Ideal power transmission thanks to RW drive |
Visually appealing screw connection on wood surface with the option of countersinking like a countersunk head |
Significant reduction in the amount of force required when fastening in the screw |
No over-tightening or stripping and high feed |
Smooth thread start ensures optimized recessing and biting of the screw |
High strength values and ductility |
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 |
High head penetration values and strong combination of two wooden components due to the large head diameter |
Less splitting when immersing the shank due to the displacement milling effect of the milling shank |
Minimized risk of screw breakage due to high breaking torque |
Reduced risk of injury from protruding metal chips due to the integration of the milling shank into the thread |
High protection of the application tools |
Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of the coarse thread |
Better anchoring thanks to higher thread flanks |
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 |
Adjusted heat treatment guarantees high strength values and high ductility |
