Product description

  • High-Quality Material Our concrete screws are made of high-quality medium carbon steel, with excellent material strength. The surface has a special blue coating, which enhances corrosion resistance, ensures long durability, and prevents rust effectively.
  • Practical Design The screws have a hexagon flange head (enhanced anti-slip & load-bearing) and conical diamond tip (speeds up drilling, penetrates concrete slabs well). With high-low threads high threads cut masonry fast, low threads offer stability, forming removable fastening.
  • Versatile Application Ideal for securing fixtures (e.g., wall hangers, small brackets) to masonry, concrete, brick, and block surfaces, suitable for home DIY, minor decoration, and equipment fixing.
  • Easy Installation No expansion tubes needed you can install directly into substrates. The set comes with necessary bits (hexagon socket bit & drill bit), simplifying steps and making installation easy even for beginners.
