Mungo 5220122

Professional Summary

• Manufacturer: Mungo (Switzerland)

• Article / Part Number: 5220122

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

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

Dimensions & Installation Specs

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

• Total Length ($L$): 60 mm (extended length variant)

• 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 thick structural steel.

Key Features & Engineering

• Deep Penetration Drilling: The integrated structural drill tip instantly bores, taps, and fastens through heavy steel sections without walking, while the 60 mm length allows for thicker clamped materials.

• Maximum Clamping Power: The hexagonal head profile accommodates massive installation torque from professional impact drivers without stripping or camming out.

• Flanged Structural Seal: The built-in wide washer design perfectly distributes the high clamping force, preventing deformation of the secured profile and dampening structural vibrations.

Application Range:

Fastening thick structural steel sheets, multi-layered metal frames, heavy-gauge roofing profiles, structural facade brackets, and industrial framing systems directly onto thick steel columns or girders.
