4 pcs fixing anchor with Hex Bolt

The Duojia 4-Piece Fixing Anchor with Hex Bolt is a robust, heavy-duty expansion anchor designed for secure, through-fixture fastening in solid base materials like concrete and masonry. This anchor assembly, commonly known as a sleeve anchor, is manufactured from high-tensile carbon steel and features a durable Yellow Zinc Plated (YZP) coating for enhanced corrosion resistance. Combining a standard hex bolt head for easy installation with a powerful expansion mechanism, this anchor provides a strong and stable connection, making it an ideal choice for construction projects, industrial equipment mounting, and other demanding applications where reliability is paramount.

Product Details

This anchor is a pre-assembled, four-component system designed for maximum performance and ease of use. The assembly includes:

  1. The Hex Bolt: A standard, precision-machined hex head bolt that allows for easy and controlled tightening with common wrenches or sockets.
  2. The Expansion Sleeve: A cylindrical steel shield with expansion slots that forms the main body of the anchor.
  3. The Tapered Cone: A threaded cone-shaped nut located at the base of the anchor.
  4. The Washer: A flat washer positioned under the bolt head to distribute the load evenly onto the fixture.

Installation is straightforward. The entire anchor is inserted through the fixture and into a pre-drilled hole in the base material. As the hex bolt is tightened, it pulls the tapered cone up into the expansion sleeve. This action forces the sleeve to expand outwards, creating a strong, 360-degree frictional grip against the walls of the hole, securing both the anchor and the fixture firmly in place. The Yellow Zinc Plating (YZP) provides a durable protective layer against rust and corrosion, extending the anchor’s service life.
