Clarification on Anchor Type and Design

This type of fastener is commonly known as a wall plug, rawl plug, or screw anchor. It is a small, hollow sleeve, typically made of nylon or other plastics, featuring external ribs or “fins.” These fins are designed to prevent the anchor from spinning in the hole during screw installation and to increase its frictional grip against the base material. The anchor is split along its length, allowing it to expand as a screw is driven into it.

Important Clarification on Product Parameters:
It is essential to note that the product parameters provided on the source page contain significant inaccuracies that are inconsistent with the nature of a plastic wall anchor.

• Grade: The listed strength grades (e.g., 4.8, 8.8, 10.9) are standards for steel bolts and are not applicable to plastic anchors. The strength of a plastic anchor is determined by its material (nylon), its specific design, and the integrity of the base material it is installed in, not by a steel grade.
• Application: The application listed as “Heavy Industry” is incorrect. Nylon wall plugs are intended for light to medium-duty applications, such as hanging pictures, shelves, curtain rods, and light fixtures. They are not suitable for heavy industrial or structural loads.
• Size: The “Size” range of M6-M20 most likely refers to the metric screw size the plug is designed to accept, not a metric thread size of the plug itself.

Product Mechanism and Installation

The anchor works on the principle of friction and expansion. When a screw is driven into the hollow center of the plug, it forces the split sections of the anchor to expand outwards. This expansion presses the anchor’s ribbed body firmly against the inner walls of the drilled hole, creating a secure frictional hold that resists pull-out forces.

• Installation Process:
  1. Drill the Hole: Using a drill bit that matches the outer diameter of the plastic anchor plug, drill a hole into the wall or base material. The depth should be slightly longer than the length of the plug.
  2. Clean the Hole: For masonry applications, clear any dust and debris from the hole to ensure a snug fit.
  3. Insert the Plug: Push the anchor plug into the hole until its collar is flush with the surface of the wall. If needed, tap it gently with a hammer.
  4. Fasten the Object: Place your fixture (e.g., a bracket) over the inserted plug, align the mounting hole, and drive the appropriate-sized screw through the fixture and into the center of the plug. As the screw tightens, the plug will expand and secure itself. Avoid over-tightening to prevent damage to the plug or the wall.
