Key Features
- Universal full-thread screw for fast, permanent fixing of wood-wood or metal-wood connections
- 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 tight-fit recess and perfect fit of the bit
- Fewer bit changes, one bit for many screw diameters
- Compatibility with previous AW drive
- No over-tightening or stripping and high feed
- Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the coarse thread
- Better anchoring thanks to higher thread flanks
- Smooth thread start ensures optimized recessing and biting of the screw
- Reduced splitting effect due to displacement effect of dome-shaped milling elements in the tip
- Friction-reduced thread rotation allows reduction of screw-in force
- High strength values and ductility
- Adjusted heat treatment guarantees high strength and ductility
