Technical Specifications
- Dimensions (H x L x W): 2.5mm x 50mm x 8mm
- Weight: 0.003 kg
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 and power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry
- 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
- Suitable for high chloride or SO2-contaminated areas with exposure to splash water or fog
