•No pre-drilling required
•Thread formed by collar bead
•Material displacement for chip-free screwing
•Drilling performance: 2x 0.7 mm in sheet steel

Application area:

For example: Splice plate connection for steel and aluminium profile panels, screwing of ventilation ducts
Environmental conditions - dry interior areas
Fulfils tightness class D in the leakage test for air duct systems in accordance with DIN EN 12237 | DIN EN 1507 | DIN EN 12599 (internally tested)

Advantages:

No corrosion caused by rusting metal chips
Greater tightness in ventilation duct construction due to the perfectly fitting thread shape

Advice:

Chip-free mounting - sheet metal is displaced by screws rather than cut/drilled.
Bit is included in the PU.
Do not use the screw in applications with direct exposure to the weather or in wet rooms with atmospheres containing chlorine gas.
