Welcome to Hefei SENOTECH New Materials Co., Ltd – your trusted partner for high-performance fastening solutions. Since 2020, we have specialized in supplying durable plastic expansion anchors designed for concrete and masonry heavy-duty fixing. Our PA66 nylon ribbed design anchors offer exceptional grip and load distribution, ideal for professional contractors and DIY enthusiasts alike. With an annual export value of US$1-1.5 million, we serve markets across North America, Europe, Asia, and beyond, ensuring factory-direct pricing and fast delivery.
These anchors are engineered to provide reliable performance in solid and hollow base materials, reducing installation time and improving safety. Available in full sizes (from 6mm to 16mm diameter), they accommodate a wide range of screw variants. The unique ribbed body prevents rotation during installation, while the tapered expansion ensures a tight fit. Below, we break down the key features and technical specifications.
Key Features & Benefits
- Material Excellence: Made from PA66 nylon – high strength, corrosion-resistant, lightweight, and non-conductive.
- Ribbed Anti-Rotation Design: The external ribs bite into the substrate, preventing the anchor from spinning during screw installation.
- Heavy-Duty Load Capacity: Suitable for fixing shelves, cabinets, handrails, electrical fixtures, and more.
- Full Size Range: Available from 6 mm to 16 mm diameter, with lengths to match common screw sizes.
- Versatile Application: Perfect for concrete, brick, hollow block, stone, and other masonry surfaces.
- Easy Installation: Simply pre-drill a hole, insert the anchor, and drive the screw – no need for wall plugs in many cases.
- Cost-Effective: Factory-direct supply reduces middleman costs, delivering competitive pricing for bulk orders.
