•No pre-drilling required
•Thread formed by collar bead
•Material displacement for chip-free screwing
•Drilling performance: 2x 1.25 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)

Field of Application:

The drilling performance in steel is 0.5-2.5 mm

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.
Do not use the screw in applications with direct exposure to the weather or in wet rooms with atmospheres containing chlorine gas.
