• Model/Article: 1581014 (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 ($L$): 145 mm (extra-long profile for deep anchoring and thick fixtures).

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

• Maximum Fixture Thickness ($t_{fix}$): 95 mm (allows materials or layered assemblies up to 9.5 cm thick to be fastened directly to the concrete surface).

• 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 for non-cracked concrete, validating its rated structural capacities for commercial and industrial engineering projects.

Application: Specified for heavy carpentry, structural framing, timber construction, and industrial plant setups. Ideal for anchoring thick wooden ledger boards, structural timber beams, insulation-penetrating fixtures, heavy machinery base brackets, and protective internal barriers into solid concrete.
