Mungo 1581611 (MHA-B Series)

Professional Summary

• Manufacturer: Mungo (Switzerland)

• Model/Article: 1581611 (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 ($d_0$): 16 mm (requires a 16 mm industrial masonry/concrete drill bit).

• Total Anchor Length ($L$): 110 mm (extended profile for deep structural embedment).

• Metric Thread Size ($d$): M12 heavy-duty internal stud.

• Maximum Fixture Thickness ($t_{fix}$): 25 mm (allows structural components up to 2.5 cm thick to be fastened directly to the concrete surface).

• Minimum Drill Hole Depth ($h_1$): 95 mm.

• Effective Embedment Depth ($h_{ef}$): 70 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 thick 16 mm metal sections to expand uniformly and grip the concrete borehole with extreme 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 heavy industrial anchoring, structural steel infrastructure, and civil engineering projects. Ideal for securing structural columns, massive warehouse racking base plates, industrial machinery foundations, heavy crane guide rails, stadium balustrades, and protective highway steel barriers.
