Professional Summary

• Manufacturer: Mungo (Switzerland)

• Article / Part Number: 5220160

• Product Line / Type: Metal Frame Wafer Head Screw / Sheet Metal to Steel Fastener (Compact Variant)

• Material & Coating: High-grade hardened Carbon Steel, premium Zinc Plated (engineered for high protection against oxidation and construction-site moisture).

Dimensions & Installation Specs

• Screw Diameter ($d$): 3.9 mm

• Total Length ($L$): 19 mm (optimized short length for quick, low-clearance metal framing joints)

• Drive Type: PH2 (Phillips No. 2) (standard crosshead for precision stability and high torque transmission).

• Tip Type: Self-Drilling Drill Point (Сверло) — cuts through steel profiles cleanly without pre-drilling.

• Head Type: Wafer Head (Flanged / Пресс-шайба) — low-profile ultra-flat head with a broad integrated washer.

Key Features & Engineering

• Ultra-Flat Wafer Head: The broad, low-profile flange maximizes surface contact area to clamp thin metal sheets tightly, while remaining flush enough so that overlying plasterboards don't bulge or bump.

• Rapid Self-Drilling Point: The integrated drill tip is calibrated to instantly bite, bore, and tap through steel framework connections (up to 2.0 mm total thickness) without walking.

• High Pull-Out & Vibration Resistance: Fine thread engagement combined with the broad head flange guarantees a permanent mechanical lock that withstands acoustic and structural vibrations.

Application Range:

Stitching metal-to-metal tracking and structural studs together, mounting direct interior ceiling suspension hangers (brackets/peshkas) to ceiling profiles, fastening light-gauge sheet metals, and securing metal component linings.
