RAPID® Hardwood
Rapid Hardwood can be inserted into hardwood without predrilling.
1 | Head geometry
Underhead milling mockets for optimal countersink:
- Smooth
- Gentle on material
- Also ideal for fittings
2 | Straight friction part
The new optimized friction section considerably reduces screw resistance:
- Less force required when screwing in
- Fast screwing
- Improved battery life of the drill/driver unit
3 | Thread
Single thread:
- Minimized blast effect
- Improved pull-out values
- Quicker screwing
4 | Tip
New improved patented compression tip:
- Improved bite in of the screw
- Lower splitting effect
Available sizes
RAPID® Hardwood are available in 8 x 120 to 8 x 240 mm.

Counter Sunk
Countersunk heads are counter-sinkable in wood or even in prepared steel plates. The milling pockets reduce the fraying and splintering of the wood.
Friction Part
The friction part reduces screwing resistance by opening the hole slightly wider than the screw shank. It is usually combined with the half thread.
Friction Part Geometries
Partially Threaded
Partially threaded screws, also known as half thread, pull timber members or steel plates and timber together. For the design head pull-through and withdrawal of thread must be checked. Lateral loads as well as axial loads are efficient transferred.
The axial load capacity of the thread in comparison to the countersunk head is approx. 3:1. Using a washer head screw leads to a similar performance of the thread pull out and the head pull through capacity.
Compactor Tip
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.
