Clarification on Anchor Type and Variations
This product is a specific variation of the classic hollow wall anchor (often called a “Molly Bolt”), distinguished by its hex head bolt. This design allows for significantly higher installation torque compared to screwdriver-driven versions.
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:
- Cross Semi-Round Head: A standard, low-profile Phillips head bolt.
- Countersunk Flat Head: For a flush finish with the wall surface.
- L-Bolt (Hook Bolt): For creating a direct hanging point.
- Eye Bolt: For applications requiring a closed loop for suspension.
- Eye Hook Bolt: An open hook for easy hanging and removal of items.
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 hexagonal head bolt. The flange has small teeth on its underside designed to bite into the wall surface, preventing the anchor from spinning during installation. When the hex bolt is tightened with a wrench, it draws the threaded part of the sleeve towards the front, causing the slotted body to collapse and expand into a set of “legs” that clamp firmly against the back of the wall.
- Installation Process:
- Drill a hole in the wall to the diameter specified for the anchor size.
- 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.
- Use a wrench or a socket set that matches the hexagonal head to turn the bolt clockwise. The hex head allows you to apply significant torque to ensure the anchor expands fully and sets securely behind the wall.
- Key Feature: Once the anchor is set, the bolt can be completely removed to position your fixture (e.g., a heavy-duty bracket). The anchor body will remain securely expanded in the wall.
- Place your fixture over the anchor and re-insert the bolt, tightening it with the wrench to secure the item.

Key Features
- High-Torque Installation: The hexagonal head is designed to be driven with a wrench or socket, allowing for maximum tightening force and a superior hold.
- Heavy-Duty Load Capacity: Ideal for mounting heavy items, as the high installation torque ensures the anchor is fully and securely set.
- Removable Bolt: The bolt can be removed and re-inserted after the anchor is set, making it exceptionally convenient for mounting heavy or bulky fixtures.
- Durable Construction: Made from high-strength carbon steel with a corrosion-resistant white zinc finish for longevity.
- Anti-Rotation Flange: The toothed flange prevents the anchor body from spinning in the hole during tightening, ensuring a proper and secure set.
Common Applications
This anchor is the premier choice for heavy-duty fastening in hollow walls where maximum strength is required.
- Mounting large flat-screen TV brackets.
- Securing heavy kitchen cabinets, industrial shelving, or workbenches.
- Installing radiators, wall-mounted air conditioning units, or other heavy appliances.
- Anchoring safety equipment, grab bars, or handrails that are subject to high loads.
- Fastening heavy machinery or equipment to hollow block walls in industrial settings.
