Features
| 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 |
Benefits & Advantage
| 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 |
Applications
The partial thread starting immediately below the shank allows for wood to wood connections designed to pull together. The screw thread is positioned entirely in the lower component once screwed in.
