Key Features
- Universal partial-thread screw for robust use in timber construction or temporary anchors in non-structural systems.
- Large RW recess ensures maximum load transmission for fast, gap-free fastening of wood-to-wood connections in dry indoor or wet areas.
- Ideal power transmission thanks to RW drive with larger contact area at the bit.
- More stability, one-handed working, precise positioning due to tight-fit recess and perfect bit fit.
- Fewer bit changes, one bit for many screw diameters; compatibility with previous AW drive.
- Easy countersinking in hard wood surfaces with slightly smaller 60° countersunk head and increased head height.
- Significant reduction in force required when fastening due to milling shank displacement effect.
- Minimized risk of screw breakage due to high breaking torque.
- Reduced risk of injury from protruding metal chips due to integration of milling shank into thread.
- High protection of application tools; no over-tightening or stripping and high feed.
- Higher power transmission in hardwoods due to reinforced, asymmetrical thread flank geometry of coarse thread.
- Better anchoring thanks to higher thread flanks and smooth thread start for optimized engagement.
