• Model/Article: 1591008 (MHA-S Series)

• Type: Heavy-Duty Sleeve Anchor with Hexagon Bolt

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

Dimensions & Technical Specifications

• Drill Hole Diameter ($d_0$): 10 mm (requires a 10 mm masonry/concrete drill bit).

• Total Anchor Length ($L$): 80 mm (extended profile for thicker fixtures).

• Metric Thread Size ($d$): M8 internal bolt.

• Maximum Fixture Thickness ($t_{fix}$): 30 mm (allows fastening materials up to 3 cm thick to the concrete base).

• Minimum Drill Hole Depth ($h_1$): 60 mm.

• Effective Embedment Depth ($h_{ef}$): 40 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, framing anchors, mechanical plant attachments, and warehousing setups. Ideal for anchoring steel guide rails, heavy industrial racking, base plates, ventilation brackets, and internal safety barriers.
