Fully threaded screws are used for timber to timber connections.
1 | Head geometry
- Reduced split effect
- Deep countersinking of the head is possible
- Ideal for connecting steel components
2 | Thread
Full thread optimized for more efficient installation:
- Excellent pull-out values
- Excellent pressure values
- Maximum load-bearing capacity
3 | Tip
With patented half-tip, partially combined with compactor tip:
- Reduced edge distance
- Minimized blast effect
- Improved service life of the driving device thanks to 50 percent lower fastening torque
- No pre-drilling required
- Quick bite even when drilling in inclined position
RAPID® Fullthread are available in 8 x 120 to 12 x 1000 mm.
|Head Geometry||Counter Sunk, Cylinder Head|

Countersunk heads are counter-sinkable in wood or even in prepared steel plates. The milling pockets reduce the fraying and splintering of the wood.
Reduced blast effect Head is able to countersink deep into material Improved force transfer thanks to deeper drive
Fully threaded screws can withstand much higher forces acting along the screw axis because the load is held by the longer thread. The longer thread also increases shear capacities due to the rope effect.
Steel to wood and also applications between timber members are common. RAPID® screws have very high withdrawal capacities through axial loading and can be used for installation angles from 90° (side grain) to 0°, driven into end grain. Many applications are possible, e.g. reinforcement in tension, shear and also in compression, cost efficient solutions with crosswise paired screws or even arranged under 45° connections.
The compactor tip reduces the torque resistance by opening the hoe slightly bigger than the core diameter of the screw. This helps to prolong the battery life of the screwdriver for longer machine life and saves time during installation.
The half tip ensures less deviation of the screw during install as well as reducing the splitting effect and therefore smaller edge and end distances can be achieved.
