Clarification on Anchor Type and Design

This anchor’s design includes several important features that determine its performance and use.

• Anchor Type: This is a sleeve anchor, a type of expansion anchor that comes as a pre-assembled unit. It includes a threaded bolt with a conical expander at the end, a textured expansion sleeve, a washer, and a hex nut. It is designed for “through-fixing,” which allows for a faster installation process.
• “Fish-Scale” Texture: The expansion sleeve features a directional, overlapping pattern that resembles fish scales. When the anchor is tightened and the sleeve expands, this texture bites into the surrounding base material, providing a powerful frictional hold and helping to prevent the anchor from spinning during installation.
• “WZP” (White Zinc Plated): This indicates the surface finish. The carbon steel components are electro-plated with zinc, resulting in a clear or bluish-white appearance. This finish provides a standard level of corrosion protection suitable for dry, indoor environments. It is the most common and economical plating option for general-purpose fasteners.

Product Mechanism and Installation

The anchor’s holding power is generated by the expansion of the textured sleeve against the base material. Please note that the installation instructions provided on the source page are partially incorrect and could be confusing. The correct mechanism and installation process for this type of sleeve anchor are as follows:

• Mechanism: The anchor assembly consists of a bolt with a tapered cone at its base, the fish-scale expansion sleeve, a flat washer, and a hex nut. When the hex nut is tightened, it pulls the bolt’s shaft upwards. This action draws the tapered cone at the base of the bolt into the expansion sleeve, forcing the sleeve to expand outwards and press firmly against the inner walls of the drilled hole.
• Correct Installation Process:
  1. Drill the Hole: Using a carbide-tipped drill bit that matches the anchor’s diameter, drill a hole into the base material (e.g., concrete). The hole should be drilled to a depth slightly greater than the length of the anchor.
  2. Clean the Hole: Thoroughly clean the hole of all dust and debris using a wire brush and compressed air or a hand pump. A clean hole is crucial for achieving the anchor’s maximum load capacity.
  3. Insert the Anchor: Place the item to be fastened over the hole. Insert the complete sleeve anchor assembly through the fixture’s mounting hole and into the drilled hole until the washer and nut are snug against the surface of the fixture.
  4. Set the Anchor: Using a wrench, turn the hex nut clockwise. This will expand the sleeve within the hole and securely clamp the fixture to the base material. Continue to tighten until the anchor is firmly set or the manufacturer’s recommended torque value is reached.
