Clarification on Anchor Type and Design

This anchor has several key design elements that define its function and application.

• Anchor Type: This is a sleeve anchor, a pre-assembled fastener that includes a threaded bolt, an expansion sleeve, a washer, and a nut. It is a “through-fixing” anchor, meaning it can be installed through the fixture and into the base material in one step.
• “Fish-Scale” Texture: The exterior of the expansion sleeve is stamped with a directional, overlapping pattern resembling fish scales. When the anchor is tightened, this texture bites into the wall of the drilled hole, creating a superior frictional hold and preventing the anchor from loosening or spinning, especially in less-than-perfect base materials.
• “YZP” (Yellow Zinc Plated): This refers to the surface treatment. The carbon steel components are electro-plated with zinc and then treated with a yellow chromate conversion coating. This finish provides a higher level of corrosion resistance compared to standard white/blue zinc plating, making it suitable for indoor applications where moisture may be present.

Product Mechanism and Installation

The anchor achieves its holding power by the expansion of its sleeve. Please note that the installation instructions provided on the source page appear to be incorrect and describe a different type of anchor. The correct mechanism and installation for a sleeve anchor are as follows:

• Mechanism: The anchor consists of a bolt with a tapered cone at its base, a textured expansion sleeve, a washer, and a hex nut. When the hex nut is tightened, it pulls the bolt upwards. This action draws the tapered cone at the base of the bolt up into the expansion sleeve, forcing the sleeve to expand outwards and press firmly against the surrounding base material. The fish-scale texture maximizes the grip of this expansion.
• Installation Process:
  1. Drill the Hole: Using a carbide-tipped drill bit that matches the anchor’s diameter, drill a hole through the item you are fastening and into the base material (concrete, brick, etc.). The hole depth should be slightly greater than the anchor’s length.
  2. Clean the Hole: Remove all dust and debris from the drilled hole using a brush and compressed air or a blower. A clean hole is essential for achieving maximum holding power.
  3. Insert the Anchor: Insert the complete sleeve anchor assembly through the fixture and into the hole until the washer and nut are snug against the fixture.
  4. Set the Anchor: Using a wrench, tighten the hex nut. This will expand the sleeve and securely clamp the fixture to the base material. Tighten until the recommended torque is achieved or the anchor is firmly set.

Key Features

• Enhanced Grip: The unique fish-scale pattern on the sleeve provides superior friction and anti-rotation properties for a more secure hold.
• Good Corrosion Resistance: The Yellow Zinc Plating offers better protection against rust and corrosion than standard zinc plating.
• All-in-One Assembly: The anchor comes pre-assembled, simplifying handling and speeding up installation.
• Through-Fixing Design: Allows for fast installation as the hole can be drilled through the fixture itself.
• Versatile Application: Suitable for use in a wide range of solid and some hollow base materials like concrete, brick, and block.

Common Applications

• Construction: Securing wooden beams, metal brackets, handrails, and facade systems to concrete or brick walls.
• Furniture and Fixture Installation: Firmly attaching heavy shelves, cabinets, and racking to walls.
• Industrial Settings: Mounting machinery guards, equipment, and conduit to factory floors and walls.
• General Purpose: A reliable choice for any application requiring a strong, removable anchor in solid masonry.
