Introducing our wholesale price anti-rotation expansion plugs – engineered to provide reliable, high-strength anchoring in concrete. Manufactured from high-quality PE (polyethylene) material, these plugs offer excellent corrosion resistance and long-term durability. At Hefei SENOTECH New Materials Co., Ltd, we specialize in supplying cost-effective fastening solutions to global markets, ensuring that every batch meets strict quality control standards. Our full-size range and anti-rotation design make them ideal for heavy-duty applications where safety and stability are paramount.
Key Features & Benefits
Anti-rotation design – Integrated ribs or wings prevent the plug from spinning during screw insertion, ensuring a secure and tight fit every time.
PE material (Polyethylene) – Lightweight yet strong, resistant to moisture, chemicals, and temperature variations, making them suitable for both indoor and outdoor concrete installations.
Full size availability – From M6 to M16 and all common intermediate sizes, we cover your requirements for light to heavy loads. Custom sizes are available upon request.
High load capacity – Engineered for strong loading in concrete (grades C20/25 or higher). Each plug can withstand pull-out forces up to 150 kg depending on size and installation conditions.
Easy installation – Simply drill a hole, insert the plug, and tighten the screw – no special tools needed. The expansion action grips the concrete firmly.
Cost-effective wholesale pricing – As a trading company with an annual export value of US$1–1.5 million, we offer competitive factory-direct prices without compromising quality.

Frequently Asked Questions (FAQ)
