Key Features
- Made of high-quality austenitic HCR stainless steel 1.4539 with countersunk head for wood-wood fastening in areas severely exposed to corrosion (corrosion resistance class IV)
- 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
- Form-fitting connection to metal fittings or in wooden products with high bulk density
- Perfect fit of 90° head in fitting parts with metal countersinks
- Pulls together without head milling due to lack of milling elements below the head
- 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
- Suitable for high chloride or SO2-contaminated areas with simultaneous exposure to splash water or fog
- Made of high corrosion-resistant, austenitic, non-magnetic and non-rusting stainless steel, class HCR
