• Type: Heavy-Duty Sleeve Anchor with Hexagon Bolt

• Material: Carbon steel, zinc plated ($\ge$ 5 µm) for corrosion protection in dry indoor environments.

• Quantity: 1 piece (Sold individually)

Dimensions & Technical Specifications

• Drill Hole Diameter ($d_0$): 8 mm (requires an 8 mm masonry/concrete drill bit).

• Total Anchor Length ($L$): 45 mm (compact profile for shallow or restricted embedment).

• Metric Thread Size ($d$): M6 internal bolt.

• Maximum Fixture Thickness ($t_{fix}$): 2 mm (optimized for thin metal plates, brackets, or steel framing tracks).

• Minimum Drill Hole Depth ($h_1$): 50 mm.

• Effective Embedment Depth ($h_{ef}$): 35 mm.

Design Features & Key Benefits

• Three-Piece Expansion Sleeve: Torquing the hexagon bolt draws the tapered cone into the sleeve, expanding the metal sections uniformly against the borehole walls for strong friction-locked holding power.

• Collapsible Plastic Section: Features an integrated plastic compression ring on the sleeve body. This section collapses during final tightening to securely pull the fixture flat against the face of the concrete, eliminating structural gaps.

• ETA Approved Security: Holds a European Technical Assessment approval for non-cracked concrete, validating its rated structural capacities for industrial and commercial projects.

Application:

Specified for structural steel staging, drywall track anchoring, mechanical plant attachments, and light-duty commercial installations. Ideal for anchoring steel guide rails, base plates, electrical/HVAC ventilation brackets, and thin metal cladding base components into solid concrete.
