توضيح بشأن نوع المرساة وتصميمها

This fastener is a type of hollow wall anchor. Its design features a hollow plastic expansion sleeve with pre-cut slots and an internal thread. When a screw is inserted and tightened, the sleeve is designed to collapse and expand behind the drywall, creating a broad contact area that distributes the load and provides a secure grip.

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

• Grade: The listed strength grades (e.g., 4.8, 8.8, 10.9) are standards for the mechanical properties of steel bolts and are entirely inapplicable to plastic anchors. The holding strength of this anchor is determined by its design, the quality of the plastic, and the integrity of the drywall, not by a steel grade.
• Application: The application listed as “Heavy Industry” is incorrect. As confirmed by the product’s own introductory text, these anchors are for “low to medium load applications” with a typical capacity of up to 15kg. They are not suitable for heavy industrial or structural loads.
• Size: The general “Size” range of M6-M20 is a generic placeholder and is inaccurate for this specific product. The detailed sizing table correctly indicates it is designed for small screws with a diameter of 3mm to 3.5mm.
• Dimensional Table: The column labeled “Recommend Hole Size” with a value of “40” is likely a typographical error and should be interpreted as “Recommended Hole Depth (mm)”, as it logically follows the anchor’s length of 34mm.

آلية المنتج والتركيب

The anchor functions by expanding behind the hollow wall material to create a secure, load-bearing brace.

• Installation Process:
  1. حفر الحفرة Using a 10mm drill bit, drill a hole in the drywall ceiling.
  2. تنظيف الحفرة: Remove any dust and debris from the hole.
  3. أدخل المرساة: Push the plastic expansion anchor into the hole until its collar is flush with the ceiling surface.
  4. Fasten the Object: Place your fixture (e.g., a light fixture base) over the anchor and drive the appropriate screw (3mm to 3.5mm diameter) into the anchor’s core using a Phillips screwdriver.
  5. ضبط المرساة: As the screw tightens, it will pull the back of the anchor, causing the slotted sleeve to expand and grip the inside of the drywall tightly. Do not over-tighten, as this can damage the drywall or the anchor.
