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 line:

• Finish Conflict (Black Oxide vs. Zinc Plated): The product title and finish field clearly state “Black Oxide Coating”, while the surface treatment field lists “zinc plated”. Black Oxide is a chemical conversion coating that provides mild corrosion resistance and an aesthetic black finish. Zinc plating is a metallic coating for more robust rust prevention. Given the product’s title and description, Black Oxide is the primary intended finish. Zinc plating may be available as an alternative, but the featured product is black oxide.
• Grade Inconsistency: The “Grade” field lists both carbon steel property classes (4.8, 8.8, 10.9, 12.9) and stainless steel grades (A2-70, A4-70). Since the material is explicitly listed as “Carbon Steel”, only the carbon steel property classes are applicable to this product. The stainless steel grades are incorrect for this item.
• Lifting Safety & WLL: The term “Lifting Eye Bolt” implies it is suitable for hoisting loads. While high-strength grades (like 8.8, 10.9, 12.9) are designed for this, the DIN 444 standard itself is a dimensional standard, not a lifting performance standard. The actual safe Working Load Limit (WLL) depends on the material grade, size, and how the load is applied. Users must confirm the specific WLL from the manufacturer before using these bolts for any overhead lifting.

Product Parameters (Corrected and Clarified)

Key Features

• High-Strength for Lifting: Available in heat-treated, high-tensile grades (8.8, 10.9, 12.9) suitable for demanding lifting and rigging operations.
• Conforms to DIN 444 Standard: Ensures dimensional consistency for use in jigs, fixtures, and machinery where precise fitment is required.
• Durable Black Oxide Finish: Provides a protective surface that prevents galling, offers mild corrosion resistance, and is ideal for indoor industrial environments.
• Versatile Connection Point: The elongated eye is designed to accept hooks, pins, shackles, and other rigging hardware.
• Forged Construction: High-strength lifting eye bolts are typically forged (not just bent) for superior strength and load-bearing integrity.

Typical Applications

• Lifting and Hoisting: Attaching to machinery or heavy components to provide a secure point for lifting with cranes or hoists.
• Jigs and Fixtures: Used as a pivot pin or clamping bolt in manufacturing and assembly jigs.
• Securing and Tie-Downs: Creating robust anchor points for securing heavy loads during transport or in industrial settings.
• Tensioning Systems: Used in conjunction with turnbuckles and other hardware to tension cables or rods.
