Professional Summary

• Manufacturer: Mungo (Switzerland)

• Model/Article: 1581005 (MHA-B Series)

• Type: Heavy-Duty Sleeve Anchor with Threaded Bolt and Nut

• 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 ($L$): 50 mm (compact profile for shallow or restricted embedment).

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

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

• 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 external hexagon nut draws the integrated tapered cone into the outer sleeve, causing the 10 mm metal sections to expand uniformly against the borehole walls for strong friction-locked holding power.

• Collapsible Compression Section: Features Mungo's signature plastic ring built onto the sleeve body. This section collapses during final torque application, pulling the fixture completely flush against the concrete face and removing any structural gaps or slack.

• ETA Approved Security: Holds a European Technical Assessment approval (ETA Option 7) for non-cracked concrete, validating its rated structural capacities for commercial and industrial engineering projects.

Application:

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