Professional Summary

• Manufacturer: Mungo (Switzerland)

• Model/Article: 1581213 (MHA-B Series)

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

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

Dimensions & Technical Specifications

• Drill Hole Diameter ($d_0$): 12 mm (requires a 12 mm masonry/concrete drill bit).

• Total Anchor Length ($L$): 130 mm (extended profile for thick fixtures or deep anchoring requirements).

• Metric Thread Size ($d$): M10 internal stud.

• Maximum Fixture Thickness ($t_{fix}$): 65 mm (allows thick structural components or wooden beams up to 6.5 cm to be fastened directly to the concrete surface).

• Minimum Drill Hole Depth ($h_1$): 75 mm.

• Effective Embedment Depth ($h_{ef}$): 50 mm.

Design Features & Key Benefits

• Heavy-Duty Sleeve Expansion: Torquing the external hexagon nut draws the integrated tapered cone into the outer sleeve, causing the 12 mm metal sections to expand uniformly and grip the concrete borehole with strong frictional resistance.

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

• ETA Code Compliance: Backed by a European Technical Assessment (ETA Option 7) approval for non-cracked concrete, ensuring calculated safety factors and ultimate load-bearing performance on commercial construction sites.

Application:

Engineered for industrial anchoring, heavy carpentry, and structural steel attachments. Ideal for securing thick wooden ledger boards, structural timber beams, warehouse racking base plates, industrial machinery, ventilation brackets, and protective internal safety barriers into solid concrete.
