Professional Summary

• Manufacturer: Mungo (Switzerland)

• Article / Part Number: 5220141

• Product Line / Type: Metal Frame Screw / Drywall-to-Steel Fastener (Extended Variant)

• Material & Coating: High-grade Carbon Steel, premium Black Phosphated (formulated for high resistance against wet plaster compounds and moisture corrosion).

Dimensions & Installation Specs

• Screw Diameter ($d$): 3.5 mm (slim, high-precision profile)

• Total Length ($L$): 35 mm (optimized for multi-layer or thick single-layer sheeting)

• Drive Type: PH2 (Phillips No. 2) (standard crosshead profile for automated drywall screw guns and high-speed drivers).

• Thread Type: Fine Thread (engineered specifically for dense mechanical grip inside steel profiles).

• Head Type: Bugle Head (countersinks flush into gypsum core without tearing the outer lining).

Key Features & Engineering

• Needle Point Sharpness: The hardened pierce point ensures instantaneous centering and clean puncture through light-gauge steel tracking without slipping or pre-drilling.

• Corrosion Immunity: The black phosphate chemical treatment guarantees that rust will not bleed through finished painted or wallpapered surfaces after jointing.

• High Anti-Pullout Friction: Optimized thread pitch ensures a tight, vibration-proof lock within the interior steel framework even when holding double layers.

Application Range:

Fixing double-layer gypsum boards (GKL), thick fire-resistant panels, acoustic linings, or structural boards to standard interior light-gauge metal stud partitions and ceiling track frameworks.
