Welcome to Hefei SENOTECH New Materials Co., Ltd – your trusted partner for high-performance fastening solutions. As a dynamic trading company established in 2020, we have rapidly expanded our global footprint, exporting over US$1 million to US$1.5 million annually to markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. Our Expansion Plugs for Masonry with PE Material Anti-rotation Design Full Sizes Heavy Duty represent the perfect blend of reliability, durability, and versatility. Crafted from premium polyethylene (PE) and featuring an innovative anti-rotation ribbed design, these plugs deliver exceptional holding power in a wide range of masonry substrates. Whether you're securing fixtures in concrete walls, brick facades, or stone surfaces, our full-size range ensures you will find the exact anchor for your project. We take pride in offering products that simplify installation while maximizing load-bearing performance – a direct result of our commitment to quality and customer satisfaction.
Our expansion plugs are engineered to tackle the toughest masonry applications. The PE material provides excellent resistance to moisture, chemicals, and UV degradation, making them suitable for both indoor and outdoor use. The anti-rotation design consists of strategically placed ribs that grip the sides of the drilled hole, preventing the plug from spinning during screw insertion – a common frustration with standard plastic anchors. This feature ensures a secure, vibration-resistant fix every time. Available in full sizes from 6mm to 20mm diameter and lengths ranging from 30mm to 100mm, our heavy-duty plugs can accommodate screws of various gauges. Designed for use with wood, chipboard, or self-tapping screws, these plugs are ideal for mounting shelves, cabinets, TV brackets, handrails, curtain rods, and heavy equipment. Below is a detailed specification table for your reference:
| Size (Diameter × Length) | 6×30mm, 8×40mm, 10×50mm, 12×60mm, 14×70mm, 16×80mm, 20×100mm |
| Drill Bit Diameter | Same as plug diameter (e.g., 6mm plug requires 6mm drill bit) |
| Embedment Depth | Approximately 80% of plug length |
| Recommended Screw Diameter | 4.5mm to 5.5mm for 6mm plug; 5.5mm to 7mm for 8mm plug; 7mm to 9mm for 10mm plug; 9mm to 12mm for 12mm+ plugs |
| Max Load Capacity (in concrete) | Up to 20kg (6mm), 30kg (8mm), 40kg (10mm), 50kg (12mm+) |
| Material | High-density polyethylene (HDPE) – UV and chemical resistant |
| Color Options | White, Gray, or custom colors upon request |
Beyond the technical specifications, our expansion plugs offer several distinct advantages for professionals and DIY enthusiasts alike. The anti-rotation ribs not only prevent spinning but also increase the plug's grip against the hole wall, enhancing pull-out resistance. This is particularly important in softer masonry materials like aerated concrete or lightweight blocks, where standard smooth plugs might fail. The PE material is non-corrosive, eliminating the risk of rust stains on finished surfaces – a key benefit for outdoor installations. Additionally, the plugs are designed for easy installation: simply drill a hole of the same diameter, insert the plug flush with the surface, and drive in the screw. The plug expands evenly, distributing the load over a larger area, which reduces the risk of cracking the masonry. For heavy-duty applications, we recommend using our plugs with appropriate screws (not included) to achieve optimal performance. Our full-size range ensures that you can always match the plug to the screw size and the substrate thickness, making these anchors a versatile choice for any project.
To further illustrate the benefits, here are some key points summarized in a bullet list:
- Anti-rotation ribbed design: Eliminates plug spinning, ensures quick and frustration-free installation.
- Heavy-duty load capacity: Suitable for securing medium to heavy fixtures such as shelves, cabinets, and TV mounts.
- Full size availability: From 6mm to 20mm diameter, covering all common screw sizes and masonry applications.
- PE material advantages: Resistant to moisture, chemicals, and UV; no rust or corrosion; lightweight and durable.
- Wide application range: Works in concrete, brick, block, stone, and even some hollow materials with proper screw selection.
- Customizable options: Color, packaging, and special sizes available upon request.
- Cost-effective solution: High performance at a competitive price point, backed by our reliable supply chain.

Frequently Asked Questions
Q1: What is the main advantage of the anti-rotation design?
A1: The anti-rotation ribs prevent the plug from spinning inside the hole when you drive in the screw. This ensures a secure grip, reduces installation time, and improves the overall holding strength, especially in softer masonry materials.
Q2: Can these expansion plugs be used in hollow walls or drywall?
A2: While designed primarily for solid masonry (concrete, brick, block), they can also be used in hollow materials if the plug is long enough to anchor into the solid back layer. However, for hollow walls, we recommend using specialized hollow wall anchors for optimal performance.
Q3: What screw types are compatible with these plugs?
A3: These plugs work well with wood screws, chipboard screws, and self-tapping screws. The screw diameter should match the recommended range for each plug size (see specification table). For best results, use screws with a sharp point and a thread that complements the plug's expansion mechanism.
Q4: Are these plugs suitable for outdoor use?
A4: Yes, the PE material is UV-resistant and does not rust or corrode, making them ideal for outdoor applications such as mounting fences, garden lights, or outdoor furniture. However, ensure that the screws used are also corrosion-resistant (e.g., stainless steel) for a long-lasting installation.
Q5: How do I select the correct size plug for my project?
A5: Choose a plug diameter that matches the drill bit size (e.g., 8mm plug = 8mm drill). The length should be at least 2/3 of the screw's embedment depth. For heavy loads, use a larger diameter plug. Refer to the load capacity table and consult with our technical support for specific applications.
Q6: Can I reuse these plugs after removing the screw?
A6: Reusability depends on the condition of the plug. If the expansion ribs are not damaged and the plug remains intact, you may be able to reuse it. However, for safety and optimal holding power, we recommend using a new plug for each installation, especially when dealing with heavy loads.
Q7: Do you offer custom sizes or colors?
A7: Yes, we can customize plug sizes, colors, and packaging based on your requirements. Minimum order quantities may apply. Please contact our sales team to discuss your specific needs.
Q8: What is the typical lead time for orders?
A8: For standard sizes and colors, lead time is usually 7–15 days after order confirmation. For custom orders, lead time may be 20–30 days depending on the complexity. We work diligently to meet your deadlines.
