Description

  • 【Efficient Through-Fixing Installation】Featuring a "bit-size equals bolt-size" design (3/8"), these sleeve anchors allow you to drill directly through your fixture and into the masonry. This streamlined process eliminates the need to move heavy items or re-align holes, significantly speeding up structural mounting tasks.
  • 【Safety-First Flush Mount Finish】The countersunk flat-head design ensures the anchor sits perfectly flush with the mounting surface once tightened. This low-profile finish is essential for high-traffic areas like garage floors, walkways, or patio bases, effectively eliminating trip hazards while maintaining a professional look.
  • 【360° Uniform Expansion Grip】The full-length expansion sleeve distributes holding power evenly across the entire surface of the hole. This superior load distribution minimizes localized stress, providing a reliable hold in solid concrete, brick, or stone without causing the substrate to crack or blowout at the edges.
  • 【Corrosion-Resistant Zinc Plating】Manufactured from high-strength carbon steel with a heavy-duty zinc coating. These fasteners are engineered to withstand environmental moisture and oxidation, ensuring long-term structural integrity for both indoor workshop equipment and outdoor residential fixtures.
  • 【Specialized for Masonry Anchoring】Specifically designed for securing wood beams, metal brackets, or plates TO concrete and masonry surfaces. While ideal for anchoring sill plates or deck posts to foundations, please note these are not intended for wood-to-wood applications. Available in 25 and 50-packs for projects of any scale.
  • 【Pro Tip】For a secure fit, ensure the hole is cleaned of all dust and debris before inserting the anchor. The 5-inch length is optimized for securing standard 2x lumber (1.5" actual thickness) to concrete with ample embedment depth.
