent and predictable fitment in jigs, fixtures, and machinery.

Typical Applications

• Construction: Securing scaffolding, bracing, and anchoring structural elements exposed to weather.
• Agriculture: Linkages on tractors and other farm equipment that require a robust, pivoting connection.
• Utilities: Mounting hardware on utility poles and communication towers.
• Marine: Used in docks and other near-water structures where high corrosion resistance is essential.
• Industrial: Creating heavy-duty, adjustable anchor points in manufacturing plants.
