spring anchor with hook and washer

spring anchor with hook and washer

The Duojia “Spring Toggle Open Type Fixing With Washer” is a premium hollow-wall anchor designed for maximum durability and reliability, especially in environments where corrosion is a concern. This fastener is manufactured entirely from high-grade Stainless Steel and combines three key elements: the secure holding power of a spring-loaded toggle, the convenience of an open hook head, and the added stability of an included stainless steel washer. It is the ideal solution for hanging items in hollow materials like drywall, plasterboard, and hollow block in demanding locations such as kitchens, bathrooms, outdoor areas, and marine environments.

Clarification on Product Design and Specifications

This product has several distinct features that set it apart from standard toggle bolts.

  • Material: Stainless Steel (SS): This is the anchor’s primary feature. The use of stainless steel (such as A2/304 or A4/316 grades) provides superior resistance to rust and corrosion compared to zinc-plated carbon steel. This makes it essential for use in humid or wet locations (bathrooms, kitchens, outdoors) or where exposure to chemicals or salt spray is possible.
  • Head Style: Open Hook: The anchor is fitted with an open hook screw, allowing for the direct and immediate hanging of items with chains, wires, or loops. This eliminates the need for any secondary hardware.
  • Included Component: SS Washer: The anchor comes with a matching stainless steel washer. When installed, the washer sits between the base of the hook and the wall surface. Its purpose is twofold: to distribute the clamping force over a wider area to prevent damage or crushing of the wall material (especially soft plasterboard), and to provide a more stable, finished look.
  • Size Range (M6-M20): The listed size range is extremely broad and serves different applications.
    • Light to Medium Duty (e.g., M6, M8): These sizes are perfect for residential and commercial use in drywall, hanging fixtures, towel racks, or decor in bathrooms and kitchens.
    • Heavy Duty (e.g., M10-M20): These larger, industrial-grade sizes are designed for anchoring into more substantial hollow materials like hollow concrete block (CMU) and are suitable for suspending heavier equipment, signage, or fixtures in commercial or industrial settings.

Product Mechanism and Installation

The anchor provides a secure hold by bracing its toggle wings against the back of the hollow wall or ceiling.

  • Mechanism: The anchor consists of a stainless steel open hook screw, a matching stainless steel washer, and a threaded, spring-loaded stainless steel toggle wing assembly.
  • Installation Process:
    1. Select the appropriate size anchor for your load and wall material. Drill a hole in the wall large enough for the folded toggle wings to pass through.
    2. Unscrew the toggle wings from the hook screw.
    3. Slide the stainless steel washer onto the hook screw. If you are hanging a fixture with a mounting hole, pass the hook screw through the fixture’s hole first, then add the washer.
    4. Thread the toggle wings back onto the end of the hook screw by a few turns.
    5. Fold the wings flat and push them through the drilled hole. You will feel them spring open inside the wall cavity.
    6. Pull back on the hook to seat the wings firmly against the inside surface of the wall.
    7. While maintaining tension, tighten the hook screw by hand or with pliers until the washer is snug against the wall surface. This clamps the assembly securely.
