eye bolt anchor

The Duojia Eye Bolt series offers a versatile range of fasteners designed to provide a secure attachment point for various applications. These bolts feature a threaded shank and a shaped head, available as a closed loop (O-Type Eye Bolt), an open hook (C-Type Hook Bolt), or an angle hook (L-Type Hook Bolt). Manufactured from durable Carbon Steel or corrosion-resistant Stainless Steel (304), these fasteners are fundamental components in construction, rigging, suspension, and general DIY projects.

Crucial Clarifications on Product Specifications

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

  • Head Types Explained: The specification “Head: O/C/L Bolt” refers to three distinct products:
    • O-Type: A standard Eye Bolt with a fully closed loop. This is used for secure, permanent connections with ropes, cables, or shackles.
    • C-Type: An Open Hook Bolt with a C-shaped hook. This allows for items to be easily hung and removed.
    • L-Type: An L-Hook Bolt or Angle Bolt. This is used for hanging items or as a specific positioning anchor.
  • Grade Inconsistency: The listed grades “4.8/8.2/2” are ambiguous.
    • 4.8 is a standard property class for common carbon steel bolts.
    • “8.2” is not a standard grade and is likely a typo for 8.8, a high-strength carbon steel grade.
    • “2” is not a standard grade designation.
    • Customers should specify their required strength, such as Grade 4.8 for general use carbon steel or the inherent strength of Stainless Steel 304 (A2).
  • Material and Finish: The materials and finishes are distinct:
    • Carbon Steel bolts are typically supplied with a Yellow Zinc Plated finish for moderate corrosion resistance.
    • Stainless Steel (SS304 / A2) bolts are supplied with a Plain (Passivated) finish, as they are naturally corrosion-resistant.
  • Working Load Limit (WLL): A critical safety factor for eye bolts is their Working Load Limit, especially if used for lifting or suspending heavy objects. Standard, bent-wire eye bolts are NOT rated for lifting. Only forged eye bolts with a specified WLL should be used for overhead lifting. Customers must verify the WLL for their specific application.

Detailed Description of Head Types

  • O-Type (Eye Bolt):
    Features a fully closed loop, providing a secure, captive connection point. It is ideal for attaching shackles, turnbuckles, snap hooks, and for threading ropes or cables through. When properly rated (i.e., forged, not just bent), it can be used for light-duty lifting and rigging.
  • C-Type (Open Hook Bolt):
    Features an open, C-shaped hook. Its primary advantage is the ease of hanging and removing items without needing to open a shackle or untie a rope. It is perfect for hanging tools, extension cords, or temporary fixtures. It should not be used for lifting or applications where the load could become dislodged.
  • L-Type (L-Hook Bolt / Angle Bolt):
    Features a 90-degree bend, forming an “L” shape. It is commonly used for hanging items flush against a vertical surface or for specific alignment and anchoring purposes in construction and carpentry. Like the C-Type, it is not intended for overhead lifting.

Key Features

  • Versatile Design: Available in O, C, and L types to suit a wide range of anchoring and hanging needs.
  • Material Options: Choose between economical, zinc-plated Carbon Steel for general use or corrosion-resistant Stainless Steel for outdoor, humid, or food-grade environments.
  • Secure Anchoring: Provides a reliable point for attaching lines, wires, chains, and other hardware.
  • Broad Applications: Suitable for use in wood, concrete (with an anchor), and metal for projects in construction, agriculture, home, and industry.
