The Yellow Fish-Type Wall Plugs represent a highly reliable plastic expansion tube anchor engineered for secure fastening in hollow walls, plasterboard, and various masonry substrates. Manufactured from premium-grade PE and advanced engineering plastics, these anchors deliver exceptional resistance to aging, corrosion, and extreme temperature fluctuations. When handling these plugs, installers will notice the firm yet adaptable texture of the polymer, which is specifically designed to compress smoothly during insertion and expand aggressively once engaged.
The distinctive biomimetic "fish" or "wing" profile provides a mechanical interlock behind the wall surface. As the screw is driven into the tube, the lateral fins deploy outward, creating a substantial load-bearing footprint that significantly outperforms standard straight-wall plugs. This structural expansion mechanism allows them to bear considerably more weight than conventional anchors, ensuring exceptional pull-out resistance and long-term stability for critical fixtures in demanding construction environments.
The specialized geometry of these fish-type plugs allows them to flare outward and firmly grip the internal surfaces of the cavity. This mechanism creates a highly secure anchor point that resists lateral and outward forces, preventing fixture detachment under sustained loads.
Equipped with pronounced external fins or wings, the plug is structurally restricted from turning when the screw is tightened. These fins bite into the surrounding substrate, ensuring the screw can be properly driven in and the fixing remains absolutely secure without stripping the drill hole.
While exceptionally useful and effective in delicate plasterboard, their versatile expansion profile ensures reliable performance across multiple hollow materials, including particleboard, lightweight partitions, or even some types of solid brickwork, reducing the need to source multiple anchor varieties.
The standardized design facilitates rapid workflow. They are generally easy to insert into a pre-drilled hole, and the smooth internal channel guides the screw accurately, minimizing resistance during the initial drive and significantly lowering labor time across large-scale installation projects.
Fish type plugs come in different standard sizes to accommodate various screw sizes and load requirements. We support comprehensive customization, including non-standard dimensions and specific color-coding based on precise technical drawings to meet unique project specifications.
Compared to some specialized metal anchors, they offer an outstanding balance of holding strength and cost. By optimizing manufacturing efficiency, they provide the reliability of premium fasteners without the associated expense, making them a highly practical choice for many volume applications.
Every batch is manufactured under strict ISO9001 and ISO14001 environmental management systems. With 100% whole-range inspection throughout the production cycle and SGS certification, we guarantee absolute dimensional consistency and performance reliability for every single unit delivered.

Our plastic expansion wall plugs are engineered for versatility, serving as a critical fastening solution widely used in construction and decoration fields. They are specifically designed to handle the unique challenges of hollow and semi-solid substrates, ensuring safety and stability.
Achieving maximum load capacity requires proper installation technique. Follow these standardized steps to ensure a secure and lasting fixture, minimizing material waste and saving valuable on-site labor time:
1. Hardware Selection: Choose drywall screws of appropriate length according to the thickness and hardness of the board. Make sure that the length of the nail is slightly larger than the thickness of the material combined with the plug, and the diameter is moderate, avoiding being too thick (which splits the plug) or too thin (which fails to trigger expansion).
2. Determine the Installation Location: Use a pencil or precision marking tool to mark the exact location on the board to be fixed, and make sure that the spacing of the nails is even to distribute the load effectively.
3. Pre-Drill Small Holes: Use a suitable masonry or wood drill bit to pre-drill small holes at the marked location. The hole diameter should match the unexpanded outer diameter of the plug so that the drywall screws and anchor can be easily inserted with a snug fit.
4. Prepare Tools: Drywall screws are usually installed with a manual screwdriver or a variable-speed electric screwdriver. Make sure the drive bit is perfectly suited for the size and head type of the screw to prevent cam-out.
5. Insert and Fix the Drywall Screw: Push the plastic expansion tube firmly into the pre-drilled small hole. Insert the drywall screw into the plug and fix it in the wall with a screwdriver or electric screwdriver. Pay close attention to control the torque force; listen for the subtle sound of the plastic compressing and stop driving just as it seats firmly to avoid over-tightening and causing the board to crack.
6. Check the Fixing Effect: After the installation is completed, physically check the fixing effect of the drywall screw by applying gentle pressure to ensure that the board or fixture is firmly connected and exhibits no lateral movement.
Watch the demonstration below to see the precise expansion mechanism and structural integrity of our fish-type wall plugs in action during a standard installation procedure.
Understanding the rigorous demands of large-scale procurement, we offer highly flexible packaging configurations designed to optimize storage space and reduce transit costs. Our standard industrial bulk packaging utilizes heavy-duty, moisture-resistant poly bags packed into reinforced corrugated cartons, ensuring the expansion tubes remain pristine and undeformed during long-haul shipping. For clients servicing specialized distribution channels, we provide customizable packaging options including branded blister packs, color-coded sorting boxes, and specific quantity bagging. By maximizing pallet density and streamlining our logistics protocols, we actively help our partners minimize their comprehensive supply chain expenses.
Q1: What sizes are Fish Type Wall Plugs available?
A1: We provide these expansion wall plugs in a comprehensive variety of sizes to match diverse project demands, including 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, and 10 mm diameters. Additionally, we can manufacture custom dimensions according to the specific technical drawing provided by the customer.
Q2: Can different materials be used with these wall plugs?
A2: Yes, their versatile expansion mechanism allows them to be used effectively on multiple substrates. While they excel in hollow spaces like plasterboard, they provide equally secure anchoring in solid concrete, lightweight block, and traditional brick.
Q3: How much can these wall plugs last at the highest load?
A3: The ultimate load-bearing capacity is determined by the specific type of plug used, the integrity of the base material, and the material's specific plug size selected. However, these fish-type wall plugs are structurally designed to withstand medium to heavy static loads, maintaining their grip without degrading over extended periods.
