Heavy Duty M4-M12 Nylon Wall Plug Anchor for Concrete and Solid Walls Ribbed Design for Max Grip and Anti-Spin

Description

What Are Wall Plug Anchor?

Wall plug anchor, also known as plastic anchors or wall plugs, are inserts used to enable screw attachment in materials that are porous, brittle, or otherwise unable to support threads . Typically made from soft material like plastic, they are inserted into a drilled hole; as a screw is driven in, the plug expands against the walls of the hole, creating a tight conforming grip .

Materials

• Polyamide (Nylon/PA6) – Most common for standard applications

• Polyethylene (PE) – Corrosion-resistant for light-duty use

• Polypropylene (PP)

Surface Finish

• Unfinished (Plain)

• Color-coded variants (Grey, Yellow, Red, Blue, Green, White) for size identification

Specifications

• Common Sizes: 5mm to 14mm diameter; 25mm to 75mm length .

• Drill Hole Diameter: Matches anchor diameter (e.g., 6mm anchor requires 6mm drill bit) .

• Recommended Screw Diameter: Typically smaller than anchor (e.g., 6mm anchor accepts ø4.5mm screw) .

• Temperature Range: -40°C to +85°C .
