Clarification on Anchor Type and Terminology

It is important to understand the specific design and terminology associated with this anchor.

• Anchor Type: This is a torque-controlled expansion shield anchor. Its holding power is generated when torque is applied to the bolt or nut, which causes an internal cone to expand a metal shield against the walls of the drilled hole.
• “TAM Anchor”: “TAM” is a common industry name for this specific style of shield anchor.
• “One-Piece” vs. “Multi-Piece” Assembly: The term “One-Piece” in the title can be misleading. The anchor itself is a multi-piece assembly consisting of an expansion shield, an internal expander cone, and a bolt/nut. The term “One-Piece” likely refers to the shield component being manufactured from a single, solid piece of metal (as opposed to older, multi-part or welded shields), which enhances its strength and reliability during expansion.
• Material (Stainless Steel): This page focuses on the stainless steel (SS) variant, typically using high-quality grades like A2 (304) or A4 (316). This provides excellent protection against rust and corrosion, making it suitable for outdoor, marine, or chemically harsh environments. While the “Grade” section also lists carbon steel grades (4.8, 8.8, etc.), the primary material for this specific product listing is stainless steel. Carbon steel versions are likely also available from the manufacturer.

Product Mechanism and Installation

The anchor’s strength comes from the 360-degree contact and friction created by the expanding shield.

• Mechanism: The anchor consists of three main parts:
  1. The Expansion Shield: A cylindrical metal sleeve with precision-engineered slots that allow it to expand.
  2. The Expander Cone: A threaded conical nut located at the base of the shield.
  3. The Bolt/Stud: A standard machine bolt or threaded stud that passes through the shield and threads into the expander cone.
     When the bolt is tightened, it pulls the expander cone up into the shield, forcing the slotted sections to expand outwards and press firmly against the surrounding concrete or masonry.
• Installation Process:
  1. Drill the Hole: Using a hammer drill and a carbide-tipped bit, drill a hole to the specified diameter and depth in the concrete or masonry.
  2. Clean the Hole: Thoroughly clean all dust and debris from the hole using compressed air and/or a wire brush. This step is critical for achieving the anchor’s full load capacity.
  3. Insert the Anchor: Lightly assemble the anchor and insert it into the hole until the top of the shield is flush with the surface of the base material.
  4. Position the Fixture: Place the object to be fastened over the anchor and insert the bolt through the fixture’s mounting hole and into the anchor assembly.
  5. Tighten and Set: Using a wrench, tighten the bolt. This will draw the cone into the shield, expanding it to create a secure anchor point. Tighten to the manufacturer’s recommended torque specification.

Key Features

• High Load Capacity: Engineered for heavy-duty applications, providing excellent tensile and shear strength in solid base materials.
• Superior Corrosion Resistance: The stainless steel construction makes it ideal for long-term use in outdoor, humid, and corrosive environments.
• Reliable Expansion: The torque-controlled mechanism ensures a consistent and secure expansion within the base material.
• Versatility: Suitable for use in a wide range of solid materials, including concrete, solid brick, and stone.
• Removability: A key advantage of this anchor type is that the bolt can be removed after installation, leaving the anchor shield flush in the hole. This is useful for temporary fixings or equipment maintenance.

Common Applications

• Structural Fixings: Securing steel beams, support columns, and brackets to concrete foundations or walls.
• Heavy Machinery: Mounting industrial machinery, engines, and heavy equipment to factory floors.
• Racking and Shelving: Installing heavy-duty pallet racking and industrial shelving systems in warehouses.
• Marine and Coastal Applications: Fastening equipment, railings, and fixtures in ports, docks, and coastal buildings where salt spray is a concern.
• Infrastructure Projects: Securing barriers, signage, and other fixtures in civil engineering projects.
