Description

  • 【Efficient Through-Fixing Installation】Engineered with a "hole-size equals bolt-size" design (3/8"), these sleeve anchors allow for direct installation through the fixture and into the substrate. This streamlined process eliminates the need to move equipment or re-align holes, making it an ideal choice for high-volume 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 workshop floors or walkways, effectively preventing trip hazards while maintaining a professional appearance.
  • 【360° Uniform Expansion Grip】Featuring a full-length expansion sleeve, these bolts distribute holding power evenly throughout the hole. This superior load distribution reduces localized stress on the masonry, ensuring a reliable hold in solid concrete, brick, or stone without risking surface cracks or blowouts.
  • 【Industrial-Grade Corrosion Resistance】Constructed from high-strength carbon steel with a heavy-duty zinc coating. These fasteners are engineered to resist oxidation and environmental moisture, providing long-term structural integrity for indoor industrial shelving, utility racks, and storage solutions.
  • 【Optimized for Metal-to-Concrete Fastening】The 4-inch length is specifically optimized for securing metal brackets, base plates, and thin structural components TO masonry surfaces. Available in 25 and 50-count packs, these anchors offer a professional-grade solution for projects requiring secure, shallow-to-medium embedment depths.
