Mungo 5137214

Professional Summary

• Manufacturer: Mungo (Switzerland)

• Article / Part Number: 5137214

• Product Line / Type: m2r Throughbolt Anchor (Premium Wedge Anchor)

• Material Composition: Stainless Steel A4 (AISI 316). Offers ultimate, long-term corrosion protection against salt water, chemical vapors, industrial pollution, and aggressive outdoor coastal or urban atmospheres.

Dimensions & Installation Specs

• Thread Size ($d$): M12 (heavy thread profile for high load capacities).

• Total Anchor Length ($L$): 145 mm (extended heavy profile variant).

• Drill Hole Diameter ($d_0$): 12 mm

• Maximum Fixture Thickness ($t_{fix}$): 50 mm (allows clamping of thick structural steel brackets, base adapters, or heavy timber plates up to 50 mm thickness).

Key Features & Engineering

• European Technical Assessment (ETA): Officially approved under ETA (Option 7) for safety-critical, high-load structural anchoring in non-cracked concrete.

• Heavy-Duty Expansion Clip: Features a robust 3-piece stainless steel expansion band that grips the concrete borehole wall with high friction, ensuring minimal displacement under massive tensile loads.

• Cold-Formed Construction: The structural body is cold-formed to maximize steel density, high fatigue resistance, and shear load capabilities under structural shifts.

• Impact Protection Head: The top section is intentionally designed to withstand heavy hammer strikes during setting without ruining the M12 threads.

Application Range:

Industrial and heavy structural anchoring in concrete $\ge$ C20/25 and hard natural stone. Ideal for securing structural steel columns, heavy-duty machinery bedplates, exterior curtain walls (facades), stadium seating nodes, safety barriers, and marine/coastal infrastructure.
