Zinc Plated eye bolt

Zinc Plated eye bolt

The Duojia Zinc Plated Eye Bolt is a robust and economical fastener designed to provide a secure anchoring point for a wide variety of applications. This product consists of a threaded shank with a closed loop, or “eye,” at one end. It is manufactured from durable Carbon Steel and then coated with a layer of zinc for corrosion resistance. The most common finish mentioned is Yellow Zinc Plated, which offers good protection against moisture and rust in indoor or mild outdoor environments.

Crucial Clarifications on Product Specifications

The product page provides general information covering multiple product variations. The following clarifications are specific to the Zinc Plated Eye Bolt:

  • Material and Finish: The term “Zinc Plated” refers to the finish, not the base material. These bolts are made from Carbon Steel and then plated with zinc. This is distinct from the Stainless Steel option, which does not require plating.
  • Grade Ambiguity: The listed grades “4.8/8.2/2” require clarification:
    • Grade 4.8: This is a standard property class for common, low-strength carbon steel bolts. It is suitable for most general-purpose applications where high tensile strength is not required.
    • Grade 8.2: This is not a standard ISO grade. It is most likely a typographical error for Grade 8.8, which is a common high-strength, heat-treated carbon steel grade. Customers requiring higher strength should specify Grade 8.8.
    • Grade 2: This is an imperial (SAE) grade designation and is generally not used for metric fasteners. It is roughly equivalent to Grade 4.8.
  • Lifting Safety: Standard, bent-wire eye bolts are NOT rated for overhead lifting. Their purpose is for anchoring, guiding, and positioning. For any lifting or load-bearing suspension, you must use a forged, shouldered machinery eye bolt with a specified Working Load Limit (WLL). You must confirm the WLL with the manufacturer before using any eye bolt for a critical load.

Key Features

  • Good Corrosion Resistance: The zinc plating provides a protective barrier against moisture, preventing the carbon steel from rusting in mild conditions.
  • Cost-Effective Solution: Carbon steel is more economical than stainless steel, making these bolts an excellent choice for budget-conscious projects where extreme corrosion resistance is not needed.
  • Secure Connection Point: The closed-loop “O-Type” head ensures that ropes, cables, or hooks will not slip off, providing a secure and reliable attachment point.
  • Versatile Installation: Can be installed into wood, or into concrete and masonry with the use of a suitable anchor.

Typical Applications

  • Creating tie-down points on trailers, workbenches, or in workshops.
  • Guiding garden wire, clotheslines, or light-duty cables.
  • Hanging lightweight signage, decorations, or tools.
  • Use in DIY furniture and construction projects for bracing or anchoring.
  • Shop and garage organization.
