Hollow Wall Anchor Hook Bolt

Hollow Wall Anchor Hook Bolt

The Duojia Hollow Wall Anchor with an integrated Eye Hook Bolt is a specialized fastener designed to create a convenient and reliable hanging point on hollow surfaces like drywall, plasterboard, and hollow-core doors. This all-in-one solution combines the strength of a hollow wall anchor with the utility of an open hook, making it perfect for hanging various decorative and functional items. Manufactured from high-grade carbon steel and finished with a protective White Zinc Plating, this anchor offers excellent durability and corrosion resistance for indoor use.

Clarification on Anchor Type and Variations

This product is a specific variation of the classic hollow wall anchor (often referred to as a “Molly Bolt”). It features a permanent, open-ended hook, which is distinct from the “Eye Bolt” version that has a closed loop. The open hook design is ideal for applications where items need to be easily hung and removed.

As indicated by the “Related Products” section on the webpage, the same expanding anchor body is also available from the manufacturer with different bolt types to suit various needs:

  • Eye Bolt: A closed loop for secure, permanent suspension of chains or wires.
  • L-Bolt (Hook Bolt): A right-angle hook for direct hanging.
  • Hex Head Bolt: For high-torque installation with a wrench.
  • Cross Head (Phillips) Bolt: For standard screwdriver installation.

Product Mechanism and Installation

This anchor utilizes a proven expansion mechanism to create a secure hold by clamping onto the back of the hollow wall material.

  • Mechanism: The anchor consists of a cylindrical, slotted sleeve with an integrated flange and a pre-inserted open eye hook bolt. The flange is equipped with small teeth on its underside that are designed to bite into the wall surface, preventing the anchor from spinning during installation. When the eye hook is turned, it pulls the threaded section of the sleeve forward, causing the slotted body to collapse and expand into a set of “legs” that clamp firmly against the back of the wall.
  • Installation Process:
    1. Drill a hole in the wall to the diameter specified for the anchor size.
    2. Gently tap the entire anchor assembly into the hole until the flange is flush with the wall surface. The anti-rotation teeth will grip the wall.
    3. Begin tightening the eye hook by turning it clockwise. This can be done by hand initially.
    4. To apply sufficient torque to set the anchor, insert a screwdriver or a similar rod through the hook to use as a lever. Continue turning until you feel firm resistance, which indicates the anchor has fully expanded and is securely set behind the wall.
    5. The eye hook is now a permanent, secure hanging point ready for use.
