Mungo 5220121

Professional Summary

• Manufacturer: Mungo (Switzerland)

• Article / Part Number: 5220121

• Product Line / Type: Heavy Duty Metal Frame Screw / Self-Drilling Structural Fastener

• Material & Coating: High-grade hardened Carbon Steel, premium Zinc Plated for robust atmospheric corrosion resistance in structural environments.

Dimensions & Installation Specs

• Screw Diameter ($d$): 5.5 mm (thick heavy-gauge structural body)

• Total Length ($L$): 38 mm

• Drive / Head Type: Hexagon Head with Integrated Washer (Hex Drive) — optimized for high-torque impact wrenches and nut setters.

• Tip Type: Heavy Duty Self-Drilling Drill Point (Сверло) — engineered to cut directly through structural steel.

Key Features & Engineering

• Thick Gauge Steel Penetration: The heavy-duty drill tip is engineered to easily bore, tap, and fasten through thick structural steel sheets and metal frames without any pre-drilling.

• High Torque Resistance: The hexagonal head configuration prevents stripping (cam-out) even under extreme installation torque.

• Integrated Washer Base: The wide flange/washer design under the hex head distributes the clamping pressure evenly across the metal surface, ensuring a tight, vibration-resistant structural seal.

Application Range: Fixing structural steel sheets, heavy-duty metal frame studding, roofing profiles, metal brackets, and thick cladding frameworks directly to structural steel beams or metal framing networks.
