Key Features
- Universal partially threaded screw made of high-quality austenitic A2 stainless steel for wood-wood connections (spruce) in outdoor areas exposed to the elements
- Ideal power transmission thanks to RW drive
- More power due to larger contact area at the bit
- More stability, one-handed working, precise positioning due to the tight-fit recess and perfect fit of the bit
- Fewer bit changes, one bit for many screw diameters
- Compatibility with previous AW drive
- Higher breaking torque
- Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the single thread
- Better anchoring thanks to higher thread flanks
- Smooth thread start ensures optimised recessing and biting of the screw
- Reduced splitting effect due to displacement effect of the dome-shaped milling elements in the tip
- Friction-reduced thread rotation allows reduction of the screw-in force to be applied
- Stainless mounting for accessible wood connections in outdoor areas exposed to weathering
- Made of austenitic, non-magnetic and non-rusting A2 stainless steel
- Can be used in rural or urban environments or industrial atmospheres without significant exposure to chlorides or SO2
- With friction-reducing slide coating for easy fastening
